Based on 1950-64 Soviet and 1952-62 Western published sources, a review of crystal (quartz) stabilizers, their circuits, and modes of operation is offered. These ways for enhancing the stability of cry is tal -controlled oscillators are recognized: (1) Higher Q-factor of crystal resonator; (2) Its higher temperature stability; (3) Perfecting oscillator circuits. These topics are covered: Superhigh Q-factor resonators (quartz bars, beveled bars, quartz lenses); Stepping up temperature stability (thermostatic control, reactance-thermistor compensator, P-n-junction capacitance compensator); Operation stability in transistorized oscillators (reactive instability, phase instability, nonlinear correction, inertial nonlinearity, ACC, pulse excitation). A quartz servo oscillator circuit described by Leo Norman (Froc. IRE, 1958, no. 1) is also mentioned. Orig. art. has: 5 figures and 10 formulas. SUB CODE: 09 SUBM DATE.

Since the quality factor of quartz resonators is very high,,the decrease in amplitude of the oscillations between the pulses is negligible. The oscillator system consists basically of an amplifier, a frequency-divider and a quartz- crystal resonator. The frequency-divIder is based on a multi- vibrator circuit and generates a waveform whose frequency is near to the third (or another odd) subharmonic of the quartz- crystal frequency. The pulses from the output of the multi- vibrator are applied to the crystal where they excite its free Card 1. 311~67~ s/142/61/004/005/013/014 Shock-excited .... r,,192/E382 15 - 25 V. A shock-excited oscillator operating at 500 kc/s (with feedback at the fifth subharmonic) was also investigated and it was found that the generated frequency was practically independent of the supply voltage.

Abstract: When 468 healthy, 20-45 years old life savers (from a mountain area) were placed in a restful position into a heat chamber with a 500 CC-7 teLTerature and a relative humidity of 50 percent, their maximal arterial pressure (AP) decreased considerably during the first 30 minutes. The decrease which followed then was insignificant, for the lowest AP amounted to 68 nm of the mercurial Card 1/3 27 POI,rM/Hunan and Animal PhysioloE7.

During the first 60 minutes of the experi- ment a significant decrease of the minimal AP Was observed, Utbri JttIPef=ined on the same level . In 25 percent of the tested persons a decrease of the minimal AP dawn to zero was observed, although their wellbeing remained unchanged as compared to the other subjects. During the first 30 minutes of the experi- ment the blood pressure increased considerably. Sub- sequent increases were insignificant. After another 30 minutes they reached a constant Mgt level, which did not change until the end of the experiment. After 30 minutes the average pulse rate increased to 115, and reached 138 beats per minute at the end of the test. In 325 workers an examination of the arterial tonus did not reveal specific changes of any kind. Card 2/3 POUIND/Human and Animal Physiology. Thermoregulation.

TITLE: A Device fcr Studying the Processes of Film Formation in Steel PERIODICAL: Zavodskaya laboratoriya, 1960, Vol. 26, No. 12, PP-1422-1424 TEXT: The principle of the "filmoscope" developed by the author is based upon the increased emissivity of the surface of the liquid steel during its oxidation. In steel with non-oxidized surface, the coefficient of the emissivity is about equal to 0.45, which value rises to 0.8-0.9 in the presence of an oxide film. The scheme of the "filmcscope" is given in Fig.1, and that of tUe device for investi~_,ating film formation on the surface of liquid steel in Fig. 2. The device descriled in Fig. 2 is also used to study the film formation under the action of various gases. For this purpose, the "filmoscope" is fastened in a bell, through which the -as is 0 allowed to Dass. The bell contains a thermocouple and a scraping-i-ron for removing sia.-s. The bell was further placed under a crucible, and the latter was Inserted into the inductor of a high-frequency furnace.

A mixture of coke and blast-furnace gases serves as fuel, the flarne being enriched with fuel oil. The Venturi-type nozzles are equipped with ducts at their ends permitting the passage of compressed air. The thermal regime is controlled automatically. The chromium- magnesite crown is of the buckstay-and-tie-rod type. It was established, during actual operation, that the gas opening should be raised by 150-200 mm, the slope of the rear wall be changed from 5305W to 480, and the diameter of the air/wa5te- Card 1/2 gas valve be increased to 1800 mm.

Chernaya metallurgiya, 1958, Nr 1, pp 112-116 ABSTRACT: 4000-4500 m3 compressed air from blast-furnace turbo- blowers is delivered per hour into the ends of the gas tank of the 220-t ovens at the Voroshilovsk Metallurgical Plant. The employment of compressed air improves the fuel combustion process, thus making it possible to reduce the excess-air coefficient from 1. 5- 1.8 to 1.05- 1.15. Heating of the gas checkers is increased by 100-150'C. The tank-lining life is increased from 80 to 200 heats, and dust loss is reduced. The slag pockets require cleaning every 280-350 instead of 130- 160 heats. The rate of G burn-off during the finishing period is 8 Card 1/2 to 15% greater. When compressed air is employed, the melting SOV/ 137-58- 10-20563 An Investigation of the Thermal Functioning of Open-hearth FurnaceE (cont.) period is 20 minutes shorter, and the working period 13 minutes. The unit consumption of fuel, in conventional units, is 1316 less. Delivery of com- pressed air makes it possible to maintain higher heat inputs and obtain higher output rates from the furnaces. The heat intake of the bath rises by 40-60% with an air consumption of 2000 m3/hr, and even more at 45OOm3/hr. In the second half of the furnace, heat absorption declines when air is sup- plied, sometimes going to values close to zero. For a 250-500-t furnace, the optimum compressed-air delivery is 3000-5000 m3/hr; the precise amount requires determination by experiment in each individual instance. G.

The investigation was carried out on a 500-ton furnace during which schedules of the Giprostall and Stallproyekt were tested. The furnace was fired with a coke-oven blast furnace gas mixture carburised with oil.- The distribution of the reversing installation and mechanical graphs of reversing are shown in Figures 1 and 2. Heat radiation to the bath and towards the front walls were measured Cardl/4 simultaneously using VNIIMT and EPP-09 instruments, SOV/133-59-1-?/23 An Investigation of Schedules for Reversing Open-hearth Furnace Valves respectively. The comparative measurements of the intensity of semi-spherical heat radiation onto the bath and directed (towards the front wall) radiation during reverses according to Giprostall and Stal'proyekt schedules at various consumptions of coke-oven gas (VK blast-furnace gas (V D) , blown air (Vvv) and oil (G.) as well as various pressures in the furnace (Ap) are shown in Figures 3-6 and Table 1. It was found that during melting and refining periods, the radiation of heat onto the bath during reversing, according to both schedules, decreases not more than by 1% of the whole heat radiated during the half cycle of the heat exchange. During the period of heating up, this decrease amounts to 1.5%. In respect of heat radiated only from the moment of the beginning of the decrease in radiation tb the moment of its re-establishment the decrease in radiation amounts to 4-50/6 (Figure 7). The time interval during which the decrease in radiation takes place due to reversing amounts to 45 see. It is considerably Ca.rd2/4 higher than the calculated break in the flame (15 see). SOVM3-59-1-7/23 An Investigation of Schedules for Reversing Open-hearth Furnace Valves The smoothing influence of the lining of the working space of the 4urnace is less reflected on the directional heat radiation towards the front wall than on the intensity of semi-spherical radiation of heat to metal. Therefore, measurements of the directional radiation with the radiation pyrometer gave more accurate indications of the influence of reversing on the flame, the disappearance of the flame from one side and its reappearance on the other. The decrease in the directional radiation lasts about 35 see and amounts to 1.5-3.5% of its initial value. Thus, it was established that reversing according to both schedules is not accompanied by a considerable decrease in the amount of heat radiated during the heat-exchange cycle and that both schedules are satisfactory. The duration of the passage of gas and air into the working space from one side of the furnace and their displacement by the combustion products into the common flue on the other side of the furnace was investigated during reversing according to the Giprostall schedule. The entrance of air into the furnace was determined on the basis of the oxygen content Gard3/4 in the fume-air mixture in the air vertical flue and the SOV/133-59-1-?/23 Investigation of Schedules for Reversing Open-hearth Furnace Valves entrance of the mixed gas on the basis of CO2 content in the gas vertical flue. The moments of displacement of gas and air into the common flue were determined on the basis of changes in the chemical composition of gases in the waste-gas valves of the furnace. The experimental results are shown in Figures 8-12. The entrance of air and gas into the furnace takes place without any sharp transfer from combustion products to air and mixed gas. The actual time of the complete displacement of one type of atmosphere by another one is a few times longer than that calculated on the assumption that the combustion products are displaced frontally (without mixing) by air and gas. Changes in the gas pressure in the furnace during reverses are shown in Table 2 and Figures 13-14. It was found that on reversing according to Giprostal' schedule, the gas pressure in the furnace is lower. There are 14 figures and 2 tables. ASSOCIATION: VNIIMT,and zavod im.

The object of the in- C> vestigation was to obtain information on the possibilities of improving the furnace performance as well as to obtain some design data for 700-800 ton furnaces. The 500 and 250 ton furnaces were lined with basic refractories (mean ser- vice life of chrome-ma-nesite roofs from 400 to 450 heats). The furnaces were fired with a mixture of coke oven and blast furnace gas carburized with fuel oil. Compressed air was supplied (from blast furnace blowers) to the flame. Material and thermal balances of the 500 ton furnace are Card 1/4 sov/133/58-9-4/29 An Investigation of the Thermal Performance of a 500 Ton Open Hea:E, Furnace given in Tables 1 and 2 respectively. Heat absorption and the coefficient of utilization of heat were investigated using the method of "instantaneous reverse heat balance" which is based on measurements carried out during short time intervals. The dependence of the intensity of straight heat currents on the amount of compressed air supplied to the flame - Fig.1; the dependence of the coefficient of utiliza- tion of heat (A) and heat absorption (B) on the pressure under the roof during the individual smelting periods - Fig.2; the dependence of straight heat currents during the refining period on the coefficient of excess of air - Fig.3; the dependence of the coefficient of utilization of heat and coefficient of heat absorption o4 the thermal load 7with a supply of compressed air of 4000 m2/hr, during the individ- ual smelting periods - Fig.4; the dependence of the duration of melting period on the specific heat consumption and on the concentration of carbon after melt out at various thermal loads - Fig.5; the dependence of the duration of the melting period and specific heat consumption on the concentration of carbon after melt out at various thermal loads - Fig.G. On Card 2/4 the basis of the results obtained optimum thermal operating %V/133/58-9-4/29 An Investi.-ation of the Thermal Performance of a 500 Ton Open Hearth Furnace conditions for the 500 ton furnace were established (Table 3) which decreased the consumption of conventional fuel from 125 to 108 kg/ton at a duration of heats not exceeding 11.5 hours. In view of relatively lower heat losses per ton of smelted steel, the consumption of fuel in 500 ton furnaces is somewhat lower (15-20 km of conventional fuel) than in 250 ton furnaces. The use of compressed air has a positive effect on the thermal work of the 500 ton furnace, as it permits decreasing the coefficient of excess air to 0 9-1 05. At thermal loads of 35-40 mil. k cal/hr an average 5060 m3/hr of compressed air is required (varying the supply according to thermal loa4s during the individual smelting periods from 4000 to 5500 m2/hr). On the basis of the results obtained it can be expected that the character of the distribution of thermal currents and heat exchangge conditions in 700-800 ton furnaces under design will be approximately the same as Card 3/4 SoV/133/58-9-4/29 An Investigation of the Thermal Performance of a 500 Ton Open Hen-th Furnace in 500 ton furnaces. A decrease in specific heat losses in 700-800 ton furnaces should somewhat improve the coefficients of the utilization and absorption of heat in comparison with 500 ton furnaces.

The design and mode of operation of the slag pockets are shown in Fig 1-3. The design consists of an independent stationary roof and movable double walled box of a rectangular cross section, both halves of which are made from plate 20 mm thick with reinforcing ribs. The two halves of the box are bolted together. Rollers are connected directly to the bottom of the box. The box is placed along the axis of the slag pocket on rails. The internal walls of the box are lined"as follows: bottom loose layer - 30 mm, Card 1/2 layer of foamed chamotte 115 mm, silica lining of the SOV/133-59-6-14/41 Mechanisation of the Removal of Slag from Slag Pockets of Open Hearth Furnaces bottom - 195 mm, the same of the walls at the bottom - 345 mm, the same of the walls at the top - 215 mma Roofs of the removable slag pockets are supported by water cooled plates mounted on beams and n shaped columns. Under normal operating conditions the wear of roofs of slag pockets is uniform and amounts to 25 - 30 mm. per campaign at 400 - 450 heats. The durability of the roofs increased from 600 - 1000 heats to 1200 - 1500 heats. The duration ef repairs on transfer to removable slag pockets decreased from 7.7% of the total calendar time to 5-5% which is equivalent to an increase in the output of 5000 tons per year per furnace.

The authors mention this work in which pure coke-oven gas was used with the addition of turbine air into the side of the gas port and describe the adoption of practice with reduced (halved) quantities of blast-furnace gas which followed the coml;aetion of the first part of the work. On 250 and 500-ton furnaces, the blast-furnace gas consumptions were 3 000 and 4 500 m~'/hourj respectively, the coke-oven gas consumptions remaining unchanged and the specific fuel consumption being equivalent to the decrease in blast-lournace Cardl/3 130-58-2-6/21 Open-hearth Furnace operation on High-calorific Value Low-pressure Gas gas consumption. By increasing the poEt cross-sections,, an equally high temperature (about 1 350 C) was obtained for gas and air checkers. The slag pockets filled less rapidly, a higher furnace temperature and increased heat flows were obtained with the new practice: measurements with-, VIIIIT-designed probes on a 500-ton furnace are shown graphically. Three experimental heats were carried out on a 500-ton furnace without blast-furnace gas and the averages of the main operating results for this and ording y operation are tabulated (Table 1): the authors discuss these briefly and -point out that there seems to be an optimal gas pre-heat temperature. They consider the functioning of the gas checkers with pure coke-oven gas. A failure of the lining of the gas ports on a 500-ton furnace led to the combustion products losing enough heat to prevent ovei-- heating of the gas checkers and the furnace was worked on coke-- oven gas continuously for 1 1/2 months. The operating results show (Table 2) mean &creases of 0.7 hours and 21.8 kg/ton for tap-to-tap time and consumption of standard fuel, respectively. The authors recommend the coke-ovenEps firing of furnaces without blast-furnace gas, the cross-sectional area of the gas d2pyts being reduced to reduce the flow'of combustion 'orcdu-_-ts Car / 130-58-2-6/21 .

TITLE: Heat Balances of 500 and 250-t Gas-fired Open-hearth Furnaces (Teplovyye balansy 500 i 250-t gazovykh martenovskikh pechey) PERIODICAL: Izv. vyssh. uchebn. zavedeniy. Chernaya metallurgiya. 1958, Nr 3, pp 52-56 ABSTRACT: 500 and 250-t furnaces are heated by a mixture of coke and blast- furnace gas with an average thermal load of 36.8 x 1010 and 25.0 x 1010kcal/hr. Thl hearth areas of the furnaces are, respectively, 96.76 and-74.0 m , steel (St) production7being 8.65 and 6.75 t/m per day and heat time 12.4 and 10.33 hours. The necessary calculations and tables are provided. The in-put and a portion of the output side depend upon the batch. The fundamental heat losses of 500 and 250-t furnaces are approximately identical; they consist of carry-off of 0 heat and combustion products 30 /io and 33%, respectively) and loss in the cooling elements (12.2476 and 13.70/o). The remaining losses (by radiation, through the brickwork, etc.) are of somewhat smaller Card 1/2 magnitudebut they are greater in the 250-t furnace in virtually all SOV/137-58-11- 22083 Heat Balances of 500 and 250-t Gas-fired Open-hearth Furnaces cases. In accordance with the heat balances, the average unit consumption of con- ventional fuel is 123.6 kg/t for a 500- and 137 kg/t for a 250-t furnace. The greater efficiency of 500-t than of 250-t furnaces is due to the reduced heat loss per t of St, the better utilization of heat in the melting chamber, and the higher;.-rate of steel production (by 50-650/0).

Literature data are quoted indicating that autocarburization of gas can be obtained by preheating the gas to a temperature at which decomposition of methane,with the partial formation of higher hydrocarbons and carbon particles, takes place. Experience in firing a 250 ton open hearth furnace with preheated coke oven gas of the usual pressure instead of a mixture of coke oven and blast furnace gas is described. For this purpose the crOSB-sectional area of the outlets from dog houses was reduced from 0.45 to 0.22 m2 and the gas port was lowered. Compressed air in an amount of 3000 to 3500 m3/hr was introduced through the back faces Card 1/3 of the dog houses. The above measures permitted SOV/133-59-9-8/31 An Investigation of the Operation of a 250 Ton Open Hearth Furnace Fired with Coke Oven Gas increasing the velocity of the gas-air mixture from the dog house to 100 to 120 m/sec. The pressure in the gas vertical flue increased to the atmospheric pressure and at maximum thermal loads to 10 mm H20. The temperature of the upper checkers of gas regenerators was maintained at 1200 to 12500C. The consumption of oil remained the same as on firing with mixed gas. During the melting period, the flame was covering the bath satisfactorily but during the refining period at low thermal loads the length of the flame was insufficient. In this case, an improvement can be obtained by decreasing the coefficient of excess air to 0.9 to 1.0. Changes in the operating indices of the furnace on transfer to firing with hot coke oven gas are given in tables 1 and 2. The preliminary results obtained indicated that, in respect of productivity and fuel consumption, the furnace operation was satisfactory.

The furnace was put into operation in March, 1956. It was built in a melting shop designed for 250-ton furnaces. Main dimensions are given in the table and Fig.l. The roof is made from magnesite-chrome and regenerators from forsterite bricks. The first campaign lasted 381 heats with a mean output per heat of 489.5 tons and mean duration of 13.21 hours. The furnace was producing rimming steels (mainly Ct-W) with 58-65% hot pig and 35-42% scrap. A comparison of the dependence of the duration of heat, melting and refining periods and velocity of decarburisation during ore and pure boiling on the carbon content after melting for the 500-ton and a 250-ton furnace is given in Fig.2. Thermal conditions of the furnace operation are discussed in some detail and illustrated in Figs. 3-7. It is concluded that the results of the furnace operation were satisfactory, but somewhat lower than as designed, mainly due to organisational-technical defects (insufficient Uard 1/2 133-11-4/19 From Experience in Operating a 500-ton Open-hearth Yurnace supply of coke-oven gasI stoppages in the supply of burden materials, ladles, etc), as well as due to large metal losses during teeming and the following design defects: too low position of gas outlet, insufficient diameter of the waste gas valve on air duct (150 mm instead of 1 800 mm required) and insufficient capacity of slag ladles.
