A more intensive dehydration is observed with a sudden reduction of the pressure of the heat- ed liquid when the latter leaves the sprayer. The Card 1/5 dehydration process is achieved, by the heat of SOV/143-59-2-14/19 The Drying of Heated, Inorganic Solutions by Means of Spraying the, drying agent (flue gas), and by thEL in t e Ir i or heat of the atomized particles. The preliminary. heating of the solution causes agreduction of the ty and,surface tension, and consequently, viscosi it changes the character of the interme(liAte-phase surfaces and with them the spray di;BpeAion. eThere- by the basic laws are disturbed which are valid.for the dispersion.of a cold liquid flow. For-investigat-. ing the basic thermal and hydrody~iamiic- peculiari 'ties, of this drying processt an experimen-tall.semi-indus- trial drying chamber was built at the Kafedra'su- shil I nykh i teploobmennykh ustroystv MEI of Drying and Heat-gxchange Equipment of MEI). The drying chamber was built in such a way that one parameter of the process could be changed while all the others were kept constant. Provisions were made to perform the drying in a direct flow and in a counterflow of flue gao, or to feed the drying gases from the sides of the chamber. Figure 1 shows Card 2/5 a diagram of the drying: unit. The basic series of SOV/1 43-59-2-1-'V/19 TheDrying of Heated, Inorganic Solutions by Means of Spraying -tests was conducted with centrifugal sprayers. A total.of 60 experiments was made for which a 50% salt.solution was used as experimental liquid. The liquid consumption was changed from.70-260 kg/h, the 0temperature of the liquid was varied from 75- 300 0, the pressure of the liquid from 50-150 atm. The-tem 8erature of the flue gases was varied from 190 550 C. Kerosene was used as a fuel for heating the drying chamber. Since preliminary heating of the liquid causes a faster crystallization of the dispersed particles, the interaction of the flue gas components with the product is less intensive than when using a'cold liquid. The increase of the sulfur content of the dried material did not exceed the maximum permissible valup of 0.06% so The processing of the experimental data and tG'ir ana- lysis showed that the most favorable drying condi- 0 tions were obtained at a liquid temperature of.280 C, and at an initial gas temperature of 460 C.

When spray drying cold liquids the mass exchange factor at the same temperature of flue gases amounted to 8-12 kg/ m hour.

So far, peculiarities of flowing out and disinte- grating of a heated liquid stream were not consider- ed in the works of Soviet and foreign scientists. The authors established some characteristical hy- drodynamic phenomena of this process and some cal-- culated suggestions for the design of sprayers will be subject of future investigations. The authors mention only the four types of sprayers used dur- ing their experiments: a centrifugal sprayer with one tangential inlet a centrifugal sprayer with two tangential inlets, a centrifugal sprayer witly"a Card 4/5 special conical atomizer gnd a conical nozzle. The SOV/1143-59-2-14/19 The Drying of Heated, Inorganic Solutions by Means of Spraying experiments with the centrifugal sprayers, showed that their output was redUceg by 30-400 when the . liquid was heated to 260-290.C, in comparison with the cold liquid, The authors came to the conclusion that the preliminary heating increases the drying efficiency of heat-rqsistant inorganic liquids. The preliminary heating of the liquid prior to spraying permits the use of flue gases of fuels, with a low sulfur content as a drying agent. There are 2 tables, 1 diagram, 1 graph, and 2 Soviet re- ferences.

Sadc-hikov, TITLE-. The St.res-~,ed and Deformed State in the Cutting of Die t al PERIODICAL: I7,11.7estiya lrysshikh uchebnykh zavedeniy, Fizika, 1960, NG~6, PP-79-88 TEXT. The stressed and deformed~state in the cutting of ductile mptals is investigated. The process is assumed isothermal and steady, The deformation is of the plane type. The metal is isotropic, has both elasti-,:; and plastic behaviour and is subject to strain hardening, The boundaries of the plastic region are assumed straight and parallel to each other. The isothermal assumption is justified by the high speed of ~-uttlng. The elastic deformations can be neglec.ted. The parallel shape of. ~he plastic region is confirmed by.observation when the region 'Inuilediately adjacent to the cutting edge is ignored'. The strain hardening is des~::ribed by a power- funcLion which relatesthe shear stresses to the increments of shear deformation. The back ra-ke angle of the cutting tool, the depth of cut, the cutting speed and the mean normal stress a~ the quitting edge are given. "Card 1/3 S/139/60/000/006/011/032 E191/E481 The Stressed and Deformed State in the.Cutting of Metal The constants 4n the strain hardening,function are determine& from experimental data~ The angle between the 11ne of cutting motion and the boundary of plastic deformation is derived from the measured chip contraction. The velocity of displacement of pa%r,~Lzles parallel to the other boundary of the plastic region is derived by a formula quoted from M.I.Klushin (Ref.l)-. The problem consists in finding relations between the stress and ;~itrain components and the given magnitudes. ~The equations of motion are formulated followinz Le--ri and Mizes, (Ref-3). After some transformations, it is found possible to perform an integration of the equations and to obtain at first the relation betiveen the components of slip deformation and.the'rate of displacement, It is shown that a term in the.expression for the shear stress which is due to inertia effects 4-an be neglected in all, practical condations up to a cutting speed of 500 m/min. Eq. (1.21) summarize the solutions obtained. .

The mean normal pressure, which is a.linear functionof the. coordinate parallel to the plastic region'boundary, is superimposed on the abave shear stress component. The expression for the specific plastic work is found, It is shown.that, under the assumptions made~ the nature of the deformed state is not that of,simple slipj as usually assumed, but,a slip flow parallel to.the plasti.:--- region boundary, at,a rate whi-ch depends on the strain hardening function. The deformed state is examined and related to the texture of the chip. There are I figure and 5 Soviet references.
