ABSTRACT- A three -stand tolling mill of the MMK was employed during
research i oncerned with the effeci of rolling JR) rate on the
thickness cii a strip JS), the establishment of interrelation of
pressure and pull during cold R. and determination of the sig-
nificance-of longitudinal and transverse thickness variations in
the S. A mathematical relationship is established between the
basic. parameters of the technological process of cold R of a S.
It is established that variations in the tension of the strip mid-
way between the stands of a mill have a decisive effect on the
Card I/Z formation and magnitude of thickness variations in the S.

137-58-6-12155
The Interrelation of the Pressure, the Pull, and the Thi( kness ofa Strip(cont.)
Fluctuations of It rate at the MMK have practically no effect on the thickness
of the S. Variations in the pull produce ihicknems variations in the S equiva-
lent to 0.01-0.02 mm on the average.

ABSTRACT: A photometric study was conducted of the converter flame
(by spectroscope connected to a film camera), and optical
monitoring by photoelectric pyrometer with recording potent-
iometer was performed. In both cases, intensity of emission
was found to increase during the fining period. this being con-
.nected with an increase in the Cu contents of the melt. Max-
imum emission of light was attained during the final 5 to 8
'min. The subsequent sharp drop is apparently to be explained
by the onset of Cu oxidation.

ABSTRACT: Modern toncoptions on the changes In the electron structure
of atoms and their influence on the character of the chemical
bond forces, gained from the ntudy of somi-conductors justify
a more thorough analysis of various phenomena involvea in
metallurgical procesues. In earlier work in this field,rela-
ting to compounds of heavy non-ferrous Wt313, the teaz of
the authors of this paper established tht existence of a tem-
perature correspondenoe in the thaw~ps of the properties
of these compounds and of their components. The aim of
the work described in tiiis paper wap tc study the inter-
relation between the temperature changes and the properties
of copper and sulphur and the propertier of the simple com-
pound Cu28 formed from these. Cxt~,S wa:3 chosen for investiga-
tion due to the fact that it in on-,~ of the basic components

and 79.1% Cu, 20A1761 S (the theoretical composition being
79.8% Cu, 20.2% 8 . In both caaes the composition was in
the range of solid solutions of sulphur in C-a2S. The differ-
ences in the composition of the two apecimens proved to be
of little Importance. The experiments were carried out
mainly with sulphld4 grains of the sizes 0.1,;0 to 0.63 mm.
Oxidation of the sulpbide was carried cut in a vacuum set-
up, a sketch of which is shown in Fle.1, p.BA,, using the
method of circulating air in a closed ayate=, drawing it throu
a layer of the charge which is heated to a certain tem-
perature; the gases obtained after drawing off the air through
the charge were caught by a device in which cooling by means
of liquid nitrogen was applied for the parpeae of freezing out
sulphuroud scid.anhydride and sulphuric anhydride, According
to Averbukh 'B.D. (Ref.7) the quantity of forming sulphuric
anhydride under these conditions is vory low and, therefore,
was not determined separatelZr. "A"he Investolgations were
carried out with a const-ant initial air pl-en3ure in the system

speeds of oxidation of the copper aulphide at critical tem-

tuationa in the oxidation opeed r-?ach 20 to 30% and take
place in the temperature range 5 to 150C. On the basis of
study of the oxidation isother-ma, the degree of utiliontion
of the ox:1-gen and the yield of sulphur-:ius acid anhydride and
of the influence of the oxidation duration, the conclusion
is arrived at that the determining fac!tor in the process of

there is a direct relation and a texperature correspondence
between the chw4os takimg place in various metal compounds
and the changes in the properties of the individual
elements forming these compounds. In this paperl the
authors aimed at verifying this conclusion for iron oxides
and thus to try and explain szonalous phenomena taking

9estigations nearer to industrially used materials, the
authors used in the experiments magnetite and not pure,
oxides. The composition of the ore was as follows: 51.1%

The ore was heated to the desired temperature in vacuum
(10-2 to 10-3 mm HS). 7ollowing that, a quantity of
hydrogen was introduced which was equal in every case ,
maintaining the reasuro constant. The speed of reduction
was judged fro& the consumption of hydrogen in the closed
system which was measured *Very minute. Nvery three

the temperature was readjusted and the gaseous phase

of successive measurements, carried out at 3 sin intervals,

each temperature the *xperlments were carried out with a
fresh ore specimen. Since the aim of the work was to
elucidate the existence of a relation between the changes
in the.properties of the Iron, at temperatures at which it
is known that phase transformations take place, and the
kinstics of reduction of iron oxides under equal conditions,
tbeinvestigatione.were carried out in the temperature
range 700 to 910 0. In this temperature range magnetic
as well as polymorphous Sransforzations take place In the
iron at 768 and 906-910 0, respectively. The speeds of
reduction of magn tits, e3q~ressed in terms of hydrogen
consumption during the firist 3 min as a function of the
temperature, are grqhed in Figure 1. It can'be seen that
the graph contains several anomalous sections. The
obtained results justify revision of certain views expressed

on the kinetics of reduction of iron oxides. In the
first instaws, it is quite evident that sintering
phenousna changes in the porosity and recrystallisation
of the AtUded substances and in the reaction products,
changes of speed of diffusion and the speed of chenical
-reactions do occur in the course of variation of the
temperature during reduction of the ores and of iron
oxides. The.most plausible explanation of the anomalous
phenomena in the processes of reduction is based an the
chanees of the state of the Iron stons as a function of
the isiperature, particularly as regards phase trawAbr-
nations. The obtained results (Figure 1) indicgt* that
the jumps in the speed of reduction at 752-756 C
correspond to the magnetic transformation of the irons

The following conclusions ars arrived at:
1) The speed of reduction of magnetite with hydrogen
decreases in jumps and then again increases within narrow

ABSTRACT: In investigating the beat exchange processes in blast
furnaces, the charge of which contains ores and fluxes,
it was established that the curve of temperature
distribution along the height of the furnace is S-shaped
(Refs 1-8). It is characteristic that in the central
part the temperature in the vertical direction changes
very little and is mainteined spontaneously in the
neighbourhood of 800 to 900 0,; the difference between the
temperature of the gases and of the charso assumes in
this region the minimuis value of 5 to 10 t;, The presence
of this quasi isothermal zone, referred to an the no-load
reserve zone or the zone of moderate temperatures, was
considered as being a stable typical relation. However,
recent experiments by 3. N. isbarykin and F. A. Yushin
(Ref 9) have shown that if fluxed agglomerate is sAelted
C&rdl/3 without _aharytng ore andL lAmestone, the previouzly

mentioned temperature distribution is not maintained and
the temperature curves show two to three isothermal
breaks, The cause of these has not boon clarified. On
the basis of data obtained from practical experience and
analysis of the thermal balance of blast furnaces it can
be concluded that in the reserve zone of the bl"i furnace
a considerable A-*jmw& of reduction processes td= pbw and alm
an intensification of the processes of host exchangsibiehis
brought about by the isothermal processes. From the
correspondence between the texperatures, of the Change in
the properties of iron and its oxides and the temperatures
at which the break in the temperature rise occurs in blast
furnaces it can be concluded that the appearance of
isothermal zones is due to transient states of iron and
its oxides, i.e. it is due to the nature of the main
reacting substances.
