TITLE: On the Work of Friction During Rolling (0 rabote treniya pri prokatke)
PERIODICAL: Sb. statey. Chelyab. politeXhn, in-t, 1958, Nr 8, lip 58-65
ABSTRACT: The author criticizes the formulae developed by Vereshchagin, Petrov,
Bayukov, and Chekmarev for the purpose of calcutating the work
against friction (Fr) forces (F). Starting from the assumption that
the specific pressures are distributed uniformly along the arc of con-
tact, the author derives a formula for the relative slipping of metal
over the rolls and for the work done against the Ft F's in the lag and
the lead zones, as well as in the entire contact area. The magnitude
of the Fr is determined. A number of curves are given representing
the work done against the Fr F's as a function of the critical angle y
at various coefficients of Fr and under particular conditions of rcIling;
under conditions when the coefficient of Fr is > 0.1, the work done
against Fr accounts for the greater portion of energy losses-A
computation of the effect of spread on the work done against Fr is

ABSTRAM A new method of computing the working rate of reversing mills
is presented which is bas6d on the graphical interpretation of
the rolling process in such mills, and on the main principle
that the areas of portions.of the graph (Pigure 1) corre-
sponding to the machining time are directly proportional to
the length of tha rolled strip. The correctness of thla
principle which vas first developed by A.I. Tselikov Z_Ref 2_79
in confirmed ani 'lasic problems-bf rolling on reversing mills
are analyzed with the use of the proposed method. Formulae
are given to calculate the machining time of the pass, duration
of the cycle of roll revolution and the optimum ratio for the
rates of the grasp and release of the strip* Computation of

ABSTRACT-1 The well-known Fink formula for the determination of the power (,P1
of rolling (R) cannot be considered sufficiently accurate because it
fails to take into consideration the fact that the P of R is a function
of the magnitude of the critical angle N , i - e., of the forward slip,
and because it completely disregards the effect of spread in the
strip. Data of an investigation were employed in deriving formulas
for the displaced volume of metal, the quantity of work, and the P of
R, due allowances being made for the phenomena of spread and for-
ward slip of the sirp: an analysis of the effect of the indivdual fac-
tors on the P of R is also given. The formulas derived have the

ho the initial height of the strip; hl the final height of the strip; v the peripheral
velocity of the rolls; t the time required for R of the strip; and -y the critical
angle. These formulas may be employed in the determination of the work and the
P of R of any structural shapes. They also make it possible to establibli by which
factors and to what extent the P of R is affected. It follows from the last formula
that an increase in the forward slip results in all instances in an increased P of R.
This may be explained by the fact that as the angle -y is increased, the area C. It
[Transl. Note: Russian original reads becomes greater and, as a result,
the quantity of metal being drawn into the rtlls (where it is reduced) per unit
time is also increased. Essentially, the effect c,,' spread manifests itself in the
fact that as its intensity is increased the area of the critical cross section u.-V
increases together with the amount of metal deformed in one second. As the diam-
eter of the rolls is made larger, the length and, consequently, the volume of the
contact area is increased. Under conditions of constant relative reduction ho/hl,
this results in an increased volume of metal displaced as well as in an increased
P of R. The P of R increases also with increasing thickness hl of the strip. The
physical meaning of this regularity in behavior lies in the fact that, while the
volume of thecontact area increases as the h, is increased, the 'Ogeho/lil grows

PERIODICAL: Zavodskaya Laboratoriya, 1958, Vol. 24, Nr 1. pp. 88-89 (USSR)
ABSTRACT: In this paper a now method of determining tho wear of grooves of
rolling shafts is recommended. For this purpose two works templates
were rivetted together in such a manner that a distance of 6-8
rema.1ned between them. On the surfawof one of the templates
linen were drawn symmetrically and parallel to the axis of the
template, after which they both received a coating of paint. In
tho inner diameter of the grooved part of the roll a layer of
"plantiline" was applied in such a manner that it filled the
grooved profile at one part of the shaft, so that it was located
3-4 rin higher. At this point the aforementioned double template
was pressed in in the direction of the axis of the shaft. The
11plwitiline" entered the space between the two templates. The
double template was then removed from the shaft and was filled
with "plastiline". The extend to which this filling protruded be-

ABSTRACT; This Is an example of analytical study of upsetting the
strip in presence of external parto (not deformed)-
-rigid ends. In author's previous work various problems
of uniform (over volume of the body) deformation were
solved by application of the principle of a minimum of'
full energy of deformation and the law of preservation
of energy.. During uniform deformation, the mechanism
of changing the shape Is fully determined by one
variable parameter (*V ), and the condition of a minimum
of full energy of deformation is reduced to the
usual condition of a minimum of a function of one

TEXT: The basioregilarities of the continuous strip rolling process
are mathematically analyzed considering the stands, strip and electric drit!i)
of an integral system under the eff3ot of the energy conservation law. Equa-
tions of the strip tension, rolling moment and power, and lead are dorived and
suggested for use in the analysis and oalculation of automatic control systems
for continuous rolling mills. The continuous rolling process with tension
(with reels) had been disoussed in detail in the author's papers(Ref. 1: 0 vli-
