"Zbur Tekh Fiz" Vol 22, No 10, PP 1556-1564
Discusses mechaLiSM of breakdown if ceramics at
high frequencies. Assumption of "thermotonization"
character of breakdown of porous dielectric makes
it possible to establish a connection between
physicomechanical properties and electric strength.

The author reports on experiments on 321 healthy young persons re-
W ding the resistance of the human organism to disease In the polar re-
gions where, according to a number of physicians who have worked in
northern latitudes, certain diseases have specific characteristics. The
young people were divided into three groups, one of which was tested
dwing the polar night, the other during the polar day, and the third
during both the polar night and the polar day. The tests consisted of
Injecting intracutaneously one ml of a 1 100 dilution of "so-called
antihuman serum" furnished by the MIcroblological Department of the
Institute of Experimental Medicine, Academy of Medical Sciences USSR.
Normal rabbit serum was used as control.

Experiments showed that planing the slabs on both sides reduced variations in
thickness up to approximately 20%. The lubricating interlayer has a low
thermal conductivity and impedes heat exchange between the upper and lower
parts of the packet during heating which prevents temperature equalization.
This CaUSOS variations In the thickness of the finished sheet. It was found
that the absolute variation In thickness increases with the thickness of the
sheets. The relative variations in thickness are approximately the same for
sheets of an thicknesses with the exception of 16 mm sheets for which variations
are somewhat lower. In 80% of the Cases. deviations from the nominal thickness

more faVOILrable distribution )t the roll pressure along the pass
is obtained if instead of a 4-zone pass a tapered pass calculated
from tile formulae (1) and (2) is used. Since tile maximum roll
pressure in a tapered pass Ls 1. 5 times lower than that in a
4-zone pass, the introduction of the former in industrial pract ice

(10-80 reciprocal revs/min), the roll pressure remains practically
constant. (6) Best results (lowest roll pressure) are obtained
when an oil/graphite mixture is used for lubrication. However,
this lubricant is difficult to remove from the finished product,
and the application of emulsol or solidol is recommended instead.

T EXT: Many of the mechanical failures, encountered in the
cold-reducing process (seizure of the stock, bending of the rod
supporting the mandrel, excessive wear of various parts of the
feeding mechanism) are caused by axial loads which, in addition,
constitute a factor limiting the protective capacity of the mill.
It was for these reasons that the present investigation,
concerned with axial loads in rolling non-ferrous metals and
alloys, was undertaken. The measurements were carried out on
cold-reducing mills Xfl7-11'/211 (KhPT-11/2") and XnT-2-1/2"
MPT-21/2"), used for rolling copper and brass tubes. The
axial loads, acting directly on stock, were measured with the aid
of carbon pressure gauges, mounted in a special dev ce attached to
the end of the stock. In the case of mill 1-101 1 )2, only the

compressive loads were measured; the device used during rolling
on mill KhPT-21/2" was designed to measure both compressive and
tensile loads. A general view of this device is reproduced in
Fig.1, which shows a cylinder (1) to which the stock (2) was
rigidly attached, and flanges (3) and (4); the compressive loads
were measured with the aid of three carbon gauges (5), similar
gauges of the membrane type having been used to measure the tensile
loads. The electric pulses generated by the gauges were recorded
with the aid of a magneto-electric oscillograph 11o6 -14 (POB-14).
In addition to the axial loads, the roll pressure was also
determined. In the case of mill KhPT-1-1/2", the measurements were
carried out during rolling of copper and brass tubes through six
different passes. Mill KhPT-21/2" was used to study the
variation of axial loads during rolling of brass tubes through a
tapered pass (61 x 6 - 36 x 3 mm) and through a 4-zone pass
(61 x 6 - 38 x 3 mm). Some of the typical results are reproduced
graphically. In Fig.2, the roll pressure, P M (kg, left-hand
scale) is plotted against the distance, x (mm) from the leading

end of the pass, curves I and 2 relating to the forward and
reverse movements of the rolls respectively. Similarly, curves
3 (forward movement) and 4 (reverse movement) show the variation of
the axial load, Q (Icg, right-hand scale). The results,
reproduced in Figl, relate to copper tubes rolled on mill Khjyr-lz'"
through a Pass 40 x 3 27 x 0.8 mm, the other rolling parameters
being po (elongation) 3.9 and m (feed) = 8.3 mm. The results
for brass 11-66 (L-66) rolled on mill KhPT-21/2" through a 4-zone
pass 61 x 6 - 36 x 3.0 mm (iio = 2.9, m = 4 mm) are reproduced in
the same manner in Fig-3, except that in this case P~ is given in
tons. In Fig.4, the axial load Q -L (kg) is plotted against the
distance x (mm) from the leading end of the pass, curves I and 2
relating respectively to the forward and reverse movement during
rolling of brass L-68 through a tapered pass 61 x 6 - 36 X 3 111m
(ilo = 3.5. m = 4.0 mm). The combined effect of' the variation of
feed, m, and elongation, pot on Q-F (kf) during rolling of
copper (reverse movetnent) on mill Khpll,-l /2", through a pass

3 relating to Po = 3.0, 3.9 and 5.6 respectively, see Fig-5).
In Fig.6, QZ (kg) during rolling of brass L-68 on mill KhPT-11/211
through a pass 36 x 3 - 24 x I mm (~Lo = 3-9) is plotted against m
(mm), curves I and 2 relating respectively to points at a distance
of 154.7 mm from the leading end of the pass (forward movement) and
126.7 nun (reverse movement). In the final experiments, the effect
of various lubricants on Q5 was studied. The results, obtained
during rolling of brass L-60 on mill KhFIT-11/2" through a tapered
pass 36 x 3 - 24 x I nun (40 = 3.9, m = 8.3 mm), are reproduced in
Fig-7, showing the variation of Q-Z due to change of the
lubricant, curves I and 2 having been constructed for the forward
and reverse movement of the rolls, and the experimental points
relating to an oil/graphite mixture (open circles), solidol (full
circles), emulsol (full triangles), and mineral oil (full squares).
The main conclusions reached by the present authors can be
summarised as follows. (1) In analogy to the roll pressure, the
axial loads during cold reducing of tubes vary along the pass.
The axial loads during the reverse movement are considerably higher

than those during the forward movement rolls, constituting 8-loo,,o
of the roll pressure in the former, and only 2-5-6%' i~ the latter
case. If, therefore, seizure of the stocIr occurs, it probably
takes place during the reverse movement of the rolls.
(2) Two-fold increase in the food incronses the axial loads
1.3-1.8 times; a similar increase in the wall thickness of the
stock increases the axial loads by a factor of 2.3.
(3) Minimum axial loads are ensured by using an oil/graphite
mixture for lubrication; mineral oil. used for this purpose,
raises the magnitude of the axial loads to its maximum.

stock (33.2 outside diameter 3.0-5.2 nun wall thickness) was rolled
to the following final sizes 23 x 0.75. 23 x 0.83, 23 x 1.0,
23 x 1.1, 23 x 1 5, and 23 x 1.75 mm. Both the roll grooves and
inside walls of the tubes were lubricated with mineral oil. The
magnitude of feed was determined from the number of reversals per
100 mm of the length of the stock rolled. Owing to the
difficulties encountered in measuring the pressure at normal
rolling speeds a speed of 10-12 reciprocal revs/min was used in
the experiments. In addition to the specific pressure, the total
roll pressure was measuied with the aid of a gauge accommodated in
the roll housing. Preliminary to experiments proper. a formula was
derived for the critical angle, P. in the plane of the groove
