THE BNCONSTRUCTEN OF. A USSR, WHEEL ROLLING. SE .
In the reconstruction of the wheel-rolling shop at the Metallurgical
Plant imeni K. Libknekht in Dnepropetrovsk, approximately 3,000 tons of
industrial equipment were assembled, a considerable part of which had to
be rebuilt. Expenditures for this type of repair constituted 47 percent of
the total cost of the machine assembly work which was done by an sdr inis-
tration of the Soyuzmontazhstroy (All-Union Assembly and Construction)
Trust.
The shop was rebuilt in the following order: ingot-cutting, furnace,,
press, and rolling divisions; the rear section, and the hydraulic accumu-
lator station. As soon as the completely destroyed accumulators were re-
.moved, an automatic pneumatic-hydraulic. installation was. assembled.
The equipment of the main press and rolling divisions consists of
(a) three steam hydraulic presses --,3,000, 7,000, and 2,500 tons --
equipped with intensifiers with a working pressure at 400 atmosliherea;; (b)
a wheel-rolling mill; and (c) auxiliary machines -r gantry and bracket
cranes, compressors, pumps.,;, etc. The 2,500-ton press was completely de-
molished, while the and 7,000-tbn presses were only partially
damaged. The rolling mill, although not damaged, was somewhat worn out,
so that its parts had to'be almost completely replaced.
The Ural;He&vy-Machine Building Plant produced the necessary parts
for the 3,000- and 7,000-ton presses as well as a new 2,5000ttpn presg,
intensifiers for hll three presses, and.the hydraulic drives.
When the equipment of the.ingot-cutting division was put into oper-
ation, it consisted of th1 two old ingot-cutting machines which were com-
pletely rebuilt on the spot, ands number of new machines, called "Krasnyy
proletariy," built by the Kramatorsk Machine-Tool Building Plant, the
first of their type built by the Soviet machine-building industry. Other
equipment of this division includes:,'an ingot breaker -- a hcizontal 200-
ton hydraulic press -- ingot cars, cranes, and other auxiliary equipment.
A second ingot-breaker should be installed in the future.

The hydraulic accumlator station, which supplies the press with
water at a pressure of 160 and 60 atmospheres, consists of-the follow-
ing equipment:.for hydraulic and three plunger pumps with.pressure up
to 200 atmospheres, two centrifugal multistage pumps with pressure up
to 60 atomospheres, a group of hydraulic accumulators at 60 atmospheres
(one water and two air tanks), a group of byy4raulic accumulators at 160
atmospheres (two water and six air tanks). The entire water supply
system has been made completely automatic.
Assembly, work was begun as soon as the foundations for the presses
were ready. The building of the,: foundations under the iintensifiers.?
and the roof laying and other construction ,joys were done simultaneously
with the assembly of the presses. The installation of the foundations for
the presses was done in accordance with technological demands, accurate
within 0.05 millimeter per one running meter of foundation. Inspection
of the installatiom?was dor^ by a control level accurate within 0.03 milli-
meter: per running meter, while deviation was permitted at only one sec-
tion of the level. The foundation was made of quick-drying cement so
that assembly could begin on the third day after pouring.
Parts of the main units of the 7,000-ton press, including the slid-
ing crosshead, the foundation, and the architrave, were joined together
by 125-millimeter-diameter bolts. Once the foundation was }Milt, the.
sliding crosshead was assembled on it and the main columns were installed
through the openings in the crosshead. A railroad crane was used to in-
stall the 30-ton columns, an extremely complex procedure since the struc-
ture of the shop and the previous,y installed columns hampered the movement
of the crane boom in handling such large columns; the crane had to be
moved to a new position each time one column was to be installed. The
columns had to be installed with particular care since the slightest de-
viation -would cause the bushings of the crosshead to jam on the columns.
The most complex operation in assembling the 7,000-ton press was
the installation fr m above of the columns-of the architrave, the parts
of which weigh 50 tons each. The bushings of the crosshead were put in
from below; so that the assembled 250-ton crosshead had to be raised
2 meters..
All that was preserved of the 200-ton wheel-rolling mill were the
main bed, reducer with underframe, and the plate of the vertical shaft
bearing. All other parts, are new. But the preserved parts were somewhat
misshapen from wear and long exposure to the elements, so that their final
installation could be done only after complete assembly of the mill and
alignment of the cardan shaft, the bevel gear drive, and the vertical
shaft. The assembly work was considerably complicated by the lack of
necessary parts, the production of whi-dhWas completely unsatisfactory be-
cause of the small capacity of the machine shop. It was not until the
end of the assembly work that the problem of sending out orders was solved.

The assembler of the accumulator station units was completed in an
extremely a*iort?time.. The housing of the station was rebuilt. It was
necessary to remove a large number of ald-"oundations, thus delaying
assembly work for 2-months, during which time"ter'.s of the pumps were
made.. Inspection of. the pumps revealed the need for much repair work,
particularly new lining of all crank and crankpin bearings of the pumps
and all bearings of the reducers, for which one ton of B-83 babbitt was
necessary.
.The accumulator installation, located in a special annex, consists
of' 9 hydraulic tanks, of chic: 11- are for the wheel-rolling shop'nnd
eight for pumps.of another stop schedu'led to be rebuilt after the wheel
shop. After the tanks were installed, they underwent hydraulic testing
at one and one and a half working pressure, i. e. at 90 and 240 atmos-
pheres, and were inspected by Kotlonadzor (Boiler Inspection).
.The automatic control equipment for the station was assembled simul-
t& 19th with the installation of the basic equipment. -The interlink-
ing of the electric and hydisUlic.apparatus makes the operation of the
pumps completely automatic.
