TECHNOLOGICAL ADVANCES HELP BOOST OUTPUT -- Moscow, Moskovskaya Pravda,
11 Feb 51
The Moscow Stankolit Plant entered the postwar period with a lower produc-
tive capacity and fewer workers than it had before the war. Finding itself
faced with the task of supplying castings for the rapidly growing machine wool
industry, it drew up a plan which called for an output of castings that would
equal the prewar figure by the second year of the plan, and rise 32 percent
above that by 1950.
Now, the Stankolit Plant. not only supplies machine-tool plants, but must
fill orders for tool and abrasives enterprises as well. The nature of orders
submitted is, furthermore, extremely varied. One plant calls for 50-60 tons
of castings a year, another one will require 500-600 tons, a third will order
nearly 20,000 tons,
The plants placing the heaviest and most important orders are the Moscow
Krasnyy Proletariy Plant and the Moscow Machine-Tool Plant imeni Ordzhonikidze.
Before the war, each of these enterprises put out only a few types of machines:
the Krasnyy Proletariy Plant produced a great number of DIP machine tools, and
the Plant imeni Ordzhonikidze produced turret lathes. In the postwar period,
these enterprises began building dozens of different extremely complex, heavy,
special automatic and universal machines, as well as automatic machine tool
lines. The Stankolit Plant must not only catch up to the production of these
plants, but must overtake it, for the machine-tool plants must have the cast-
ings before they can start to build the machines.
Because of the new situation, the Stankolit Plant, originally set up for
mass production, had to turn to the individual and small-series production of
a considerable number of castings, putting out an increasing number of intri-
cate and complex items. In 1950, they constituted 40.5 percent of the plant's
entire output.

Another problem was presented by the increasing speeds at which new machines
were being put into production at the plants supplied. The cycles for the pro-
duction of machine toils of new types were greatly shortened, with machines which
formerly took 12 years to put into production now going into series production
within 7-8 months. Thus, the Stankolit Plant has had to run its own production
at increasingly faster rates.
Finally, any analysis of the work of the Stankolit Plant must take into
account the sharp increase in machine-tool builders' requirements for heavy
castings. This is an important point, because the plant's shops were set up
for closed production cycles, each of which was designed for output of cast-
ings within a limited weight group.
The need to adapt the plant to the production of a great number of small-
series and individually produced castings called for a considerable effort from
the workers. It can now be said, however, that the plant was successful in meet-
ing the challenge. The plant increased its output of castings 98 percent during
the Five-Year Plan, and not only completely met demands for parts cast from or-
dinary gray iron, but put out hundreds of Was of aLeei caaLiugs (after the pro-
duction of these parts had been established in 1949), as well as thousands of
tons of castings of superhard modified pig iron.
A number of technological measures taken by the plant with the help of its
laboratory played an important role in helping it solve its problems. The chief
of these was extensive mechanization of production processes. The plant built
over 60 units of extra nonstandard equipment, including shot-blasting chambers,
cleaning drums, shakeout grids and riddles, movable furnaces for drying molds,
draw-type molding machines, and a cupola with a generator.
individual production of heave caet.ings was mechanized in shop No 3 with
the installation of a sand slinger for filling large flasks, a unit for surface
drying the molds, and a conveer for feeding molding sand.
A number of parts formerly cast in dry molds were switched to green sand
molds which 'had been dried, Sand slingers replaced hand-molding operations,
and patterns were mounted on plates. Many special fittings were made: flasks,
mold boards, pattern complexes, pins, etc.
To raise the output of molding machines, the design and fittings were changed
in a number of cases, increasing their size while maintaining tht; force weight.
Now heavier molds can be made on these machines.
A great deal of work was carried on in setting up systec.s for the transpor-
tation of molds, parts, sand, and waste. The design of the sand-slinger impeller
head was changed, and shakeout grids of 7.5 tons capacity were installed.
All these measures led to a 25-percent increase in the output of heavy
castings during 1950.
The problem of casting rejects is an important one for any foundry. Many
foundries consider production to be running well if 7-8 percent of the castings
are unsound. For its part,'the Stankolit Plant has met with remarkable success
in the reduction of rejects. Despite the fact that the plant put into produc-
tion 3,376 parts, for which new patterns had to be made, rejects have been
steadily reduced. In the first quarter of 1950, rejects constituted only 6.7
percent of the total output; in the second quarter, the figure was cut to 5.7
percent; in the third quarter, it was only 4,5 percent; and in the fourth
quarter, rejects were only 4.3 percent of the total production,

The quality of sound castings was also improved. While in 1949 only 26
percent of the castings produced were given the rating of "excellent quality,"
65 percent of those produced in the fourth quarter of 1950 were rated excellent.
Now,nearly two thirds of the parts shipped out are primer coated.
One of the most important technological advances in the plant has been the
introduction of high-speed molding and core making. The plant was aided in this
field by the Central Scientific Research Institute of Technology and Machine
Building, which showed the workers how to use the quick-drying molding mixtures
developed by the institute's scientists. Application of the new technology has
made possible the elimination of a number of drying operations in the special
furnaces, and has shortened the production cycle for heavy bench castings by 50
percent.
Recently, the technology of making castings of superhard iron was perfected,
and a group of castings of this material turned out. Efforts are being made to
attai.- more complete combustion in the cupola process by enriching the blast
with oxygen.
The Machine-Tool Institute imeni Stalin has helped the plant develop a high-
speed method of making wooden patterns which has raised the labor productivity
of the pattern makers. During 1950, 105 suggestions for technological improve-
ments were put into practice, resulting in a saving of 1,700,000 rubles,

during the past 5 years have affected its economic indexes. By comparison

means of production, it may be noted that the output of finished products per
1,000 rubles of equipment cost has increased 20,7 percent during the last Five-
Year Plan,
One of the most important nontechnological expenditures went into a special
blower shop, which works on the problem of dust elimination throughout the plant.
Equipment has been built and installed for precipitation of dust, and a method
for removing dust from the castings with wet scrubbers has been developed. A
5-month period of experimentation conducted by the Institute of Labor Welfare
showed the scrubbers to be entirely satisfactory, and in 1951 similar scru'7,bers
will be installed in all areas where much dust is generated, -- P. Kuleshov,

TURN OUT CASTINGS WITH MINIMUM ALLOWANCES -- Moscow, Avtomobil'naya i Traktornaya
Promyshlennost', Jan 51
A new method for casting bronze sleeves has been developed which u;ilizes
a permanent metal mold, called a crystallizer. This mold is surrounded by a
circulating-water cooling jacket.
In casting a sleeve, the mold is first lubricated, and a sand core inserted.
The mold is then swung over a bath of molten bronze, and the open bottom lowered
into the bath, An electric vacuum pump then exhausts the air from the mold, and
the molten bronze is drawn up into it. The mold is then swung away, and the cast-
ing removed.
The sleeves cast by this machine have better mechanical qualities and lower
allowances than those cast by ordinary methods,y~,nus, less subsequent machin-
ing is required, and considerable metal is caved,

TEST PERMANENT MOLD MACHINE -- Moscow, Vechernyaya Moskva, 28 Feb 51
The machine-tool-building shop of the Heating Fittings Plant imeni Voykov
has built many original foundry machines.
The plant has just completed tests on a new machine, designed to turn out
shaped castings in permanent metal molds. It measures 5 meters in.Ldiameter,
and is completely mechanized for all the casting processes. The castings do
not require subsequent machining.
