INDIFFERENCE SHARED BY MINISTRY, MAIN ADMINISTRATION -- Leningradskaya Pravda,

The manufacture of blading constitutes about 25-30 percent of the total
volume of work involved in building a steam turbine. The blades are milled
from bar-shaped billets, with 80 percent of the high-cost alloyed steel going
off into chips. It is, therefore, clear that precision casting and precision 50X1- H U M

Over a year ago, the Orgtyazhmash Institute helped
ith etLeningrad Ekonomaof
zer Plant to work out the technology and draw up plans
a precision-casting section. The directors of the plant, however, do not yet
deem the section of sufficient importance to make room for it.
The situation is not much better at the Leningrad Plant imeni Lenin. Here
the plant laboratory worked with representatives of the institute, and developed
the technology for precision casting of stator blades for a turbocompressor, as
well as a number of other turbine blades. An experimental precision-casting
section was established, and it appeared that even under conditions not adaptable
to mass production, the cost of blades was being reduced two or three times,
while the coefficient of efficiency of metal increased five times, and machining
work was cut seven or eight times.

It was obvious that tie pre_ clon method warranted transfer from the
pla
experimental to the production stage. But neither the to nt director,thiskit.,
nor the chief engineer, Kholin, showed any great
change, despite the insistent offer of further help from the Orgtyazhmash
Institute,
In July 1950, the institute prepared a dra?t order in accordance with the
casting Heavy Machine Adminiing that of nthe

directors, requesting; a de-_ Lsien within. lu days, At the end of 10 months,
however, ro one had c~ade a decision on the project, and no one is doing any-
thing about introducing precision, casting into production.
How is it possible that the draft order was forgotten in the main adminis-
tration and in the :rinistry: The answer 'lies in the fact that their leading
officials share the conservative attitude of the plant directors. Berezin,

MODERNIZE OLD DESIGNS -- higa, Sove',skaya Latviya, 9 Jan 51
The Riga Turbine Machinery Plant made Great strides during the postwar Five-
Year Plan. High-speed metal cutting was introduced, Stakhanovite methods were
applied, and high-duty attachments and tools were made in the plant shops.
Labor productivity rose sharply as a result of these measures, and the 1950
plan was fulfilled ahead of time..
Work has recently been going on under Chief Engineer Orlov involving inno-
vations in metallurgy and standardization of parts, both measures being comple-
mentary to the over-all effort to modernize the design and simplify the construc-

The plant foundry is now producing the sups he,-6 pig iron uevel.oped by
Stalin Prize winner Mil'man. This remarkable alloy has superior casting quali-
ties and is easily machined. It is estimated that parts made from it would cost
35-40 percent less than if they were made of steel.
At present, the plant is utilizing so-called modified pig iron, which is
ast
much more durable than grey iron. Hydroturbine wheels, formerly made fwcast
steel, have been redesigned, and are now made of the modified pig iron,
lowers their cost 30 percent.
Covers for turbopump oil-c,nlerc are now made of cast iron instead of
from miller. steel. Turbopump drainage manifolds are made of steel instead of
red copper, a change which is saving kilograms of valuable metal for each
machine. Some precision casting is being carried out.
Considerable standardization of fastening parts of the machines has been
effected, reducing the number of different component items 25 percent.
