The Special Design Bureau -3 (part of the military-industrial holding company "Kingisepp Machine-Building Plant") has created a method for casting mold tooling. The technology was successfully used in the production of gas turbine engine blades for the order of LLC "SEMAKS METALL". This was reported by the press service of the enterprise.
The production task was to design casting technology. For this purpose, they were created from a nickel-based alloy ZhS6U. It cannot be remelted in an induction furnace during open melting.
A casting technology was developed for the vacuum induction remelting method in a specialized unit in the Zimitsy casting shop. The castings were made without a single defect and shipped to the customer.
Turbine blades are used for the operation of gas turbine engines. The compressor compresses the air, it is fed into the combustion chamber of the gas turbine unit, mixed with natural gas and expands. Then the air enters the blades and creates pressure on the blades. This forces the shaft connected to the generator to move.
Earlier www1.ru reported that a new complex for assembling high-power gas turbines GTE-110M will be built in Russia.
