Vacuum melting and casting plant with preheating of molds for casting superalloys “VIPE-3M”

Модели: VIPE-3M

Appointment

Plant “VIPE-3M” is designed for making equiaxed castings of heat-resistant alloys and steels in terms of mass production.

 Design features

Structurally the plant is made as single-chamber and consist of a vacuum melting chamber, vacuum system, thyristor power source and capacitor bank with dividing high-frequency transformer. The furnace design provides melting of superalloys blocks and pouring of casting blocks of height up to 370 mm and a diameter up to 220 mm. Plant has a modular structure: melting furnaces, molds heating furnaces and crucibles are replaceable.

Advantages of the model

Steel capacity of the plant’s melting crucibles is 15-25 kg. Size of replaceble melting crucibles takes from 40 to 70% of chamber’s volume. Heating of heating molds furnace provides using resistance heaters. Design of the inductor provides rigid fixation of the melting crucible in the inductor. Design of the inductor provides its replacement in 10-15 min. Applied power scheme allows the smooth power adjustment on the inductor of 5 kW. There is an opportunity to one-time additional charging during the melting process.
