Smelting
Smelting line is composed of assorted vacuum induction furnace (1 ton to 6 tons, 12 tons)， various types of ESR (0.5 tons to 20 tons), VAR (5 tons to 12 tons), Electroslag furnace protective atmosphere, EB, PAM. These equipments are representative of the contemporary world's most advanced level. Among them, PAM is the only one used exclusively for the aircraft engine rotating parts of the key materials in the production test and industrial equipment.
