Abstract

Abstract: Shanghai No.5 Steel Co., Ltd. has recently introduced a set of 5-ton protective atmosphere electroslag remelting furnace and a set of lO-ton helium-cooling vacuum arc remelting furnace,both of them are the first one of its kind in China. With these equipment, remelting processes about alloy GH4169, GH2132 and GH738 were researched, the process of producing alloy GH4169 by VIM+ VAR + ESR triplex-process was developed, and their effects were discussed.

Key words: superalloy, argon shield, ESR
