锻造分为模锻、自由锻2种形式。模锻主要用于汽车零部件、工具、轴承环等小型零部件的锻造加工。感应加热具有加热速度快,工件不易氧化等优越性,故迄今汽车零部件、工具、轴承环等小型零部件的锻造加热多采用感应加热方式。鉴于节能、节电的目的,最近日本大阪互斯株式会社成功地开发了可
Forging into forging, free forging two kinds of forms. Forging is mainly used for automotive parts, tools, bearing rings and other small parts of the forging process. Induction heating with heating speed, the workpiece is not easy to oxidation and other advantages, so far auto parts, tools, bearing rings and other small parts of the forging heating induction heating method to use more. In view of the purpose of saving energy and saving electricity, Osaka Shisui Co., Ltd. of Japan recently successfully developed
