Intermediate frequency electric furnace development in modern casting production

Modern medium frequency electric furnace machinery manufacturing technology and the rapid development of metallurgical technology on casting quality, elaboration, and energy saving requirements, such as high performance of ductile iron castings, vermicular graphite cast iron and the application of aluminum alloy castings, high quality castings, makes the induction furnace is increasingly important in the position in modern casting production. All made and new foundry casting workshop, the fuss made or acquire induction furnace is usually in the first place. As a result, "" in the selection of induction furnace is a subject worth attention.
Efficient, reliable and flexible operation of the intermediate frequency induction furnace of the development of manufacturing technology in vigilance and establishing the important position of induction furnace in foundry production process has played a role cannot be underestimated. From the bottom and has nearly a century of compared to traditional power frequency induction furnace, whether from the technical performance and job performance or from the aspects of investment, medium frequency induction furnace is the undisputed dominance. That makes it rapidly changing since the late 80 s of last century is widely applied in developed countries such as Europe, America, basically replaced the traditional power frequency induction furnace in our country has gradually disappeared from the market, the existing power frequency induction furnace in foundry are gradually replaced by medium frequency induction furnace in this technical improvement.
