APPLICATION PROCESSES FOR PLASMA FURNACES WITH GRAPHITE CATHODE FOR MELTING OF NONFERROUS METALS

摘要

The results of investigations devoted to melting of chromic bronze, nickel and nickel base alloys in plasma furnaces with tungsten cathode, executed by 《Tsvetmetobrabotka》 institute, are presented. The conclusion about economical expedience of usage the plasma furnaces with graphite cathode for melting of nonferrous metals is made on the base of analysis of technical, technological and ecological features of these furnaces. It allows to expand usage of scrap and chips for production of quality alloys with better technical and economical melting parameters.
