Induction heating. Feasibility and prospects of application in processes of special electrometallurgy./Part 2. Methods and equipment for induction melting of metals at melt contact with a crucible wall

摘要

Review and analysis of capabilities and basic technical characteristics of channel- and crucible-type induction furnaces used in industry for melting metals and alloys are presented. Specifics of operation and design of these units are outlined. Technical characteristics of AC plasma-arc heaters of 300 and 450 kW capacity, developed at the E.O. Paton Electric Welding Institute of the NAS of Ukraine for intensification of melting in open and vacuum-induction furnaces with a crucible capacity of not less than 0,1 t, are described.
