Abstract
Experiments were performed on processing briquetted and non-briquetted shavings of Kh18N10T stainless steel and 07Kh12NMBF (EP609) and KhN70VMTYuF (EI617) heat-resistant alloys in induction furnaces and electroslag furnaces. It is shown that the most preferable is the technology of simultaneous remelting of a consumable electrode from lump wastes and shavings in an electroslag crucible furnace. In this case, at melting in 120 kg furnace at the amount of shavings fed for melting, equal to 45…55 % of the total melt mass, the specific power consumption is equal to 0.55…0.65 kW/.h/kg, productivity is 130…160 kg/h, and burnout losses are not more than 1…2 %. At electroslag crucible melting it is possible to actively conduct such metallurgical operations as refining, modification, alloying and deoxidation that allows producing high quality metal.
