Abstract
FIELD: metallurgy, particular, methods of manufacture of corundum changeable crucibles for melting steels and high-temperature alloys. SUBSTANCE: manufacture of corundum crucibles includes mixing, for instance, 70% of corundum and 30% of alumina, molding of crucible blank, firing of blank at temperature of 1350-1400 C, placing into induction heater, filling of space between crucible crock and induction heater with refractory powder and compaction with force not exceeding the blank strength; installation of rod of conducting material inside crucible blank, connection of rod to secondary winding of induction heater, and heating of crucible crock in alternating field to produce temperature within 1700-1800 C on internal surface of crucible crock and temperature of 1350-1400 C on the external surface. EFFECT: provision of manufacture of corundum crucibles with high thermal stability. 1 dwg, 2 tbl
