FIELD: metallurgy; restoration of working surface of crystallizer walls without disassembly of it.
SUBSTANCE: method of restoration of crystallizer walls made from copper and its alloys includes making notch, 0.5 mm deep at depth of wear of working surface no less than 1.0 mm. Then, working surface at depth of wear no less than 0.5 mm is subjected to shot-blasting after which precoat of thermo-reactive material, 0.1-0.2 mm thick and working layer of wear-resistant material are applied by gas thermal spraying. Depth of residual wear is no less than 0.5 mm.
EFFECT: enhanced resistance of coat.
