METHOD FOR RESTORING WORKING WALLS OF CRYSTALLIZER

摘要

FIELD: metallurgy. ^ SUBSTANCE: working walls of crystallizer are restored without dismounting them. At first condition of working surfaces of walls is detected. If lower portions of surfaces of narrow and wide walls near angles of crystallizer are worn and central portion of narrow walls are not worn, shot blasting of worn surface is performed. Then coating is applied onto said zone by gasothermic deposition. Residual wear degree is no less than 0.5 - 0.6 mm. If central portion of narrow walls is not worn it is provided improved strength of deposited coating. ^ EFFECT: enhanced strength of deposited coating. ^ 2 ex
