FIELD: ferrous metallurgy. SUBSTANCE: invention concerns hot repair of lining of converter in state of operation. Converter with left, after tapping off liquid metal, liquid slag is turned relative to vertical axis towards taphole to angle 90-125 deg, after which gas is fed through taphole with rate 0.08-0.25 cu.m/min per 1 t. Lining is then coated with slag skull. Possible also is multiple alternation of slag skull application onto lining and rotation of converter in opposite direction. EFFECT: simplified process. 5 cl, 1 tbl
