FIELD: ferrous metallurgy.
SUBSTANCE: invention relates to repair of blast furnace main discharge chute lining. Melting products are lowered from the chute, cooled and repaired. In the interval between repairs of the lining with pouring of concrete, local repair of the slag belt of the main chute is additionally performed with a ramming mass without disassembly and removal of the cast-iron belt concrete lining of the main chute.
EFFECT: invention is aimed at increasing the overhaul period, increasing the resistance of the refractory lining, reducing the consumption of refractory poured concrete per ton of cast iron.
