FIELD: metallurgy.
SUBSTANCE: invention relates to metallurgy, namely, to furnace for sintering of agglomeration charge on moving grate trolleys. Furnace comprises three roof steel air-cooled burner panels protected by refractories, used for heating and air supply to burners and serving as structural supports for burners and lining. As protective refractory there used are blocks made of light-weight fibrous refractory material, installed tightly to roof steel air-cooled burner panel, and burners are separated from blocks by metal heat-resistant casings, which protect light-weight fibrous fire-resistant material of blocks from erosion action of flame.
EFFECT: invention makes it possible to repair the furnace by replacing any of three panels with broken lining without long-term stoppage of the unit for repair.
