摘要： PROBLEM TO BE SOLVED: To provide a blast furnace main trough, which can appropriately inhibit local erosion from occurring on the internal surface of the trough in the vicinity of a boundary between slag and a gas phase.
SOLUTION: This main trough has a gas supply means (A) which is arranged at an inner side of the trough and supplies nitrogen gas and/or an inert gas so as to form an atmospheric part (x) of the nitrogen gas and/or inert gas on at least a slag wetting part 6 of the inner surface 5 of the trough, or sprays the nitrogen gas and/or inert gas onto at least the slag wetting part 6 of the inner surface 5 of the trough. The main trough can supply the nitrogen gas and/or inert gas of sufficient quantity and concentration to the slag wetting part 6, and accordingly provides multiplex effects of sufficiently lowering the oxygen partial pressure of the gas phase which faces the slag wetting part 6, thereby inhibiting the supply of oxygen from the gas phase to a refractory side, and besides decreasing the dissolution rate of the refractory into the slag, which appropriately inhibit the local erosion in the vicinity of the boundary between the slag and the gas phase.
