摘要： The present invention relates to a method of manufacturing a slag discharge door, which is provided separately from a molten-steel discharge opening in an electric furnace and opens and closes a slag discharge opening for discharging slag. The method of manufacturing the slag discharge door, which moves up and down on the slag discharge opening to open and close the slag discharge opening, includes the steps of: forming a door body by forging, forming a coolant passage, a coolant inlet, and a coolant outlet in the door body by drilling, and then finishing a passage that blocks a portion that is open toward an outer surface of the door body.

摘要： A tuyere for an iron making furnace, including a body unit having a blast passage passing through a central axis thereof, wherein the body unit includes: a frusto-conical body having a main body cooling passage; and a protruding part protruding from the body, wherein the tuyere further includes: a cover unit combined with the protruding part and defining a tip body cooling passage between the cover unit and the outer circumferential surface of the protruding part; and an outer unit combined with the cover unit while surrounding the cover unit and defining an outer cooling passage therein. When the outer unit is partially damaged, although the cooling water supply to the damaged part is cut off, the function of the tuyere can be continuously performed both by the remaining part of the outer unit and by the body unit, thereby providing a tuyere having a lengthened life span.
