Abstract
유효수명이 길어지고, 가수누출이 없는 용융금속용 가스분사노즐이 제공된다. 이러한 가스분사노즐을 수리하는 방법도 제공된다. 가스분사노즐에는 좁은 직선천공이 뚫려있는 내화블록과 이러한 직선천공내에 활동적으로 배치된 소형 금속관이 포함되어 있다. 가스분사노즐이 부분적으로 소멸된 때에는 소형 금속관을 위쪽으로 이동시켜서 노내로 돌출하게 하고, 소멸부분을 내화재로 충전한다.There is provided a gas injection nozzle for a molten metal in which the effective service life is prolonged and there is no water leakage. A method of repairing such a gas injection nozzle is also provided. The gas injection nozzle includes a refractory block with narrow linear perforations and a small metal tube that is actively disposed within such linear perforations. When the gas injection nozzle partially disappears, the small metal tube is moved upward to protrude into the furnace, and the extinction portion is filled with the refractory material.
