| Zusammenfassung: | To quickly and surely execute measures for preventing an unexpected event due to in-furnace gas entering from a damaged part of a flow path when the flow path is damaged.SOLUTION: In a treatment method when a flow path 2 among a plurality of flow paths 2, 3 is damaged in a tuyere 1 having the plurality of flow paths 2, 3 installed therein, pipes 41, 43 extending to the outside of the furnace are connected to the flow path 2, and in the treatment method, the supply of the refrigerant to the flow path 2 is stopped, and an amorphous refractory 11 having a thermal conductivity of 20 W/(m K) or less is press-fitted into the pipes 41, 43.SELECTED DRAWING: Figure 3
【課題】流路が破損したときに、当該破損部から侵入する炉内ガスによる予期しない事象を防止するための処置を速やかかつ確実に実行する。【解決手段】内部に複数の流路２、３が形成された羽口１において、複数の流路２、３のうちの一の流路２が損傷したときにおける処置方法であって、一の流路２には、炉外に延びる配管４１、４３が接続され、処置方法では、一の流路２への冷媒の供給を停止し、配管４１、４３内に、熱伝導率が２０Ｗ／（ｍ・Ｋ）以下の不定形耐火物１１を圧入する。【選択図】 図３ |
