我厂2号炉(118m~3)的汽化冷却系统由冷水江铁焦总厂设计,于1998年由包钢二冶担任施工。1990年11月5日点火投产,至1998年5月19日停炉中修,历经七年零七个半月。其间于1991年开炉四个月时停炉发现风口上拐点处基本都已侵蚀,局部冷却壁管子已外露,后补砌一次砖。1994年又进行了一次炉衬喷补,冷却壁基本完好,没有更换。原设计中的冷却壁加工单位为冷水江铁焦总厂,冷却壁的材质为耐热铸铁,内铸三排直径为φ45×5mm的无缝钢管。冷却形式为两段式汽化冷却,循环方式为自然循环和强
The gasification cooling system of No.2 furnace (118m ~ 3) in our factory was designed by Lengshuijiang Iron Coke Plant and was constructed by Baotou Second Metallurgical Plant in 1998. November 5, 1990 ignition put into operation, to May 19, 1998 shutdown furnace repair, after seven years and a half and a half months. In the meantime, when the furnace was opened for four months in 1991, it was discovered that the inflection point at the tuyere had basically eroded, and the partial stave pipe had been exposed. In 1994, a refueling of the lining was carried out. The cooling wall was basically intact and was not replaced. The original design of the cooling wall processing unit for Lengshuijiang Coke Plant, the cooling wall made of heat-resistant cast iron, cast three rows of φ45 × 5mm diameter seamless steel pipe. Cooling in the form of two-stage vaporization cooling, the cycle of natural circulation and strong
