摘　　要：针对安钢150 t转炉汽化烟道循环系统固定烟罩、尾部烟道频繁漏水问题,安钢对转炉汽化烟道循环系统进行改造。将原系统设计的1用1备高压泵改为2用1备增加循环冷却水量,并将尾部烟道高压自然循环改为强制循环并入固定烟罩强制循环系统,延长固定烟罩使用寿命6个月以上,减少尾部烟道漏水80%以上。The vaporization flue circulatory systems were reformed to solve the leakage problems of the fixed chimney cap and the tail flue of the 150 t converter in Anyang Iron ＆ Steel Group Co. , Ltd. An extra pump was added into the old high -pressure pump system to enhance the circulatory cooling water flow, and the natural circulation system of the tail flue was changed for the forced high-pressure circulation system and combined with the forced circulation system of the fixed chimney cap. This optimization measure extended the service life of the fixed chimney cap for more than six months, and decreased the water leakage of tail flue by ahnost 80%.
