摘　　要：马钢二铁总厂1号高炉第2代炉役至今已开工运转4a多,由于冷却水系采用敞开式循环水工艺,其冷却设备水管已出现结垢、腐蚀现象;为此,于2010年10月和11月分别应用化学清洗与堵漏技术,安排对1号高炉所有冷却壁和发现内漏的热风炉4号热风阀进行了在线化学清洗与堵漏,完全达成预期的目的和效果,有效延长了冷却设备使用寿命。The second generation of the BF No.1 of Masteel in the ironmaking work No.2 has been operating for more than four years.Because of wide-open style circulation,there already existed scaling and corrosion inside the cooling equipment conduits.Therefore,in October and November 2010,the chemical cleaning and plugging technology were applied in online on BF No.1 cooling stave and hot air valve No.4 of hot air stove in which the leakage has been found.The expected goal and effect have been completely achieved and the service life of the cooling equipment has been prolonged effectively.
