长钢7号高炉炉底钻孔实践

Holing Practice in Stove Bottom of Changgang 7# BF.

长钢炼铁厂7号高炉(300m3)第二代炉役投产后,高炉炉底、炉基温度逐步升高。严重制约了高炉的强化冶炼生产。2004年9月底,利用中修机会,采取了在炉底钻孔安装冷却水管措施后,炉底、炉基温度大幅度下降并趋于稳定。

After the second generation of stove battle go into operation Cha ng gang Steel- making Plant No.7 blast furnace(300 m3),Stove bottom of the blast f urnace,stove base temperature rise progressively.Have restricted strengthening t he production of smelting of the blast furnace seriously, Will it be the end Se ptember 2004,build chance in utilizing,take in stove bottom is cool measure of t he water pipe to install to hole,stove bottom,stove base temperature drop and te nd towards stability by a large margin.
