1 前言西钢2号高炉(100m~3)自1991年6月开炉以来,至1997年12月末,单位炉容产铁量达5272.72t/m~3。1997年5月以来,炉缸工作状态明显趋于恶化,具体体现在炉基温度呈升高的趋势;炉缸、炉基冷却壁水温差超标;铁口下部及炉缸、炉基表面温度大幅度升高,尤其以铁口下部最为严重;铁量差大,铁口难维持。为防止炉缸、炉底烧穿等恶性事
1 Foreword Since the blast furnace of the No. 2 blast furnace (100m ~ 3) of Xi’nan Iron & Steel Co., Ltd. was started in June 1991, the capacity of iron capacity per furnace reached 5272.72t / m ~ 3 by the end of December 1997. Since May 1997, The temperature of the furnace base and the cooling wall of the furnace base exceeds the standard. The temperature of the surface of the furnace base and the lower part of the iron mouth is greatly increased, especially the temperature at the lower part of the iron mouth The most serious; large difference in iron, iron mouth is difficult to maintain. In order to prevent the hearth, burnt bottom and other vicious things
