摘要:

针对马钢2座7.63 m焦炉炉顶表面平整度变差、装煤孔移位问题,进行了装煤孔底座找正和炉顶表面砖翻修的技术实践,统一装煤孔标高,使炉顶表面形成坡度。对表面砖材质进行改进,并重新设计安全通道砖,翻修效果显著,可为国内超大型焦炉炉顶表面翻修提供参考。

Abstract:

Since problems are found in two blocks of 7.63 m coke oven in Masteel,i.e.the worsened flatness of oven roof and displaced charging hole,revamp is done by restructuring the charging hole frame,re-bricklaying oven roof,re-leveling the charging hole elevation and making a roof slope.Additionally,the roof material is upgraded and the bricks for emergency evacuation lane is modified.All these revamps can be used as reference for similar projects in China.
