摘要
根据新钢7号高炉炉型设计采用的砖壁合一薄壁炉衬设计特点和不足,结合新钢高炉生产实际,在各层出水包加装了旋塞阀,实现了冷却强度的灵活控制。同时,通过采取优化高炉操作,维护好合理的操作炉型和在线砂洗等措施,7号高炉冷却壁寿命明显延长。
Based on the design characteristic and the insufficiency of No. 7 blagt furnace which adopting the thin brick - wall lining, cooling intensity is flexible controlled by adding plug valve at each emerge water bag combining the reality of blast furnace production. Cooling wall service life of No. 7 blast furnace is significantly prolonged through optimizing blast furnace operation, and maintaining the reasonable operation type and online sand washing.
