钢水质量对H型钢裂边缺陷影响的探讨与实践

CONVERTER OPERATING ON THE EDGE OF THE SLAB ROLLING CRACK AND IMPROVEMENT

铸坯轧制裂边是莱钢中型H型钢比较常见的质量缺陷。造成铸坯轧制裂边的成因较多，主要从转炉操作控制的角度分析了转炉操作对钢水质量及铸坯轧制裂边的影响，并提出了对应的改进和控制措施。

Laiwu Steel billet rolling medium-sized crack edge is the more common H beam quality defects caused by the waste volume in each of more than lOOt.Slab rolling causes more side crack, which caused due to the quality of rolled steel edge crack is more common. In this paper, the converter operation control from the perspective of the converter steel quality and operation on the edge of the slab rolling crack and made a corresponding improvement and control measures.
