摘　　要：宽板坯轧制中厚板,特别是轧制40~60 mm厚度规格时,时常出现轧后典型横裂纹缺陷。通过分析认为钢水质量、铸机设备工况、连铸拉速和冷却条件等对铸坯横裂纹的产生影响巨大。采取相应措施后,在很大程度上减少了该缺陷的产生。Typical transverse crack was uncovered in wide slab rolling,especially in 40~60 mm thickness.The analysis shows that the quality of molten steel,the working condition of casting machine,the draw-speed of continuous casting and the cooling condition have great influence on the transverse crack of casting slab.After taking corresponding measures,the de-fects are reduced to a great extent.

关 键 词：厚规格钢板 横裂纹 钢水质量 铸机工况 冷却强度
