摘　　要：针对厚规格耐候钢板热轧时出现表面裂纹缺陷,通过研究分析其产生原因,并提出控制方法。结果表明,成分设计时提高Ni:Cu比;采用高温快烧的加热工艺,并保证加热炉呈还原性气氛;减少轧制道次,提高每道次的压缩比,通过以上措施能有效降低厚规格耐候钢板表面裂纹发生的几率。For the surface cracks formed on heavy weather resistant steel during rolling,the paper studied the formation causes and control methods. The results show that the surface cracks on the steel plate were effectively controlled,when raise the ratio of Ni and Cu,adopting high- temperature- rapid- firing and ensuring furnace reducing atmosphere,and decreasing rolling paths and increasing depressing ratio could also reduce edge cracks.
