摘　　要：介绍了唐钢1580生产线生产J55石油套管用钢的工艺流程、产品性能及钢卷表面出现翘皮缺陷的现象。通过对比分析,查明产生翘皮缺陷的原因主要与连铸过程的工艺控制有关,连铸拉速的波动导致板坯表面微裂纹和重皮的形成,轧制后即在钢卷对应区域产生翘皮缺陷。粗扎立辊轧制力的大小不是造成翘皮缺陷的主要原因,但对翘皮的严重程度有一定的影响。The paper introduced the technology process, product property and warp defect on the surface of J55 hot rolled oil casing steel produced by 1580 production line of Tangshan Steel. By comparative analysis, the process control of casting was the main cause of wrap defect. The fluctuation of casting speed led to the micro-crack and heavy leather on slab surface, and after rolling, responding area of the coil. The rolling force of rough rolling was not the it has certain effect on the severity of wrap defect.
