摘　　要：以汽车外板为代表的高端冷轧板材对连铸板坯的表面质量要求非常高,需要通过板坯精整来提高产品的质量。对四面火焰清理、板坯修磨和手工火焰清理共3种板坯精整工艺进行了对比分析,分析得出板坯热修磨替代手工火焰清理作为板坯局部清理,对热轧工序可节约能耗14千克标准煤/t。基于分析结果,火焰清理配套修磨作为板坯精整工艺应用于工程实践。此板坯精整工艺是钢企规模化生产高端冷轧板材的可靠与经济手段,将会得到广泛的应用。High-end Cold rolling plate as Automobile outer panel asks high surface quality of slab,and slabs conditioning is required to improve the product quality. Three kinds of slabs conditioning process as four-face scarfing,slabs grinding and handling scarfing was comparison and analyzed,pointing out that hot-slab partial grinding replacing handling scarfing would reduce energy 14 kgce/t. Base on the analysis,slabs conditioning as scaring and grinding is put into practice. This conditioning process is reliable and economic for steel plant to produce high-end cold rolling plate in scale production,and would be widely applied.
