介绍了梅钢热轧板厂异物压入缺陷的情况。通过对缺陷进行取样分析、工艺通道的排查,分析三种缺陷产生的原因,并针对性的制定了增加导轮装置、清洁生产和卷取前收集器装置的改进等措施,减少了异物压入缺陷发生率和冷轧孔洞发生率,提高了带钢表面质量。 Describes the foreign steel hot rolling mill plunge into the case of defects. Through the sampling and analysis of the defects, the investigation of process channels, the reasons for the three defects, the measures to increase the guide pulley device, cleaner production and pre-coiler collector device were formulated and the foreign matter pressure was reduced The incidence of defects and the incidence of cold-rolled holes to improve the surface quality of the strip.
