冷轧基料烂边缺陷分析及应用

Analysis and Application of Cold Rolled Base Defect Analysis

从化学成分、炼轧工艺、公辅能源等方面对低成本化冷轧基料烂边缺陷进行统计分析,并同高等院校合作研究,初步弄清冷轧基料出现烂边缺陷的原因,并对此采取优化轧制计划,控制加热温度,调整化学成分,设备精度化管理等一系列控制措施,最终改善效果明显,SPHC烂边缺陷得到控制。

In this paper, Statistical analysis was made on the defects of low - cost cold rolled base materials from chemical composition, rolling process, and auxiliary energy, Cooperation with institutions of higher learning, The reasons for the de- fects of the cold rolled base are preliminarily understood, To optimize the rolling plan, control the heating temperature, ad- just the chemical composition, equipment precision management and other control measures, Finally, the improvement effect was obvious, and the defect of SPHC was controlled.
