摘　　要：近几年,1420罩退产线冷轧钢卷在平整开卷时会有许多挫伤缺陷,严重影响钢卷成材率,造成严重经济损失。为了改善该类缺陷问题,本文介绍了该产线上常见的四种挫伤缺陷,分析故障原因和特点,对相关因素进行跟踪实验,验证该类缺陷与脱脂机组的相关性,实验结果表明,脱脂机组卷取机的卷取张力直接导致钢卷挫伤,验证了卷取模式与钢卷挫伤的关系。最后,根据跟踪实验结果对脱脂机组的卷取张力进行了优化。In recent years,there are a lot of bruise defects in the cold rolled coil of 1420 hood production line,which seriously affect the yield of coil and cause great economic losses.In order to improve this kind of defects,this paper introduces four kinds of common contusion defects on the production line,their causes and characteristics,make relevant tracking experiments,verify the correlation between this kind of defects and degreasing unit,verify the relationship between the coiling tension of the coiler of degreasing unit and steel coil contusion,and also verify the relationship between coiling mode and steel coil contusion.Finally,the coiling tension of the degreasing unit is optimized according to the tracking experimental results.
