莱钢冷轧平整机卷取系统的改造

Reformation of the Coiling System of Cold-rolled Temper Mill

针对莱钢板带厂冷轧薄板平整机组卷取系统在平整穿带过程中容易打滑而使建张失败的问题,通过采取对卷取机卷筒表面用砂轮机打磨出菱形槽、卷筒表面涂抹皮带油、改进皮带助卷器、增设活动式助卷辊、优化平整建张模式和建张加速度等参数、规范和改进穿带操作方法的措施,使一次建张的成功率由原来的20%提高到目前90%,二次建张成功率达100%。

For strip slip and failure building tension during threading of cold rolled strip in temper mill of Laiwu Iron ＆. Steel Co. , Ltd. , the coiling system was reformed. The specific measures were that grinding diamond slot in coiler head surface by abrasive machine, smearing oil on coil head surface, improving belt wrapper, adding movable forming roller, optimizing parameters of building tension, etc. Based on it, the success rate of the first building tension was increased from 20M to 90%, and the success rate of the second building tension could be reached 100K.
