莱钢1500mm冷轧生产线平整机涂油分卷改造

Reformation of Leveling Process of 1500mm Cold Rolling Line of Laigang

针对山东钢铁莱钢集团公司1500mm冷轧线平整与拉矫产能不匹配的问题,进行了平整机后加装静电涂油机改造、卷取机橡胶套筒改造、最佳轧制力穿带控制改进,实现了板形较好的退火卷直接在平整机上进行涂油分卷而不通过拉矫机组的简约化生产模式,使莱钢冷轧退火卷的产能由原20万t/a提高到40万t/a,综合成材率提高了0.65%。

In view of the problem of capacity mismatch of leveling and withdrawal straightening of 1500mm cold rolling line of Laigang, the reformation of adding electrostatic oiler after leveling machine was carried out. Meanwhile, rubber sleeve of coiler and force control were improved. The simple production mode was realized, that good shape strip after annealing could be directly oiled and paired and not using withdrawal straightening machine. Therefore, the capacity of cold-rolled coil annealing was added from 200000 t/a to 400000 t/a, the finishing product rate was increased by 0.65%.
