摘　　要：针对通钢连轧厂板带生产线的现状和特点,经过大量统计、分析和试验,找出了导致热轧带钢冷弯开裂的影响因素。通过改进生产工艺,调整钢水的纯净度,有效控制了带钢中夹杂物的级别,带钢冷弯开裂现象明显减少,取得了较好效果。Based on the present with large quantity of statistics situation and characteristic of sheet and strip production analysis and test, the factors to cold forming is found out. With improving production process, inclusion in steel is effectively controlled, the cracks obviously cause the crack on hot-rolling adjusting purity of molten steel, reduced Tong Steel, steel strip in the levels of
