超极限规格切边和塌卷修复处理
|
摘要
在按单生产组织模式下,为满足交货的要求,需对部分已下线的缺陷钢卷进行特别处理后再次使用。介绍了对超极限带钢和塌卷带钢进行处理时的原料要求、处理方法及修正缺陷的调整措施。通过对剪切设备及张力进行调整,并采取加大卷取张力和使用纸套筒等方法,可使带钢的宽度规格和塌卷情况得到有效控制,降低了残次品数量及废品率,在提高带钢质量的同时生产安全及效率也得到提升。
In order to meet the delivery requirements under the mode of production organization according to orders, some defective coils that have been offline need to be specially treated and reused. The raw material requirements, treatment methods and adjustment measures of ultra-limit strip and collapsed strip are introduced. By adjusting the shearing equipment and tension, and increasing coiling tension and using paper sleeve, the width specifications and collapse of strip can be effectively controlled, the number of defective products and the rate of waste products can be reduced, and the quality of strip steel can be improved as well as the safety and efficiency of production can be improved.
