摘要
当圆钢成品表面存在有刮伤、压痕、折叠等缺陷的时候,锻打时会开裂成为废品。介绍降低轧制过程中的表面质量缺陷,提高圆钢热顶锻性能合格率的措施及其效果。
Round steel would crack while heading when there were scratches,dinges and pincher on the product surface,and hence become rejected product.The countermeasures to decrease the surface quality defects occurred during rolling,improve the roundness of hot heading property of round steel and its effects were introduce.
