亮带隆起是热轧带钢产品中主要的质量缺陷之一。造成热轧带钢局部隆起的原因主要有轧辊的不均匀磨损和带钢的不均匀温降。本钢1700热轧生产线通过及时监测并调整板凸度,改善生产计划,以及加强对工作辊和冷却设备的维护管理等措施,有效降低了亮带缺陷出现的几率。对亮带缺陷控制的成功,也表明亮带缺陷完全是可防可控的。
Belt bulge is one of the major quality defects in hot strip products. The causes of the local uplift of the hot strip are the uneven wear of the roll and the uneven temperature drop of the strip. The Benxi Iron and Steel 1700 hot rolling production line through the timely monitoring and adjustment of plate crown, improve production planning, and to strengthen the work roll and cooling equipment maintenance and management and other measures to effectively reduce the risk of bright strip defects appear. The success of bright strip defect control also shows that bright strip defects are completely preventable and controllable.
