充分考虑到二次冷轧(DCR)机组生产特点,从设备与工艺两个方面入手,兼顾到带钢的表面质量与板形控制,开发出一套新型切水装置与喷淋控制工艺,形成了一套完整的轧辊喷淋冷却控制新技术,消除了原设计因使用挤干辊组进行“切水”的弊端,在保证了带钢表面质量的同时也提高了成品带钢的板形精度,并将其推广应用到宝钢DCR机组,大大降低了机组的板形与表面缺陷封闭率,取得了良好的经济效益。
Taking fully into account the secondary cold-rolled (DCR) unit production characteristics, starting from the two aspects of equipment and technology, taking into account the strip surface quality and shape control, developed a new type of water cutting device and spray control process to form A complete set of roll spray cooling control of new technologies to eliminate the original design due to the use of squeeze roll group “cut water ” drawbacks, while ensuring the quality of the strip surface but also improve the finished strip steel Shape accuracy, and its popularization and application to the Baosteel DCR unit, greatly reducing the plate form and surface defects sealing rate, and achieved good economic benefits.
