装有在线轧辊磨头的成对交叉辊(PC)热轧机改善了板带凸度、板形控制及实现了自由规程轧制。在中板轧机上采用了PC技术后也改善了产品质量、减少了轧制道次、提高了生产率、降低了板坯温降和能源消耗。使用在冷轧机上时的预期效果包括提高压下率和改善板型(边部减薄)。 Paired crossed roll (PC) hot rolling mills with on-line roll mills improve board crown, form control and free-form rolling. The use of PC technology in the plate mill also improves product quality, reduces rolling passes, increases productivity and reduces slab temperature drop and energy consumption. Expected effects when used on a cold mill include increased reduction and improved plate form (edge ​​reduction).
