当前,由于连铸技术的成熟和完善,钢铁厂可以生产出无缺陷的铸坯,因而又产生了连铸—连轧技术。于是在国内外出现了一批连铸坯热装热送轧制和直接轧制生产线。这种连铸—连轧的生产工艺,对铸坯质量有着严格的要求。由于是连续生产,就必须在线监 At present, due to the maturity and perfection of continuous casting technology, steel mills can produce defect-free slabs and thus produce continuous casting-continuous rolling techniques. So at home and abroad there was a number of hot rolled hot rolled rod and direct rolling production line. This continuous casting - continuous rolling production process, the quality of the slab has strict requirements. Because it is continuous production, it must be online monitoring
