为了节能,不但出现了连铸技术,装热料轧制(HCR)技术和直接热轧制(HDR)技术也得到了相应的发展。为了进一步节能,一种小型轧机的概念被提了出来。这种轧机试图生产小断面尺寸的连铸坯,也即下一代连铸机。通常,由连铸机生产的板坯,其厚度在200～300mm之间。因而需要一台粗轧机来为热带钢连轧机生产热轧坯料。下一代连铸技术就是试图取消这道粗轧工序。图1示出了一种可能实现的新工艺。a)为 In order to save energy, not only continuous casting technology, hot charging rolling (HCR) technology and direct hot rolling (HDR) technology have also been developed. In order to further save energy, a concept of a mini mill is proposed. The mill is trying to produce slabs of small cross-sectional dimensions, the next-generation caster. In general, slabs produced by caster have a thickness of between 200 and 300 mm. Thus, a roughing mill is needed to produce hot-rolled stock for the hot strip mill. The next generation of continuous casting technology is trying to cancel this rough rolling process. Figure 1 shows a possible new process. a) for
