目前,连铸是生产厚板坯、大方坯和小方坯的主要工艺,全球大约90%的成品钢都采用连铸工艺进行生产,而在1970年,这一比例仅为4%[1]。在过去60年里,板坯连铸机经历了无数次创新改进,涵盖连铸机的所有方面。一、板坯辊子的应用范围连铸机铸坯从结晶器流出后,必须获得足够支撑,使得铸坯固化成型,从而得到较薄且完整的表层。当前 At present, continuous casting is the main process for producing thick slabs, billets and billets. Around 90% of the world’s finished steel is produced by the continuous casting process, compared with only 4% in 1970 [1] . In the past 60 years, slab caster experiences innumerable innovations that cover all aspects of caster. First, the application range of the slab roller After the caster billet outflow from the mold, you must get enough support, making the billet curing molding, resulting in a thin and complete surface. current
