近年比利时冶金研究中心开发了被称作“铁素体轧制”的新方法,自1990年以来,比利时已在带钢热轧机上使用这种工艺生产了100多万优质商用带钢.实际年产量约60万吨.传统热轧带钢和铁素体轧制不同之处于在于:传统热轧带钢无论是粗轧还是精轧都是在奥氏体相位上进行,在最后一个精轧机后才转为铁素体;而铁素体轧制粗轧后就从奥氏体转为铁素体相位,因此精轧全是在铁素体区进行的.铁素体轧制的热轧带钢是很软的,其主要性能如下:铁素体轧制带钢与2mm厚超低碳钢我性能比较超低碳钢 铁素体轧制带钢
In recent years, the Belgian Metallurgical Research Center has developed a new method called “ferritic rolling” that has produced more than a million high-quality commercial strip on the hot strip mill in Belgium since 1990. The actual year The output of about 600000 tons.Traditional hot-rolled steel and ferrite rolling difference is that: the traditional hot-rolled steel whether rough rolling or finishing are carried out in the austenite phase, after the last finishing mill Only to ferrite; and ferritic rolling after rolling from austenite to ferrite phase, so all the fine rolling in the ferritic region of the ferritic hot rolled strip Steel is very soft, its main properties are as follows: Ferritic strip and 2mm thick ultra-low carbon steel performance comparison of ultra-low carbon steel ferritic rolled strip
