通常对重轨表面质量要求较严。重轨钢坯一般是不进行清理的,但成品重轨尽可能进行清理则是标准的起码要求。因此,轧制工艺的效果(表面加工度和表面缺陷辗平度)对重轨表面质量就有重大的意义。在制定连铸板坯轧制重轨的工艺时,对轧制过程中表面缺陷的辗平度进行了专门的研究。在生产条件下以不同参数轧制试验钢,评价不同工艺参数对成品表面质量 Usually heavy rail surface quality requirements more stringent. Heavy rail billets are generally not cleaned, but finished heavy rail as much as possible to clean up is the standard minimum requirements. Therefore, the effect of the rolling process (surface finish and surface defect flatness) is of great importance to the surface quality of the heavy rail. In the development of continuous casting slab heavy rail rolling process, the rolling process of surface defects of the flatness of a special study. In the production conditions with different parameters of the rolling test steel, evaluation of different process parameters on the finished surface quality
