重型钢轨是铁路运输事业的重要设备之一。在铁道上部建筑建设和线路维护中,大约占投资的60％左右,由此可见其重要程度。 重轨是大型钢铁企业的重点产品之一。大型钢铁企业的轨梁轧机和大型轧机,都开设重轨生产加工线,专门生产重轨。企业从炼钢开始,投入较大的人力物力,对重轨开 展科研,从重轨钢的冶炼工艺到轧钢工艺,都进行深入的研究和生产试验,使重轨质量得以不断提高。
Heavy rail is one of the important equipment of railway transportation. In the railway construction and maintenance of the upper line, accounting for about 60% of investment, we can see its importance. Heavy rail is one of the key products of large iron and steel enterprises. Large-scale iron and steel enterprises rail rolling mill and large rolling mill, are set up heavy rail production and processing lines, specializing in the production of heavy rail. Enterprises from the beginning of steelmaking, invest greater manpower and resources, carry out heavy rail research, from heavy rail steel smelting process to the rolling process, have conducted in-depth research and production tests, so that the quality of heavy rail can be continuously improved.
