摘要
随着高速铁路技术的发展,用户对钢轨钢的质量、性能和纯净度提出了更高的要求,而钢轨钢的成分控制和纯净度水平是由其冶炼技术所决定的.本文对我国钢轨钢的生产情况及重轨钢的冶炼技术做了综合论述.
With the development of high-speed railway technology, higher requirements of quality, property, and cleanness of rail steel are put forward by users. The composition control and cleanness level of rail steel are determined by the smelting technology. The production status of rail steel and smelting technology of heavy-rail steel in China are summarized.
