摘要
文章介绍了出口墨西哥380HBW级别LH在线热处理钢轨的生产工艺概况,通过对钢轨微合金化成分设计、冶炼工艺高洁净度控制和精准在线热处理工艺调控,成功批量生产LH在线热处理钢轨。钢轨各项性能满足用户技术要求和AREMA标准要求,通过SGS国际检测认证,满足国外重载铁路大轴重货运列车的运行要求,钢轨已出口至墨西哥、澳大利亚、美国等国家。
In the paper,the general situations of production processes for 380HBW grade LH on line heat treated rail exported to Mexico are introduced.Its batch production is successful by microalloying component design,control of high cleanliness for smelting process as well as accurately regulating and controlling the on line heat treatment process of rail.All its performances could satisfy the technical requirements of users and requirements of AREMA standard as well as pass the SGS international testing and certification so that it could satisfy the operating requirements of freight train with great axle load on heavy haul railway abroad.It has been exported to such countries as Mexico,Australia and America.
