摘　　要：为全面了解鞍钢生产的钢轨的化学成分和力学性能的情况,对2004年7月～2005年2月鞍钢生产的钢轨的化学成分和力学性能进行了统计分析.结果表明,鞍钢生产的钢轨化学成分范围较窄,力学性能相对稳定,成分的变化对性能有一定的影响.通过调整化学成分,可进一步提高钢轨的力学性能.In order to comprehensively understand the conditions of chemical composition and mechanical properties of the steel rails produced in Angang, the ones produced from July, 2004 to Feb. , 2005 are stafisficed and analyzed. As a result, the steel rails produced in Angang have more narrow range of chemical composition, the mechanical properties of which are relatively steady and the change of the former has ,some effects on the latter. Adjusting the chemical composition of the steel rail can further improve its mechanical properties.
