摘要
内蒙古包钢钢联股份有限公司对美标SS310HB钢轨进行了试制,基于AREMA-2014新版美标对SS310HB钢轨的性能要求,通过添加微量合金元素,采用控制终轧温度和轧后冷却速率,使该钢淬透性提高,珠光体相变温度略为降低,进而改善了珠光体片层间距的细化和均匀化程度,提高了钢轨的强韧性,从而满足了标准要求。
The SS310HB rail of meeting the America standard need was developed in Steel Union Co. , Ltd. of Baotou Steel （Group）Corp. Based on the properties requirent of AREMA-2014 standard,and added the alloy elements and controlled the fin- ishing rolling temperature and cooling rate after rolling, the hardenability of rail was improved. The pearlite transformation tem- peraion was decreased,and the lamellar spacing of pearlie was refined. Therefore, the strength of rail was increased and met the need of standard.
