通过八炉不同成分钢种的试验研究,其结果与现场高强轨、AP1轨、AP1吹氩或不吹氩轨、AP1上注或下注轨、高硅轨、高硅稀土硅、中硅稀土轨对比(包括化学成分、机械性能、冲击功、硬度的对比),用断裂韧性手段,对各种性能进行了全面的分析和论述。提出在高硅轨的基础上,加入微量元素,以期提高高强轨的强韧性,发展高强轨。 Through the eight furnaces of different components of steel, the results of the field with high-strength rail, AP1 track, AP1 argon or argon blowing track, AP1 betting or betting track, high silicon rail, high silicon rare earth silicon, rare earth silicon Track comparison (including chemical composition, mechanical properties, impact energy, hardness contrast), with the means of fracture toughness, a comprehensive analysis and discussion of various properties. Based on high silicon rail, adding trace elements is proposed to improve the strength and toughness of high strength rail and develop high strength rail.
