耐磨耐蚀轻轨新钢种36CuPCr、55PV 各项性能均达到或超过现有进口日本电炉钢轻轨实物水平。其σ_n、HB 比普碳轻轨分别提高5～9 kg/mm~2和27～37;比日本轻轨分别提高4～8 kg/mm~2和23～33。耐磨性和实物疲劳性能分别提高5.3～1.8倍和1.3～0.8倍。耐蚀性能接近日本轻轨。经煤矿一年多时间试铺,表现出良好的耐蚀性能,其使用寿命比普碳轻轨可提高0.5倍以上。
Wear-resistant corrosion light rail new steel 36CuPCr, 55PV various properties have reached or exceeded the existing level of imported electric furnace steel rail light rail. The σ_n and HB increased by 5 ~ 9 kg / mm ~ 2 and 27 ~ 37 respectively compared with that of light carbon rail, and increased by 4 ~ 8 kg / mm ~ 2 and 23 ~ 33 respectively than Japanese light rail. Wear resistance and physical fatigue performance increased by 5.3 to 1.8 times and 1.3 to 0.8 times. Corrosion resistance close to Japan’s light rail. After more than a year of mine trial shop, showing good corrosion resistance, its service life can be increased more than 0.5 times the Cape carbon light rail.
