据报道,我国铁路车辆专用钢耐候钢的生产前景十分广阔。过去,我国铁路车辆多用碳素钢制造。由于这种钢耐腐蚀性能差,车辆使用5年后返修时,绝大部分已严重锈蚀,有的只剩中梁。维修时要耗费大量的人力和物力。为此,国家把耐候钢的研制列为重点攻关项目。武钢等单位承担了这项研制工作。从1980年至今,铁路部门用武钢生产的耐候钢制造的万余辆客货车,已在全国主要铁路线上运行。最近,铁道部对使用5年的耐候钢车辆解体检查,结果表明:用耐候钢制造的车辆,其耐腐蚀性能、机械性
It is reported that China’s railway vehicles for steel weathering steel production prospects are very broad. In the past, China’s railway vehicles were mostly made of carbon steel. Due to the poor corrosion resistance of this steel, when the vehicle is reworked after 5 years of operation, the vast majority of it has been seriously corroded, and some of the remaining beams have been left behind. Maintenance costs a lot of manpower and material resources. To this end, the country made the development of weathering steel as a key research project. Wuhan Iron and Steel and other units assumed the research work. Since 1980, more than 10,000 passenger and cargo trucks manufactured by the railway department with weatherable steel produced by WISCO have been operating on major national railway lines. Recently, the Ministry of Railways disintegrated the use of five-year weathering steel vehicles, the results showed that: made of weather-resistant steel vehicles, its corrosion resistance, mechanical
