铁道车辆是我国冶金企业铁路运输的主要运载工具。冶金企业铁路运输的特点是:车辆在厂内进行频繁的捣装作业;货物的比重大、集重大、高温砸击;装卸作业采用翻车机、抓斗、电磁盘等大型机械设备,在这种恶劣的环境下普通车辆的技术性能和设计强度不能适应冶金企业生产的要求。随着武钢生产的不断发展和机械化装卸作业程度的 Railway vehicles is China’s metallurgical enterprises of the main carrier of rail transport. Metallurgical enterprises of rail transport is characterized by: vehicles in the factory for frequent å tamper operations; large proportion of goods, set a major, high temperature smash hit; loading and unloading operations using dumper, grab, disk and other large machinery and equipment, in this Under harsh environment, the technical performance and design strength of ordinary vehicles can not meet the requirements of metallurgical enterprises. With the continuous development of WISCO production and mechanization of loading and unloading operations
