摘要
采用合理的成分设计,通过钢质纯净化、铌钛微合金化和控轧控冷工艺,济钢开发生产了铁路货车用Q450NQR1钢。实物质量检验表明,钢带组织均匀、晶粒细小,力学性能、耐大气腐蚀性能、焊接性能均达到标准要求,现已成功供货铁路货车制造厂家。
Adopting reasonable component design, purifying liquid steel, microalloying by Ni and Ti and controlling rolling and controlling cooling process, Jinan Steel developed and produced Q450NQRI steel used for railway truck. The testing results of product quality showed that the microstnleture of the steel strip is homogeneous and the crystal particle is fine： the mechanical property, resistance to atmospheric corrosion and welding performance met the needs of the Standard, successfully supplying for the manufacturer of railway truck.
