钢产品的生产工艺从节能的角度看已经发生了很大变化,最近又采用了热装轧制工艺(HCR)HCR工艺是一个将轧制工艺和连铸工艺联系到一起的新轧制工艺。在此工艺中,连铸板坯不用冷却至环境温度而是直接装入加热炉然后再轧制。 为了使强度和韧性之间达到最佳平衡,通过控制微合金化和热机械处理已经生产出高强度低 The production process for steel products has changed dramatically from the point of view of energy saving. Recently, the Hot Rolling Process (HCR) has been adopted. The HCR process is a new rolling process that links the rolling process to the continuous casting process. In this process, the continuous casting slab is not cooled to ambient temperature but directly into the furnace and then rolled. In order to achieve the best balance between strength and toughness, microalloyed and thermo-mechanical treatments have resulted in high strength low
