摘要
控制轧制与控制冷却技术是钢种开发和改善产品质量的重要轧制工艺技术。介绍了热轧板带钢超快冷技术的发展前沿,重点阐述了国内自主研发超快冷工艺装备的技术特征。在此基础上,进一步介绍以超快冷为核心的新一代TMCP工艺原理以及"轧制-冷却"相结合的"温控-形变"耦合控轧技术研发现状,通过控制轧制与超快冷有效结合,综合利用细晶强化、析出强化、相变强化等多种强化方式,可以充分挖掘钢铁材料的潜力,实现资源节约型、节能减排型的绿色钢铁产品制造过程。
Thermo-mechanical controlled processing（TMCP）is an important and effective rolling technology for development of steel product and improvement of mechanical properties,which consists of controlled hot rolling and controlled cooling.We elucidate here the advanced technology mechanism and development of the ultra-fast cooling（UFC）for plate and strip production,and emphasis on the technique characterization of the UFC equipment through domestic independent research and development.The thermo-mechanical controlled processing combined with ultrafast cooling is referred as New Generation（NG）-TMCP.The superior mechanical properties can be obtained by ＂temperature-deformation＂ coupling control technology during the rolling and cooling processing,which is a consequence of grain refinement strengthening,precipitation strengthening and phase transformation strengthening.The resultant theory and technology can achieve resource conservation,energy saving and emission reduction for green steel products in the manufacturing process.
