新一代控制轧制和控制冷却技术与创新的热轧过程

New Generation TMCP and Innovative Hot Rolling Process

针对传统控制轧制和控制冷却(TMCP)技术存在的问题,提出了以超快冷为核心的新一代的TMCP技术,并详述了作为实现新一代TMCP技术核心手段的超快冷技术的科学内涵和工业装备开发情况.指出新一代TMCP技术综合采用细晶强化、析出强化、相变强化等多种强化机制,可以充分挖掘钢铁材料的潜力,节省资源和能源,优化现有的轧制过程,有利于钢铁工业的可持续发展.最后给出了以新一代TMCP为特征的创新轧制过程的案例,展示了该技术的广阔的应用前景.

A new-generation TMCP（thermo-mechanical control process） with ultra fast cooling as core technique was suggested instead of the conventional TMCP in which some problems are to be solved. Describes the ultra fast cooling technique theoretically and relevant equipment developed for commercial applications in detail. With the grain refining, precipitation and phase transformation strengthening, the new-generation TMCP was verified available to make full use the potential of steels, save resources and energy and optimize existing rolling process, thus providing beneficially a sustainable development for iron and steel industry. Some examples are given to show the characteristics of the new-generation TMCP in the rolling processes of different products especially its broad prospects in application.
