一、前言控制轧制是近年来在冶金工业中为了获得高强度和改善钢材韧性而发展起来的新工艺,它是通过控制各种冶金因素(化学成分、加热温度、形变速度、终轧温度、轧后冷却等)。将形变强化和热处理强化结合在一起,挖掘钢材性能潜力的重要手段。目前,控制轧制在基础理论和工厂实用方面的研究工作都在迅速发展着。自1979年鞍钢有计划地开展控制轧制以来,尽管只是局部控制(终轧温度,终轧压下率,轧后冷却),也已经取得了明显的经济效益。与此 I. Introduction Control rolling in recent years in the metallurgical industry in order to obtain high strength and improve the toughness of steel and the development of new technology, which is controlled by various metallurgical factors (chemical composition, heating temperature, deformation speed, finishing temperature, Cooling after rolling, etc.). The combination of deformation strengthening and heat treatment is an important means of mining the potential performance of steel. At present, the control rolling in the basic theory and practical plant research work is rapidly developing. Since the planned rollout of controlled rolling at Ansteel in 1979, significant economic benefits have been achieved despite only partial control (finish rolling temperature, finish rolling reduction, post-rolling cooling). With this
