| 摘 要： | 用ＴＨＥＲＭＥＣＭＡＳＴＯＲ－Ｚ型热模拟试验机模拟热连轧生产，研究终轧温度和轧后冷却工艺对Ｃ０．０７９，Ｓｉ０．０９５，Ｍｎ０．０５７，Ｐ０．０１２，Ｓ０．０２０，Ｔｉ０．０２０，Ｔｉ０．０６４，Ｃｕ０．０６钢屈服强度的影响。发现采用轧后立即水冷工艺方案时，水冷中止温度和卷取温度仅影响钢的沉淀强化组分，而终轧温度变化及轧后延迟水冷时的水冷开始温度对晶界强化组分和沉淀强化组分都有影响。文中给出了相应的强化组分定量估计公式。

| Abstract: | An investigation was made of the influence of finish-rolling temperature and control cooling on the yield strength of HSLA(0. 064Ti)with THERMECMASTOR-Z high temperature deformation simulation machine. It was found that during accelerated cooling after finish rolling the finish-cooling temperature and coiling temperature have influence on precipitation strength. During late accelerated cooling after finish rolling the start-cooling temperature have influence on precipitation and grain refinement strength. The mathematical model to predict the strength component was showed. |
