一种生产IF钢的工艺方法及装置
摘要：
本发明提供了一种生产IF钢的工艺方法及装置，所述方法包括：控制板坯加热至1050～1250℃后，对板坯进行粗轧；控制粗轧出口温度不低于880℃；控制精轧入口温度为820～900℃；控制精轧出口温度为780～880℃；控制卷取温度为560～700℃，获取热轧板；对所述热轧板进行冷轧时，控制冷轧压下率为70～90％；其中，所述IF钢的组分包括Ti；如此，采用Ti添加的IF钢，优化全流程热轧、冷轧和退火工艺参数，采用低温精轧，获取较低的性能各向异性的IF钢。
摘要（英）：

The invention provides a method and a device for producing IF steel. The method comprises the following steps: controlling a plate blank to be heated to 1050-1250 DEG C and carrying out rough rolling on the plate blank; controlling rough rolling exit temperature to be not lower than 880 DEG C; controlling finish rolling entry temperature to be 820-900 DEG C; controlling finish rolling exit temperature to be 780-880 DEG C; controlling coiling temperature to be 560-700 DEG C to obtain a hot-rolled plate; and controlling cold rolling reduction ratio to be 70-90% during cold rolling of the hot-rolled plate. Components of the IF steel comprise Ti. Through the method and the device for producing the IF steel, the IF steel with the Ti is adopted; process parameters of all processes of hot rolling, cold rolling and annealing are optimized; a low-temperature finish rolling process is used for obtaining low-performance aeolotropic steel.
