微合金化加上控制冷却,是提高钢材综合机械性能的有效措施。本文作者们通过试验室试验,明确了含钛量和热轧工艺参数对低碳钛钢再结晶的影响规律,从而得出了这样的结论:含钛量为0.04～0.08%时,可以推迟该钢在轧制过程中的形变奥氏体再结晶的进行;轧制加热的适宜温度为1200～1250℃;用再结晶轧制细化奥氏体晶粒时,该钢的终轧温度应大于1000℃;ε>20～25%;空延时间应适当的加长。
Micro-alloying plus controlled cooling is an effective measure to improve the overall mechanical properties of steel. Through the laboratory tests, the authors have clarified the influence of titanium content and hot rolling process parameters on the recrystallization of low-carbon titanium steel, and concluded that when the content of titanium is 0.04-0.08%, it can be postponed During the rolling process of steel deformation austenite recrystallization carried out; rolling heating suitable temperature is 1200 ~ 1250 ℃; recrystallization rolling refined austenite grain, the steel finishing temperature should be greater than 1000 ℃; ε> 20 ~ 25%; empty delay time should be extended.
