由于带钢头尾在空气中停留的时间不同,导致带钢全长进入精轧时温度不一致,如果带钢全长都按照和带钢头部相同的设定值,则终轧温度头尾温差就会很大。为了保证带钢全长温度均匀,保证带钢物理性能一致,需要对带钢全长温度进行控制。在精轧轧制过程中,对带钢进行分段采样和跟踪,通过终轧温度前馈和反馈控制两种方式来进行。温度前馈控制是由L2系统的终轧
As the strip head and tail stay in the air for different time, resulting in the full length of the strip into the finish rolling temperature inconsistency, if the strip full length and strip head in accordance with the same set point, then the finishing temperature head and tail temperature difference It will be great. In order to ensure uniform strip temperature and ensure consistent strip physical properties, the strip temperature needs to be controlled. In the process of finishing rolling, the strip is sampled and tracked in sections, and the temperature is controlled by feed-forward temperature and feedback control. Feedforward temperature control is by the end of the L2 system rolling
