| Abstract: | The influencing factors and the control method of plate cooling rate during a controlled cooling process after rolling were researched for the 4 300 mm plate mill with the advanced cooling system.The effect of heat transfer,nozzle and the flow rate of header on cooling rate was analyzed to confirm the control scope of the cooling rate for different thickness plates.The calculation model of cooling rate was established to improve the control accuracy of cooling rate by combining the self-learn method.The control results showed that the cooling rate of the steel 12MnNiVR was controlled with high accuracy. |
