Abstract：Aiming at the problems of low pass rate of constant temperature and constant tension in the production process of ESteel and the existence of molten steel and the weight difference between the flow of the casting machine and the rhythm of the furnace, the dynamic model calculation of the continuous casting billet online is introduced to monitor the continuous casting process status and the quality of the casting billet in real time. This model cooperates with the precision upgrade of casting machine and rolling mill equipment, stabilizes the negative difference rate of rolled products, and reduces the tensile speed frequency for casting machines with a pulling speed ratio greater than 90%. The results show that the on-line weighing rate of continuous casting blank is controlled to be greater than 80% within ±4 kg, the output of non-ruler materials within 4 m is greatly reduced, and the rolling scale rate is increased to more than 99.4%.
