Reseach on Secondary Cooling Dynamic Control Model in Continuous Casting of Slabs

Abstract:

one improved finite volume method is proposed, expatiating on the basic idea and integrating the partial derivative equation for the secondary spary water dynamic cooling control model. The semi-discrete equation for derivative of time is obtained.Combinating with an introducted slab continuous casting production line in some steel mill, according to the Q235 actual parameters, what is obtained is surface temperature distribution, the changing of surface temperature and the water flow rate because of the varying of casting speed. The results of simulations performed using the mathematical model are validated against the measured values and a good agreement is observed, Verifing the validity of the model.The model occupies less computer memory, solving simple
