Numerical simulation of thickness evolution of oxide scale in hot rolled strip
To reduce the incidence rate of oxide scale defects in hot rolled structural steel 510L,the numerical simulation of the thickness evolution of oxide scale during the hot rolling process was carried out.The influences of the finishing rolling inlet temperature,the finishing rolling final rolling speed,the models of interstand cooling and laminar cooling,and the product thickness on the thickness evolution of oxide scale were studied.The simulation results showed that under the hot rolling process which guaranteed qualified mechanical properties,the thickness of oxide scale could be effectively decreased by adopting the lower finishing rolling inlet temperature,increasing the finishing rolling speed,utilizing interstand cooling and selecting the front section cooling.
