Boundary-Condition Selection in Simulating the Secondary-Cooling Zone in the Continuous-Casting Machine

详细

Methods of specifying the boundary conditions in the secondary-cooling zone of the continuous-casting machine are compared in simulating slab solidification. Experimental data are used to assess the correctness of the models. The results of simulation are different when using the mean heat-transfer coefficient for the section of the continuous-casting machine and the local heat-transfer coefficients for the zones with and without coolant. The modeling results are compared with experimental data for the surface temperature of the continuous-cast ingot at the center of its broad face.
