Study on online real-time temperature field calculation model for slab caster in the system of dynamic soft reduction

In the process of soft reduction during slab solidification,the on-line calculation of temperature field in the slab is very important.Combined with traditional finite difference method,a new method which can be used for on-line calculation was presented in this paper,and the effects of steel grade and casting speed on the mushy zone were investigated.Moreover,the model was applied to actual operation and good results were obtained.
