Study and implement of secondary cooling mathematical model for bloom continuous casting

Secondary cooling system is a key factor to control the quality of C-C slab.On the basis of continuous casting production and equipment conditions as well as on the target temperature of the bloom,a mathematical model for solidification heat transfer process was established.On the basis of validation of the model the secondary cooling schedule of the bloom was optimized and very good result achieved in the actual application of the model.
