Numerical study of secondary cooling technology in continuous casting

The quality of wide heavy plate is depended on the secondary cooling technology, which has a serious impact on the operation of the continuous casting process. Based on the realistic roller-layout and secondary cooling water design principle, a secondary cooling technology schedule of the alloyed medium carbon steel has been designed. And combining with the heat transfer and solidification numerical model, the simulation results show that the slab surface temperature obtained by designed cooling technology is closed to the target temperature, which verifies the feasibility of the secondary cooling water distribution scheme.
