Research of Mathematical Model of Solidification and Heat Transfer of Continuous Casting Slab

A mathematical model of solidification and heat transfer of continuous casting slab is established, and verified with the measured data. The influence of casting speed, casting temperature and flowrate of secondary cooling on the continuous casting slab temperature and thickness of shell is analyzed. The results show the calculation precision of the model can meet the requirements of production. Of these factors, casting speed and flowrate of secondary cooling water have much more effect on the casting slab temperature and thickness of shell, subsequently it is very important to adjust casting speed and improve the secondary cooling in the production.
