Abstract
A numerical analysis has been carried out to investigate the two-phase solidification process in continuous castings. An effective heat capacity method is used for this purpose. The radiation heat transfer at the mold metal interface was taken into account. The results of this method match well with the results obtained by analytical methods. The investigation included the ranges of mold cooling rate Bi 2 , inlet temperature θ 0 , and Peclet number Pe from 0.1-0.5, 1.2-2.0, and 0.1-1.0, respectively. A constant Stefan number Ste of 2.5 was used. It is observed that the solidification process is delayed with the increase of the withdrawal speed and with the increase of the liquid metal inlet temperature. With increased withdrawal speed, the region with temperature gradient moves downward. Steep axial temperature gradient was observed in the cast metal in the mold region.
