Analysis of Heat Transfer Process in the Mold for Soft-contact Electromagnetic Continuous Billet |
|
| Abstract: | The development and problems of soft-contact electromagnetic continuous casting technology were briefly introduced. According to the design parameters of the mold for soft-contact electromagnetic casting of billet in industrial processes, a mathematical model was established to describe the heat transfer of the solidification process. The velocity of the cooling water in the cylinder, the billet thickness and the wall temperature of billet were computed. Then the total quantity of heat and the heat flux through the mold in one second were also calculated. The temperatures on the surface of mold were calculated and validated according to the heat flux, which made the basic constructions of the mold for soft-contact electromagnetic casting of billet selected according to industrial processes. |
