Abstract:
The solidification process of the molten steel on the surface of continuous casting crystallization roller was simulated by self-developed interfacial heat transfer simulator. The influences of the crystallization roller surface coating and its composition as well as thickness on heat transfer and solidification structure of the crystallization roller were studied. The results show that with a coating on the crystallization roller surface, heat flux of the interface would decrease and solidification structure uniformity would be improved. Coating composition had no obvious effect on heat transfer. With increasing the coating thickness, the decline of heat flux aggravated, which could lead to surface defects on the solidification shells.
