摘要
Three-dimensional mathematical model coupling of the molten steel flow and heat transfer in the slab continuous casting mold and secondary cooling zone is established to describe molten steel flow and heat transfer phenomena in the slab continuous casting mold with EMBR.The computational model is applied to investigate the flow field and temperature field in slab mold contrast with and without a constant EMBR,which strength measured at a steel plant.The study shows that The EMBR has not changed the mold steel flow field characteristic.But it has reduced the intensity of the upper and downer recirculation in the mold,reduced the speed of the upper recirculation zone,increase the free surface temperature which is compared to the state without EMBR.
