| Abstract: | There are many internal factors affecting surface quality of cast slab, in which heat transfer processes of mould and secondary cooling zone are two innegligible as-pects. Analysis process of heat flow state and heat process of casting powder in mould using mathematical model at home and abroad as well as development of heat exchange coefficient model of secondary cooling zone for predicting the formation of intermediate crack are briefly introduced. |
