| Abstract: | A mathematical model coupled thermal and fluid flow of alloys solidification process is de-veloped for the twin-belt thin slab continuous casting. The model is valid for three regions, i.e. solid,liquid and mushy zones in the casting alloys. Energy and flow equations are dlsCretized into finite dif-ference fornls in fixed stasgered grid,and then be solved using iterative method. Flow and tempora-ture fields,solid/liquid interface of AISI 1020 steel are presented and discued,The effects of height of nozzle and thickness of thin slab on casting process are analyzed. |
