【Abstract】 Based on the structure and parameters of Baosteel No.4 mould for slab continuous casting,three-dimensional numerical simulation was carried through for liquid steel flow by using the commercial software Fluent.The immersion depth of SEN, angle of the nozzle port and casting speed were studied and their influence on the steel flow in the mould was analysed.The results show that the proper immersion depth of SEN,angle of the nozzle port and casting speed are advantageous to the rising of the inclusions and to the reducing of the liquid surface fluctuation.更多还原
