| Abstract: | By using the flow field commercial software fluent,a three-dimensional finite-volume mathematical model of region electromagnetic brake process was set up in view of the flow characteristic of molten steel in the slab continuous casting mould to simulate the three-dimensional flow field.Through the numerical computation,the effect of the magnetic induction intensity,the mutual function position between magnetic field and flow field,casting speed and the side port inclination angle of nozzle on the electromagenetic brake were studied,which provided the basis for optimizing the flow field of molten steel in the mould,for designing reasonable electromagnetic brake installation and for instructing actual production. |
