In order to study the influence of mold flow control device(MFCD) on mold flow field at low casting speed,a full scale water model has been set up to simulate the mold flow field of vertical slab continuous caster in Baosteel.With two types of submerged entry nozzle(SEN),the effect of equipping MFCD or not,the position and the immersion depth of MFCD on mold level fluctuation and mold field distribution has been studied.The results show that MFCD has no obvious effect on the mold flow field distribution,but decreases the mold level fluctuation with downward outlet SEN.However,with upward outlet SEN,MFCD has obvious effect on the mold flow field distribution and largely increases the mold level fluctuation at some point of free surface.To the extent of immersion depth from 50 mm to 100 mm,the influence of MFCD position is more significant than MFCD immersion depth on mold level fluctuation.The MFCD is not applicable for slab continuous casting at low casting speed.
