top blowing rate and bottom blowing rate on bath mixing time
penetrating deptht impact area and splashing amount has been studied by orthogonal design test using 1: 6.35 water model for a 50 t top and bottom combined blown converter at Tang steel. Results show that as compared to original 4-hole oxygen lance
with using improved variable angle 4-hole oxygen lance the impact area in bath increases
the penetrating depth and splashing amount decrease while the mixing time decreases. For the 50 t top and bottom combined blown converter the real lance lever ≤1.3 m is available to decrease tap to tap time and increase intensity of bath stirring; and the mixing time and splashing amount decrease by controlling top blown rate 13 000 ~ 14 000 m
