| Abstract: | A new 120 t top and bottom combined blown converter with TBM bottom blowing dephosphorization technology and new 6 bore great flow rate oxygen lance is built at steelmaking plant.As compared with original 80 t converter, the speed of reaction between liquid steel and slag increases,the reaction is easily tending towards balance,the average dephosphorization rate increases by 48.9%,the average time of blowing oxygen decreases by 3.5 min,the average tap to tap time reduces by 5 min,the percentage of converter end(FeO) decreases by 2.93% and the average consumption of iron-scrap charging decreases by 1 kg/t. |
