摘　　要：通过 15 0tEAF LF预熔精炼渣脱硫试验表明 ,预熔精炼渣的脱硫及抑制回磷效果优于传统精炼渣。使用预熔精炼渣的平均渣量为 4.6kg/t,平均脱硫率达到 77.5 2 % ,最高脱硫率为 86%。钢水终点硫质量分数全部小于 5 0× 10 - 6 ,最低达到 2 5× 10 - 6 。预熔精炼渣具有熔化温度低 ,成渣速度快 ,脱硫效果十分稳定等特点 。Results of the industrial experiments on Desul ph urization in the 150 t EAF-LF refining process using the premelted refining sla g show that effects of the premelted slag on Desulphurization and control of rep hosphorization are superior to that of the traditional refining slag.During the Desulphurization process with the premelted slag the average slag consumption re aches 6.4 kg/t , average Desulphurization rate, 77.5 % and the highest de sulpurization rate, 86 % .The final sulphur content in steel is less than 50 ×10 -6 and the minimum, 25×10 -6 .The premelted slag featured by low smelting temperature, rapid slag forming and very stable Desulphurization effect s can satisfy the requirements of high efficiency production of LF refining proc ess.
