为了减少转炉烟尘量、降低氧耗和节能，分别进行了热力学计算和实验室实验。通过冶金热力学计算分析可知，为不影响转炉炼钢终点出钢温度，混入水蒸气比例在5％～10％最佳。实验结果又表明，在该实验条件下，烟尘量及铁损随着混入水蒸气比例的提高而持续减少，并且混合喷吹水蒸气比例也在5％～10％最佳。与纯氧喷吹相比，混和喷吹水蒸气体积比在10％时，烟尘平均减少约22.4％，铁损平均减少约22.9％。

Thermodynamic calculation and laboratory experiments were carried out with the aim of re-ducing the amount of BOF dust, the oxygen and energy consumption.The best mixed with steam ratio is 5%~10%if the steel-making endpoint steel temperature is normal through the metallurgical ther-modynamic analysis.The experimental results indicate that, dust and iron loss reduce continuously with the increase of the proportion of steam, and the best mixed spraying water steam ratio is 5%~10%. The average amount of dust is reduced by 22.4% percent in the experiment of steam ratio at 10%. Compared with the pure oxygen converter experiment, TFe in dust is reduced by 22.9%percent.
