【摘要】 在顶底复吹转炉熔池侧壁上安装侧吹枪,形成顶底侧吹转炉,通过工业实验对比了顶底侧吹转炉和顶底复吹转炉炼钢的冶金效果。结果表明,顶底侧吹转炉可以降低钢铁料消耗,吨钢石灰消耗可降低将近3kg,提高了转炉的脱磷能力,降低炉渣和钢水的氧化性,平均出钢碳氧积为0.0025,钢水氧化性的降低可提高合金收得率。更多还原

【Abstract】 A side blowing tuyere was applied on the bath side wall in a top and bottom blown converter to form a top-bottom -side(TBS) blown converter.The metallurgical results of the TBS converter were compared with those of a top and bottom blown converter through industrial experiment.It is found from the results that consumption of hot metal and scrap can be reduced and lime consumption of a ton of molten steel can be decreased by about 3 kg in the TBS blown converter.It can enhance dephosphorization capability and lower oxidization of slag and liquid steel.The average[C]×[O]at tap is 0.0025 in the TBS converter,which increases the yielding rate of alloy elements.更多还原
