【摘要】 在分析了复吹转炉脱磷的热力学与动力学条件的基础上,利用复吹转炉吹炼前期(0~8min)低温的有利条件实现钢-渣充分脱磷、倒掉脱磷渣后进行少渣冶炼、高碳下出钢。以实现复吹转炉吹炼前期高效脱磷,吹炼前期的脱磷率达到75%~93%。更多还原

【Abstract】 The thermodynamics and kinetics of combined blown BOF dephosphorization is discussed,on the basic of which the fully dephosphorization in reaction of steel and slag,little slag smelting technology after getting rid of dephosphorizing slag,equating decarburization rate and tapping in the condition of high carbon is realized by the condition of smelting prior period (0-8min).Through above technology,the highly active dephosphorization of smelting prior period in BOF combined with blowing is completed.And dephosphorization ratio is obtained from 75 %~93 % in the prior period of smelting.更多还原
