摘要
就BaO质量含量1.0%~3.7%、TiO2质量含量1.5%~4.0%、炉渣二元碱度(CaO/SiO2)0.95~1.15的高炉渣脱硫能力进行了研究,结果表明:在实验条件下,炉渣脱硫反应是二级反应;炉渣硫分配系数Ls随二元碱度提高而提高;渣中TiO2为3%时,Ls有一峰值。
In this paper it is investigated that the desulphurization eapability of the BF slagbearing 1.0~3.7wt%baria and 1.5~4.0 wt% titanla whose basicitv varies from 0.95 to l.15.The results show that under the research conditions the desulphurization reaction is the secondorder reaction and the desulphurlzation capability″Ls″of the slag samples increases with raising ofCaO/SiO2.to has a peak value when titania content is 3 wt%in the slag samples.
