| 摘 要： | 在CaO基精炼渣中加入BaO和B2O3进行改质,对改质后的精炼渣进行熔化性能和脱硫性能的实验研究.结果表明,BaO可以降低精炼渣的熔点和粘度,有效地改善钢-渣反应的动力学条件,同时增强精炼渣的脱硫能力.当BaO含量为15%～25%时,脱硫率稳定在90%以上;而B2O3对精炼渣的脱硫率无明显影响,可取代CaF2作为助熔剂加入.

| Abstract: | A desulphurization experiment was carried out by adding BaO and B_2O_3 to an CaO-based slag. The result shows that the addition of BaO can decrease the melting point and viscosity of the refining slag,improve effectively the dynamics condition of metal-slag reaction,and increase the desulphurization ability of the refining slag. When the BaO content is between 15% and 25%,the desulphurization rate is more than 90%. But the addition of B_2O_3 has little influence on the desulphurization rate,just can be added instead of CaF_2 as a flux. |
