摘要: 在CaO基精煉渣中加入BaO和B₂O₃進行改質，對改質后的精煉渣進行熔化性能和脫硫性能的實驗研究.結果表明，BaO可以降低精煉渣的熔點和粘度，有效地改善鋼-渣反應的動力學條件，同時增強精煉渣的脫硫能力，當BaO含量為15%～25%時，脫硫率穩定在90%以上；而B₂O₃對精煉渣的脫硫率無明顯影響，可取代CaF₂作為助熔劑加入。

Abstract: A desulphurization experiment was carried out by adding BaO and B₂O₃ 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 B₂O₃ has little influence on the desulphurization rate, just can be added instead of CaF₂ as a flux.
