在1450～1580℃范围内,对钒、硅及磷、硫等元素在碳饱和铁水与CaO-SiO_2-V_xO_y渣系间的分配进行了实验研究。结果表明:随着渣碱度B(CaO/SiO_2)的增加,钒、硅及磷、硫的分配比将增大;而提高温度将降低钒、硅在渣-铁间的分配比。应用光学碱度的概念表征熔渣的碱度,考察了在不同光学碱度及不同温度下,该渣系容钒、容磷和容硫的能力,表明光学碱度增加,渣中的钒容量,磷容量及硫容量随之增大,且它们都具有较好的线性关系。升高温度,将有利于增大渣的硫容量,但容钒、容磷能力显著降低。
In the range of 1450-1580 ℃, the distribution of vanadium, silicon, phosphorus, sulfur and other elements in the carbon saturated molten iron and CaO-SiO_2-V_xO_y slag system was studied. The results show that with the increase of slag basicity B (CaO / SiO 2), the distribution ratio of vanadium, silicon, phosphorus and sulfur will increase; while increasing the temperature will decrease the distribution ratio of vanadium and silicon in slag - iron. The concept of optical basicity was used to characterize the basicity of slag. The capability of the slag system to contain vanadium, phosphorus and sulfur at different optical basicities and different temperatures was investigated. The results showed that the optical basicity increased, the vanadium content , The phosphorus capacity and sulfur capacity increase, and they have a good linear relationship. Increasing the temperature will help to increase the sulfur capacity of the slag, but the capacity of vanadium and phosphorus will be significantly reduced.
