摘要: 通过半球点法研究了B2O3对40.5%-70.0%CaO-19%-45%Al2O3-SiO2-MgO-CaF2五元渣系熔化温度和完全熔化时间的影响。实验结果表明,当渣中CaO含量为40.5%~60%,CaF2 2%-10%,(B2O3%)/ (CaF2%)为0.17~0.33时,渣系的熔化温度较不加B2O3的五元渣平均降低30℃,完全熔化时间平均降低49 s。合适的多元脱硫精炼渣系的成分为60%CaO,19%-30%Al2O3,≤10%(MgO+SiO2),2%~6%CaF2, (B2O3)/(CaF2)=0.17。

Abstract: The effect of B₂O₃ on melting temperature and complete melting time of 40.5%~70.0%CaO- 19%~   45%Al₂O₃-SiO₂-MgO- CaF₂ pentary slag series by semi- sphere point method has been studied. The test results showed that the average melting temperature of pentary slag with 40.5%~60%CaO,2%~10%CaE₂and(B₂O₃)/(CaF₂) 0. 17~0.33 was 30 ℃ less than that of pentary slag series without adding B₂O3 and the average complete melting time decreased by 49 s as compared with that without adding B₂O₃.The available multicomponent desulphurization refining slag ingredient is 60%CaO,19%~30%Al₂O₃,≤10%(MgO+SiO₂),2%~6%CaF₂and(B₂O₃)/(CaF₂)=0.17.
