为了获得合适的钢包渣，避免IF钢RH精炼过程中的RH粘渣，研究了以CaO为基础的不同添加剂对RH精炼钢包渣熔点和粘度的影响。熔点和粘度测试结果表明，添加实验添加剂能有效降低RH精炼钢包渣的熔点和粘度。在IF钢RH精炼过程中，由于钢包渣的熔点在1280℃左右，粘度仅为0.65Pa.S，在RH精炼过程中，通过添加添加剂将碱度控制在4~5，Al_2O_3含量控制在14%~15%，可以有效地避免粘渣。
To get suitable ladle slag which can avoid slag sticking onto the RH immersion tube during RH refining process of IF steel, the effect of composition on melting point and viscosity of RH refining ladle slag was studied by different additives which is based on CaO. The results of melting point and viscosity testing experiments indicates that, the melting point and viscosity of RH refining ladle slag would decrease effectively with the add of experimental additives. During RH refining process of IF steel, adjusting the basicity to 4~5, and the content of Al2O3 to 14%~15% by adding additives, it can avoid slag sticking onto the RH immersion tube efficiently, for the reason that the melting point of ladle slag is about 1280 °C, and the viscosity is only 0.65 Pa·s.
