Abstract
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
