| Abstract: | In order to determine optimal parameters for high desulfurization efficiency in RH process,industrial experiment of RH desulfurization was carried out in PanGang Group.The results show that good desulfurization efficiency can be achieved when the content of FeO+MnO below 10 %,slag basicity over 6 and desulfurization time more than 10 min in the process of RH desulfurization.In addition,desulfurizing agent with high basicity is not only helpful for increasing the efficiency of desulfurization but also reducing the corrosion of RH equipment for longer service life.The industrial experiment showed that the desulfurization efficiency in RH process increased by 35.7 % and the corrosion of RH equipment was obviously reduced. |
| Keywords: | RH desulfurization ladle slag basicity. |
