The recarburizer is suitable for smelting in an induction furnace, but the specific use varies according to the process requirements. (1) The recarburizer used in the smelting of the intermediate frequency electric furnace can be added to the middle and lower parts of the electric furnace according to the proportion or carbon equivalent requirements, and the recovery rate can reach more than 95%;


(2) If the amount of carbon is insufficient to adjust the carbon content, clean the slag in the furnace first, then add the recarburizer, heat up the molten iron, electromagnetic stirring or manual stirring to dissolve and absorb the carbon, and the recovery rate can be about 90%. The low-temperature recarburization process is adopted, that is, only a part of the charge is melted. When the molten iron temperature is low, all the recarburizers are added to the molten iron at one time, and the solid charge is used to press it into the molten iron to prevent it from exposing the iron. Liquid surface. This method can increase the carbon content of molten iron by more than 1.0%.
