1. Furnace input method:
Recarburizer is suitable for melting in the induction furnace, but the specific use is not the same according to the process requirements.
(1) the use of recarburizer in medium frequency electric furnace smelting, according to the ratio or carbon equivalent requirements with the material added to the lower part of the electric furnace, the recovery rate can reach more than 95%;
(2) if the lack of carbon adjustment, the first dozen net furnace slag, plus carburant, by raising the temperature of molten iron, or artificial electromagnetic stirring to dissolve carbon absorption, the recovery rate is around 90%, if the low-temperature carbonization process, the melt furnace charge only part of the molten iron liquid under the condition of low temperature, all recarburizer one-time in liquid iron,At the same time, it is pressed into the molten iron with a solid charge so as not to expose the surface of the molten iron.By this method, the carburization of liquid iron can reach more than 1.0%.
2. Carburizing outside the furnace:
(1) spray graphite powder in the bag
Using graphite powder as recarburizer, the injection volume is 40kg/t, and the carbon content of liquid iron is expected to increase from 2% to 3%.The temperature of molten iron before carburization was 1600ºC, and the average temperature after carburization was 1299ºC.Jet graphite powder carburization, generally use nitrogen as a carrier, but under industrial production conditions, with compressed air is more convenient, and the oxygen combustion in compressed air to produce CO, chemical reaction heat can compensate part of the temperature drop, and CO reducing atmosphere to improve the effect of carburization.
(2) the use of recarburizer when iron
100-300 mesh graphite powder carburizer can be put into the bag, or from the iron tank with the flow into, after the iron liquid fully stirred, as far as possible to dissolve the carbon absorption, the recovery rate of carbon is about 50%.
