Recarburizer to complement the carbon content in liquid steel and increase carbon material, and using anthracite as raw material calcined recarburizer inherited its three low (low ash, low sulfur, low phosphorus), six high (high calorific value, high ratio resistance, lump coal rate, Gao Huaxue activity, high plant recovery rate and high mechanical strength), the characteristics of increase the content of fixed carbon in the sintering process, reduce volatile and some redundant impurities, is the present domestic high quality refractory casting industry.
Recarburizer used in casting, can greatly increase the dosage of scrap steel, reduce the dosage of pig iron or no iron.At present most carburant are suitable for electric furnace smelting, there are also a few particularly fast absorption rate of recarburizer for cupola.Electric furnace smelting way of feeding, carburant with scrap steel such as burden should be put down inside, small doses of adding can choose to add in the hot metal surface, but want to avoid mass
Recarburizer used
In the smelting process, due to the ingredients or improper loading and decarbonization excess and other reasons, sometimes resulting in steel carbon content did not reach the top of the requirements, then to the carburization of molten steel. Recarburizer used a carbon electrode, iron powder, petroleum coke powder, charcoal powder and coke powder. Smelting, high carbon steel, containing less impurities in oil Jiaozuo carburetant. The top blown converter steelmaking carburant is high fixed carbon, ash, volatile matter, sulfur, phosphorus and nitrogen impurity content is low, and dry, clean, moderate granularity.
1 furnace input method:
Recarburizer used in induction furnace for melting, but the specific use according to the technological requirements are not the same.
(1) used in the intermediate frequency electric furnace smelting carburant, according to the ratio of and carbon equivalent requirements with the mixture into furnace in the middle and lower part and recovery rate can reach more than 95%;
(2) if the lack of adjustment of carbon carbon content when it first hit the net furnace slag, plus carburant, by raising the temperature of molten iron, electromagnetic stirring or artificial stir to dissolve carbon absorption, recycling rate in about 90%, if the use of low-temperature carbonization process, the melt furnace charge only a part of, the molten iron temperature lower, all recarburizer one-time addition of iron liquid, also with solid charge will pressing it into the liquid iron does not let its exposed out of the surface of the molten iron. The method of iron liquid carbon can reach more than 1%.
2 external carbon furnace:
(1) package of graphite powder spraying
Choose recarburizer graphite powder, blow into the amount of 40kg/t, is expected to make iron carbon content increases from 2% to 3%. With the carbon content in liquid iron is increased, decreased utilization of carbon, carbon before the molten iron temperature is 1600 degrees centigrade, the average is 1299 DEG C after carburizing. Graphite powder spray carbonization, generally uses nitrogen as a carrier, but under the condition of industrial production, it is more convenient to use compressed air, and the compression of oxygen in the air generated by the combustion of CO
(2) when the iron using recarburizer
Can be 100 - 300 to graphite powder carburizing agent into the bag, or from the iron tank with flow into, the end of the liquid iron after fully mixing, as far as possible to dissolve carbon absorption, carbon recovery rate in about 50%.

We can supply Recarburizer/ Carbon Raiser/carburetant
Recarburizer/ Carbon Raiser/carburetant are used in casting, cast iron, cast steel, and castings. There is a requirement for carbon. Therefore, as a name suggests, carbonizers are used to increase the carbon content in molten iron. For example, the common charge in smelting is pig iron, scrap, Back to the charge, the carbon content of the pig iron is high, so increasing the amount of scrap steel, reducing the amount of pig iron, and adding carbonizer can play a role in reducing the cost of castings.

1), For 1-5 T furnace:
- while a small amount molten iron in the furnace,
- or with some molten iron remained, add the carbon additive one-time,
- then add the other material.
which can make carbon additive fully absorbed.
2), For greater than 5 T furnace:
- mix proper carbon additive with charging material as suggested first,
- and then along with the increase of charging material gradually,
- that is, before the molten metal rising up to about 2/3 height of furnace,
- all carbon additive shall be added.
It guarantees sufficient melting & absorbing time before molten metal out, and improves the absorption of carbon.
