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%.

There are two types of sulfur additive for your choice, one is called pyrite which contain 45% sulfur, and the other is contain 30% sulfur, the pyrite generally supplied in the size 3-8mm or 5-40mm can also accept customed in the size 10-50mm, the 30% sulfur type is always in the 10-50mm, it is through purity smelted, so contain less impurities, but the content of sulfur is also less, welcome for contact Anyang Huatuo Metallurgy for more details. The gray cast iron contains 0.06%-0.1% sulfur will be beneficial to improve its cutting performance, improve the inoculation effect in the production process, improve the graphite shape, and improve the mechanics of the casting.In order to obtain high quality gray mouth castings, should keep the reasonable balance of sulfur in the molten iron, if the sulfur is not unevern, it is necessray to do sulfur increasing treatment in time.

Silicon carbide can be used as metallurgical deoxidizer and high temperature resistant materials in smelting. 2. It can also be used as abrasive materials,which can be used to make abrasive tools,such as grinding wheels, oilstones, grinding head and so on. 3.Silicon carbide is a new kind of reinforced steel-making deoxidizing agent and ideal thermal insulating agent.it is used for deoxidizing. The usage dose is 1-4kg/t can make electricity consumption to reduce 15-20kw/h and time to reduce 15-20min per furnace to raise productivity rate to 8-10%.
