foreign-trader of coal/lowsulfurrecarburizer

Of recarburizer there are many kinds of raw materials, production process is also different, woodiness carbon, carbon coal, coke, graphite, such as, among them under various classification and there are a lot of small type.High quality recarburizer generally refers to after graphitization of carburant, under the condition of high temperature, carbon atoms arranged in the microstructure of graphite, so called the graphitization.Graphitization can lower the content of impurities in the carburant, improve the carbon content of carburant, reduce sulfur content.Recarburizer used in casting, can greatly increase the dosage of scrap steel, reduce the dosage of pig iron or no iron.Electric furnace smelting way of feeding, recarburizer with scrap steel should be burden to put together, such as small doses of adding can choose to add in the hot metal surface.But want to avoid mass feeding into the molten iron, in order to prevent excessive oxidation by carbonization effect is not obvious and the carbon content of the casting is not enough.Increased carbon agent, the dosage according to the ratio of other raw materials and carbon content.Different kinds of cast iron, according to need to choose different types of recarburizer.Choose recarburizer characteristics itself pure carbon graphite material, reduce too much impurity in the iron, carburant choose appropriate which can reduce the cost of castings.
