Recarburizer
The recarburizer is rich in carbon elements and is widely used in steelmaking and casting. The raw materials used to produce recarburizers are mainly charcoal, petroleum coke, graphite, etc., which are smelted by electric furnace to make different types of recarburizer products. In addition to carbon, there are some sulfur, ash, volatile matter, moisture, nitrogen elements in the recarburizer, of which the casting of nitrogen and sulfur elements in the recarburizer requirements are high, through the calcination process of recarburizer can effectively reduce the sulfur elements, and the use of graphitization treatment of recarburizer can reduce the nitrogen and sulfur elements to a minimum.
What is recarburizer ?
The raw materials of recarburizer are mainly anthracite coal, petroleum coke, graphite, etc. Different types of recarburizer products are produced through calcination and graphitization process. The recarburizer has abundant carbon elements, and the rest are trace elements such as sulfur, nitrogen, ash and moisture. High-quality recarburizer particles are uniform, black and shiny. Through calcination 1500°C high temperature treatment through the recarburizer can remove most of the sulfur and nitrogen elements, so that the carbon in the recarburizer more pure.
Recarburizer specification
1.1 Graphite Recarburizer
The appearance of graphite recarburizer is columnar, black and lustrous, using the graphitization process to produce recarburizer can effectively remove sulfur, nitrogen and other harmful elements. The common graphite carbon additive particle size is 4.0mm and 3.3mm, which has the advantages of less impurities and F.C content.More

| Graphite Recarburizer | 90%/95% | 0.05%max | 800 ppm | φ 6mm, cylindrical granules |
1.2 Calcined Anthracite Coal Recarburizer
Calcined anthracite coal recarburizer has good economic efficiency and is used in steelmaking and foundry fields. It can effectively treat molten steel or molten iron. Selected high-quality anthracite coal as raw materials, smelted and smelted at a high temperature of about 1300℃, and removed the excess volatiles. It has advantages of no smoke, no peculiar smell, stable carbon increase, high recovery rate, high melting point, low burning rate and low cost etc.More

Recarburizer Application
1.1 Recarburizer Application For Steelmaking
Oxygen charging is required in the early stages of steelmaking to quickly raise the furnace temperature and provide a high temperature smelting environment. The high temperature will cause the loss of carbon in the molten steel, which will seriously affect the quality of steel if the carbon is not replenished in the molten steel in time. The use of recarburizer in steelmaking can be more easily and accurately adjust the carbon in the molten steel, while improving the fluidity of the molten steel, so that the temperature of the molten steel remains at a high temperature effect, and promote the chemical reaction between the elements in the molten steel. recarburizer is rich in carbon, compared to pig iron, scrap steel is not only cheap, and adjust the carbon in the molten steel is very good, so recarburizer in the process of steelmaking is very widely used.
1.2 Recarburizer Application For Casting
Recarburizer is widely used in casting, it can promote the number of eutectic pellets in the molten iron, promote the fluidity of the molten iron, avoid excessive oxidation of the molten iron and blockage of the outlet. In the production of ductile iron, recarburizers can effectively improve the distribution of graphite and promote the generation of graphite cores. Graphite recarburizer has low sulfur and low nitrogen characteristics, thus significantly reducing the tendency of white mouth and honeycomb holes in castings. The use of recarburizers in casting can significantly reduce the use of scrap and pig iron, thereby reducing production costs, and it can generate a large amount of heat in the molten iron, so that the iron to play a full chemical reaction.
