Advantages of Recarburizer
Graphite recarburizer application widely, which also have to say a bit of graphite carburant, first graphite recarburizer is well absorbed ferroalloy products, carbon content in 80% of the graphite recarburizer its absorption rate is equivalent to more than 90% of the coal quality recarburizer, carburant and graphite and convenient to use does not need to be increased use of specialized equipment, the characteristics of graphite recarburizer also has the advantages of reducing energy consumption effectively, can effectively shorten the smelting time smelting effect quickly.

Type of recarburizer
Petroleum coke carburizer
Petroleum coke recarburizer, mainly produced in Liaoning, Tianjin, and Shandong, Liaoning mainly produces projectile coke. The composition is generally C: 96%-99%; S: 0.3%-0.7%. Mainly used in steelmaking, gray cast iron, brake pads, cored wire, and so on.
Graphitized recarburizer
The main materials of graphitized recarburizer are graphitized petroleum coke and graphitized electrodes. The general composition is C>98%-99.5%, S<0.05%-0.03%. Mainly used for ductile iron. It is characterized by fast absorption, high carbon, and low sulfur.
Metallurgical coke recarburizer
The so-called metallurgical coke recarburizer is the large coke usually used in cupola furnaces, and its role is not only smelting but also carbonizing the metal charge.
Calcined coal carburizer
Calcined coal carburizer ingredients are generally C: 90%-93%, S: 0.3%-0.5%. Calcined coal recarburizer is mainly used in steelmaking enterprises, and some casting enterprises use it in gray cast iron. The disadvantages are that the carbon content is low, the melting is slow, electricity is wasted, and the a large residual amount.
Recarburizer, also known as carbon additive, carbon raiser. It is a product for increasing the carbon element (C). Recarburizer is quality material as reductive agent and carbon addictive in steelmaking, with the characteristics of high recovery rate, high carbon, low sulfur, and phosphorus content, no pollution. It can effectively reduce the production cost of manufacturers. There are many types of recarburizers depending on the casting purpose, material, and method of use.
Application of Recarburizer
Carbon steel
For carbon steel production, recarburizers are used to adjust the carbon content to meet various specifications, from low-carbon steels to high-carbon steels.
Alloy steel
In alloy steel production, recarburizers are used in conjunction with other alloying elements to achieve the desired chemical composition and properties.
Production Process of Recarburizer
Electric arc furnaces (eafs)
In eafs, recarburizers are added to the molten steel to replace the carbon lost during the melting process. This helps in achieving the required carbon levels for various steel grades. Recarburizers are typically added in bulk or through controlled feeding systems to ensure precise carbon adjustments.
Basic oxygen furnaces (bofs)
In bofs, where oxygen is blown into molten iron to reduce its carbon content, recarburizers are used to reintroduce carbon after the initial reduction process. This helps in reaching the target carbon content needed for the final steel product.
