Product Introduction

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.

It is divided into ordinary carburizer and graphite carburizer. According to different smelting processes, carbon can be added during steel making and casting to increase the strength of steel and casting.

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.
