Graphite Recarburizer GPC

Graphite recarburizer means that the molecular structure of carbon products is changed by high temperature or other methods, and the molecular structure of carbon is regularly arranged. This molecular arrangement allows carbon to have a wider molecular distance, which is more conducive to decomposition and forming a nucleus in molten iron or molten steel.

In the smelting process of iron and steel products, the melting loss of carbon element in molten iron is often increased due to factors such as smelting time, heat preservation time and long overheating time, resulting in a decrease of carbon content in molten iron, resulting in the carbon content in molten iron does not reach the theoretical value expected by refining.
In order to make up the amount of carbon lost in the smelting process of iron and steel, carbon-containing substances added are called recarburizer.The carbonizing agent made from coal is called coal-based recarburizer.The use of recarburizer can not only make up the loss of carbon in the process of iron and steel smelting, ensure the specific grade of carbon content of steel requirements, but also can be used for post-furnace adjustment.In cast iron, cast steel and other industrial production engineering, the addition of carbonizing agent, can play a certain role in reducing casting cost.

Product Features

1.Graphite recarburizers are divided into recarburizers for steelmaking and recarburizers for cast iron. And some other additives will also use recarburizers, for example, brake pads use additives as friction materials.
2.Graphitized petroleum coke recarburizer (carbon raiser) presents the same molecular structure as graphite microscopically. And its content of impurities such as sulfur, nitrogen, moisture and ash are all at a very low level, so as to increase the carbon content of molten iron without increasing new impurities.

Application and After-Sales Service

1.The use of graphite recarburizer during casting can greatly increase the amount of scrap steel, reduce the amount of pig iron, or eliminate the need for pig iron.
2.Graphite recarburizer is a high purity carbon product, which can reduce impurities in pig iron and effectively reduce the production cost of castings.
