Introduction to recarburizer

What is a recarburizer?

In the smelting process of iron and steel products, due to factors such as smelting time, heat preservation time, and long overheating time, the melting loss of carbon in the iron solution increases, resulting in a decrease in the carbon content in the iron solution, resulting in the carbon content in the iron solution not reaching the theoretical value expected by refining. Carbon-containing substances added to make up for the carbon content burned during the steel smelting process are called recarburizer.

What are the classifications of recarburizer？

1.Classification by category：

①Metallurgical coke recarburizer

②calcined coal recarburizer

③composite recarburizer

④petroleum coke recarburizer

⑤columnar graphite recarburizer

⑥semi-graphite recarburizer

⑦natural graphite recarburizer

⑧graphitized petroleum coke recarburizer

2.Classification by casting use：

①Ductile iron recarburizer

②gray iron recarburizer

③cast steel recarburizer

④special recarburizer

How to use？

1. Furnace input method：It is suitable for melting in induction furnaces, but the specific use varies according to process requirements.

2. Carburization outside the furnace：(1) Graphite powder is sprayed inside the bag. (2) Use recarburizer during ironing.

What are the characteristics of high-quality recarburizer?

1. Moderate particle size, high porosity, easy melting, and fast absorption rate.

2. The chemical composition is pure with few impurities, high national carbon content, low sulfur and nitrogen content, and very few harmful components, with a high absorption rate.

3. The graphite crystal structure of the product is good, which can improve the nucleation ability of the original iron liquid.

4. Excellent performance and stability

Choosing a suitable recarburizer not only helps to reduce smelting production costs but also improves the quality of smelted metals and castings, allowing smelting metal factories and foundries to obtain economic benefits of both financial and quality.
