Recarburación de grafito

Graphite Recarburizer Manufacturer

Alta carbon content

Its carbon content generally reaches over 90%, and for some high-quality products, it can even reach over 98%. This makes it can quickly replenish carbon elements to molten steel and  improve the smelting efficiency.

Bajo impurity content

After purification treatment, the contents of harmful impurities such as sulfur, phosphorus, and nitrogen are low. Thus reducing the adverse effects on the metallic properties.

Improve the graphite morphology

This makes it easy to dissolve in molten metal and absorbing quickly, which can rapidly increase the metal’s carbon content.

Guena estabilidad química

It can maintain stable performance in high-temperature smelting environments, which is unlikely to have adverse reactions with other substances.

Uniform composition

This ensures the consistency of the carbon-increasing effect.

Convenient to use

You can adjust the addition amount according to needs, thus precisely controlling the metal’s carbon content.

Uses of graphite recarburizer

Graphite recarbonizer is widely used and there are some common application fields.

The iron casting industry:

I. Grey cast iron production

By adding it during the melting process of grey cast iron, you can adjust the carbon content to an appropriate range. The range is generally 2.5% – 4%, which can promote grafitización. And it improves the machining performance and mechanical properties of the castings, such as enhancing wear resistance and compressive strength.

II. Spheroidal graphite cast iron production

You can use it for the melting of spheroidal graphite cast iron, because it can stabilize the carbon content. When being used in combination with spheroidizing agents, it can ensure the spheroidization effect. And it can enhance the toughness and strength of the castings, which is suitable for manufacturing automotive parts, pipes, etc.

III. Forgable cast iron producción

It can help adjust the carbon content of the molten iron, creating conditions for the precipitation of graphite during the subsequent annealing process. And then ensuring the machinability of the forgable cast iron.

IV. Cast Steel Industry:

You can use it in the production of various carbon steels and alloy cast steels, which replenishes the carbon elements lost during the melting process. It controls the carbon content within the designed range, which is used for manufacturing machine bed frames, engineering machinery components, etc. And it can ensure that the hardness, strength and other properties of the steel meet the standards.

Other metallurgical fields:

Powder metallurgy

En el pulvimetalurgia process, you can add it as a carbon source. It can adjust the carbon content of the alloy and produce metal powder products with specific properties.

Iron alloy production

In some iron alloy production processes, you need to control the carbon content. So you can use the graphite recarbonizer as a precise carbon additive to ensure product quality.
