Product Description

Coal Carbon Additive also called Calcined anthracite Coal, Gas Calcined Anthracite Coal, Carbon Raiser,Recarburizer,etc.

In the smelting process of iron and steel products, factors such as long smelting time, holding time, and overheating time often increase the smelting loss of carbon in the molten iron, causing the carbon content in the molten iron to decrease, resulting in The carbon content in the molten iron cannot reach the theoretical value expected for refining. Carbon-containing substances added to make up for the carbon content lost during the steel smelting process are called Carbon Raiser.

Product Description

There are many kinds of raw materials for carbon raiser, and the production processes are also different, including wood carbon, coal carbon, coke, graphite, etc., among which there are many small types under various categories. High-quality carbon raiser generally refer to carburizers that have been graphitized. Under high temperature conditions, the arrangement of carbon atoms takes the microscopic form of graphite, so it is called graphitization.

Graphitization can reduce the content of impurities in the carbon raiser, increase the carbon content of the carbon raiser, and reduce the sulfur content. carbon raiser are used during casting, which can greatly increase the amount of scrap steel and reduce the amount of pig iron or eliminate the need for pig iron.

In the feeding method of electric furnace smelting, the carbon raiser should be put in together with the scrap steel and other charge. Small doses can be added on the surface of the molten iron. However, it is necessary to avoid feeding large quantities of materials into molten iron to prevent excessive oxidation, resulting in insignificant carbon raiser effect and insufficient carbon content in castings. The amount of carbon raiser added is determined according to the ratio and carbon content of other raw materials.

Different types of cast iron require different types of carbon raiser according to needs. The characteristics of the carbon raiser itself are to select pure carbon-containing graphitized substances to reduce excessive impurities in pig iron. Choosing the appropriate carbon raiser can reduce casting production costs.

Application

1.Mainly used in steelmaking in electrical stove, screening water, shipbuilding sandblast to remove rust.

2.Can reduce the cost of steelmaking effectively by replacing the traditional petroleum coke of carburant.

3.Used for steel making,can improve the Carbon content in steel-melting and Ductile iron foundry.
