Carbon Raiser
Graphite Carbon Raiser refers to the deliberate arrangement of carbon product molecules through high temperatures or other methods. This molecular arrangement widens the spacing between carbon atoms, making it more conducive to decomposition and nucleation in molten iron or steel.
Product Info
There are various raw materials for carbon raisers, each with different production processes, including wood carbon, coal carbon, coke, graphite, etc., among which there are many small types under various carbon raiser. High-quality carbon raiser generally refer to carbon raiser 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 carburizing effect and insufficient carbon content in castings. The amount of carburizing agent 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. Proper selection of the carbon raiser can reduce casting production costs.Specification

Steel Manufacturing
- Graphite carbon raisers is used to enhance carbon content in steel melts during production.
- It leads to improved hardness, strength, and overall quality of steel products.
- By injecting graphite carbon raisers, steel manufacturers achieve desired carbon levels, resulting in better performance.High purity, excellent particle morphology, and a graphitized hexagonal crystal structure make graphite carbon raisers effective for carburization. Low sulfur levels are essential to maintain steel purity and prevent unwanted reactions.
