Products Description
Carbon raiser, also known as carbon additive or recarburizer, is a material added to molten metal to increase its carbon content. When being used in steelmaking or casting, the fixed carbon of carbon raiser can reach more than 95%. It has been widely used in various industries such as metallurgy, chemical, and power.
Carbon raisers are generally divided into calcined petroleum coke (CPC), graphitized petroleum coke (GPC), calcined anthracite coal (CAC), electrically calcined anthracite, and graphite electrode scraps. They are usually used for converter smelting or high-carbon steel smelting. Besides, we also offer carbon raiser columns for your option.
Features

Key Aspects Of Carbon Raiser
1. Carbon Content: The primary purpose of adding a carbon raiser is to increase the carbon content of the molten metal. This is particularly important in steelmaking, where precise control of carbon content is crucial for achieving the desired mechanical and chemical properties in the final steel product.
2. Reducing Agents: Carbon raisers act as reducing agents in certain metallurgical processes. They react with oxides in the molten metal, such as iron oxide, and help reduce them to metallic form. This is important in processes like steelmaking where the reduction of iron ore is a key step.
3. Adjusting Alloy Composition: Besides carbon, carbon raisers may contain other elements such as sulfur, nitrogen, and ash. The composition of the carbon raiser can influence the overall composition of the alloy.
4. Control of Melting Process: The addition of carbon raiser can influence the melting process by promoting uniform heating and aiding in the dissolution of alloying elements.
Common sources of carbon raisers include calcined petroleum coke, anthracite coal, and graphite. The choice of carbon raiser depends on the specific requirements of the metallurgical process and the desired properties in the final product.
In summary, carbon raisers play a crucial role in adjusting carbon content, promoting reduction reactions, and influencing the properties of molten metal in various metallurgical processes, particularly in steelmaking.
Application
Carbon raiser is mainly used to improve the carbon content in iron and steel and enhance the hardness, strength and wear resistance of iron and steel. It is typically used in the process of steelmaking and casting.
Nonferrous metals
It is used in the steel industry and metallurgical mineral processing industry.
Advanced refractory materials
It can be used as a metallurgical deoxidizer and high-temperature resistant material to make high-temperature furnace components and supports.
Abrasives
It is mainly used to make grinding wheels, sandpaper, oilstones, grinding heads, grinding pastes, and surface grinding and polishing of single crystal silicon, polycrystalline silicon and various devices in photovoltaic products.
Functional ceramics
It can not only reduce the capacity of kiln tools, but also improve the quality of kiln products and shorten the cycle. It is an ideal indirect material for ceramic glaze baking and sintering, high-temperature non-oxide ceramics, and reaction sintering ceramics.
