Carbon Raiser
Carbon raisers are generally divided into carbon raisers for steelmaking and carbon raisers for casting. Some other additives also need carbon additives, such as for brake pad additives and being used as friction materials. Carbon raisers are external carbon sources for steelmaking and ironmaking. High quality carbon raisers are essential auxiliary additives for producing high quality steel.
Carbon raisers are generally divided into calcined petroleum coke (CPC), graphitized petroleum coke (GPC), calcined anthracite coal (CAC), electrically calcined anthracite, graphite electrode scraps, and graphite column carburizer. They are usually used for converter smelting or high-carbon steel smelting. The requirements for carbon raisers used in top-blown converter steelmaking are high fixed carbon content, low ash content, low volatile, low sulfur content, low phosphorus content, low nitrogen content and low other impurities. Besides, the carbon raisers also are required to be dry, clean, and in moderate particle size.

3.High carbon, low sulfur, with stable effect for improving the carbon content
4.Used in electric furnace steel smelting and cast-iron for improving the carbon content
5.In producing casting,increase the used quantity of Scrap steel and reduce the Scrap iron.
Based on different raw materials, carbon raisers can be categorized into calcined coal carbon raisers, graphite carbon raisers, and petroleum coke carbon raisers. Depending on production processes, they can also be divided into graphite carbon raisers and calcined coal carbon raisers. Combining production processes and raw materials, the main types include graphitized petroleum coke carbon raisers (GPC), calcined anthracite carbon raisers (CAC), and calcined petroleum coke carbon raisers (CPC).
Carbon Raisers for Different Fields
Carbon Raiser for Steel
To reduce steel production costs, carbon raisers for steel usually focus on calcined coal carbon raisers. By calcining anthracite at 1500°C, impurities are effectively reduced, resulting in high carbon content, low costs, and good carbon raising effects. Calcined coal carbon raisers are widely used in various steel production processes, enhancing strength, improving plasticity, and increasing weldability.
Carbon Raiser for Casting
Since sulfur (S), phosphorus §, and nitrogen (N) severely affect casting quality, carbon raisers for casting are often required to have low sulfur, low nitrogen, and low phosphorus characteristics. Graphitized petroleum coke carbon raisers and graphitized carbon raisers are the primary types used in casting, featuring high thermal insulation, high purity, and low harmful elements, widely applied in the production of ductile iron and gray cast iron. They effectively reduce the tendency for white iron defects and enhance the fluidity of molten iron during the casting process, preventing nozzle blockage and improving the plasticity and wear resistance of castings.
