Manganese-carbon spheres are primarily composed of carbon and manganese, featuring high specific surface area, good electrical conductivity, and stability. Compared to traditional carbon additives, they offer more stable carbon-enhancing efficiency and lower nitrogen and sulfur content. The carbon recovery rate can exceed 90%, and the manganese recovery rate can exceed 95%. This product is used for carbon addition during steel tapping in converters and electric arc furnaces, or during LF refining processes.
