Carbon raiser, Carbon additive, or Calcined Anthracite Coal is produced in gas-fired furnaces under temperatures of 700⁰C~1300⁰C, obtaining a depolarized and partially graphitized product.
The primary application of carbon raisers is in steel mill ladles, melting, holding and even blast furnaces as carbon raisers, carbon additives, recarburizers, carburizer, injection carbon and carbon foaming material.
The raw material is procured from Ningxia a source of high-quality anthracite, with characteristics of low ash and low sulfur with High carbon content to realize higher carbon recovery.
