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