Carbon Additive

Calcined Anthracite is produced when anthracite is calcined under the temperature of 1200-1400C in vertical shaft furnaces to obtained a devolatized and partially graphitized product. Calcining is controlled  to a to achieve specific characteristics.　                                                  Advantage: low ash, low sulfur content and are processed by floatation before calcining.                                             

Application: In steel mill ladles, melting, holding and even blast furnaces as recarburizer . It has also found to be used as the substitute of calcined petroleum coke in particular application because of its comparable quality and competitive price.
