Recarburizer

Features
Calcined Anthracite (GCA)    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 achieve specific characteristics.        
Raw materials for Calcined Anthracite are selected carefully from TaiXi Anthracite Coal which is well-known for its low ash, low sulfur content     in Ningxia Province and are processed by floatation before calcining        
 
Electrically Calcined Anthracite (ECA     )is produced when Anthracite is Electrically Calcined under the high temperature of 1700-2200C in vertical shaft furnaces to obtained a devolatized and partially graphitized product. Calcining is controlled to achieve specific resistivity characteristics, generally in the range of 550-750 ohm mm2/m          
 

Application 
GCA:    The primary application of Calcined Anthracite is 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.                
 
ECA     is used as an ingredient in the production of cathode blocks for Aluminum Industry, and applied as tap-hole filling in special ferroalloy furnaces. It is also used as recarburizer in the production of steel-making because of its comparable quality and competitive price. In recent years, the consumption of ECA in the field of steel-making goes up rapidly.
