Gas Calcined Anthracite Coal

GCA coal is produced in gas fired furnaces under temperature of 700^oC~1300^oC, obtaining a devolatized and partially graphitized product.

The primary application of GCA is in steel mill ladles, melting, holding and even blast furnaces as carbon raisers, carbon additives, recarburizers, injection carbon and carbon foaming material.

Best quality Anthracite as raw materials through high temperature calcined at over 2000 by the DC electric calciner with results in eliminating the moisture and volatile matter from Anthracite efficiently, improving the density and the electric conductivity and strengthening the mechanical strength and anti-oxidation, It has good characteristics with low ash, low resistivity, low carbon and high density. It is the best material for high quality carbon products, it is used as carbon additive in steel industry or fuel.

APPLICATIONS

Calcined Anthracite Coal/Carbon Additive may substitute massively refinery coke or the stone grinds. Meanwhile its cost is much less than the refinery coke and the stone grinds. Carbon Additive may also use as the fuelIt may substitute burnt carbon massively.

Calcined Anthracite is produced when Anthracite is calcined under the temperature of 1240 in vertical shaft furnaces.Calcined Anthracite is mainly used in electric steel ovens, water filtering, rust removal in shipbuilding and production of carbon material
