Gas Calcined Anthracite Coal Fixed Carbon 92%-93% Ash Content (%): 7.0% Max

1. Feature:

The main raw material is Ningxia unique high-quality anthracite, with characteristic of low ash and low sulfur. GCA has two main uses, namely as the fuel and additive. When being used as the carbon additive of steel-smelting, and casting, the fixed carbon may achieve above 95%. 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.

2.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 fuel, for its calorific value may achieve above 9386K/KG. It may substitute burnt carbon massively. The burnt carbon exportation needs the quota; therefore, the carburizing agent price superiority is similarly obvious. The calcination temperature of GCA is about 1200 and its electrical conductivity is far inferior to that of ECA, but the sulfur content of anthracite is usually 0.3-0.5%. GCA is widely used in steel and foundry industry as coal recarburizer by virtue of its higher cost performance.
