Electrical Calcined Anthracite is made from natural anthracite by the high-temperature oven, with low ash, low sulfur, low phosphorus, high calorific value, and characteristics of high compressive strength. In the production of an electrode, This electrically calcined anthracite is one of the main materials and is also widely used for aluminum industry to make carbon anode, cathode, and cold ramming paste, Used in the manufacture of prebaked electrodes, Soderberg and tamping pastes. It is also an excellent smelting additive due to its high purity and consistency.
We used the best quality anthracite as raw materials through high temperature calcined at over 2000 by the DC electric calcined 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 Sulphur, high carbon and high density. It is the best material for high-quality carbon products and are the main materials of carbon electrode paste making and also widely used in an Aluminum Industry
