The electrically calcined anthracite is used as an important raw material for producing downstream carbon-containing high-quality products, and has excellent properties such as low ash content, low specific resistance and good homogeneity. The electrically calcined anthracite is produced by adopting a carbon electric forging furnace; the electric carbon calcining furnace is a high-temp calcining equipment for carbon raw material, its heat source is that current is conducted to anthracite filled in the furnace by means of conductive electrode, and its self-resistance is heated so as to make the calcined carbon raw material attain the goal of correspondent performance index.
