Résumé

Anthracite used for cathode block manufacturing must be calcined prior its use to eliminate volatile matter and reduce its electrical resistivity. Anthracite calcination in vertical electric arc furnaces is widely used in the industry. It is well known that this technology leads to a radial temperature gradient in the furnace which results in non-homogeneous calcined anthracite properties. Also, operation experience has shown that production of calcination furnaces can be difficult to stabilize if process changes occur, which may lead to variable quality of the calcined material. To optimize the calcination process, an improved control strategy and a mathematical model of Elkem-type electric arc furnace were developed. Using these, it was successfully demonstrated that temperature gradient in the furnace can be reduced and that furnace productivity can be substantially increased.
