Abstract
A mathematical simulation technique for physicochemical processes occurring in the manufacture of electrode products in the Acheson graphitization furnaces was considered. The effects of the physicochemical properties of the carbon heat insulation of the furnace on the structure of its thermal field and the processes of mass transfer and gas evolution initiated by this field were studied. It was shown that, with the use of the carbon heat insulation based on anthracites from the Eastern Donbass, the homogeneity of the thermal field in the products treated can be substantially increased, whereas the thermal load on the refractory lining of the furnace can be decreased. The experimental data of commercial tests of different heat insulation compositions were given. The processes of silicon carbide formation in heat insulation were analyzed, and the areas of possible use of solid carbonaceous wastes from graphitization processes were determined.
