FIELD: chemical industry; production of titanium, silicon and phosphorus.
SUBSTANCE: proposed method includes loading the blanks into resistance batch-type furnace for graphitization of electrode blanks. Carbonic material, anthracite for example is used as charge. Carbonic material is charged into peripheral and central zones of furnace separately; peripheral zone is loaded with material subjected to preliminary heat treatment. Heat treatment of material is performed due to heat liberated by blanks in the course of passage of electric current through them during graphitization process. Rate of temperature rise does not exceed 25°C/h within range of 400-900°C. During unloading the material from furnace, carbonic material is separated by quality due to separate unloading from central and peripheral zones of furnace.
EFFECT: reduced power requirements; improved quality of material and enhanced homogeneity.
