FIELD: metallurgy; electrical calcination furnaces.
SUBSTANCE: proposed furnace has cylindrical shaft whose lining is provided with circular projection, upper and lower electrodes and loading and unloading units. Circular projection secured on lining in upper half of furnace shaft is made in form of restrictor consisting of several sections of circle segments forming solid hole; surface of each section of restrictor directed towards upper electrode has rectangular part and surface of section of restrictor directed to lower electrode is horizontal. Restrictor is provided with passages for flow of gases.
EFFECT: reduced power requirements; improved quality of carbon graphite material.
