CORE CHARGE FOR ELECTRODE GRAPHITIZATION FURNACES Russian patent published in 1996 - IPC

Abstract RU 2061303 C1

FIELD: high-temperature furnaces. SUBSTANCE: core charge is composed of graphitization furnace waste having low resistivity (4-6 m Ohm) and anthracite having high resistivity (80-125 103 m Ohm) pretreated with grade B commercial lignin sulfonate for producing commercial carbon. Ingredients of core charge are taken in the following proportion, mass percent: waste - 70-90; anthracite - 10-25. Mixture of such composition provides for intersification of electric energy supply to furnace. EFFECT: improved utilization of graphitization installed capacities, reduced cost of products. 2 cl
