OXIDATION RETARDED GRAPHITE OR CARBON ELECTRODE AND METHOD FOR PRODUCING THE ELECTRODE |
摘要 |
<p>A method for treating a carbon or graphite electrode comprising contacting the electrode with a phosphate-containing compound and a halide-containing compound. The treated electrode is oxidation retarded and inhibits non-conductive film formation between the electrode and a copper electrode holder, thereby inhibiting arcing between the electrode and the electrode holder when used in an electric arc furnace.</p> |
