Smelting of chromium molybdenum steel was made in an arc-furnace with the bottom paved, by stamping, with electrically fused dunite. The degree of erosion of the stamped dunite was determined by the change of the composition of slag during smelting operation and also by the change of the appearence of the furnace bottom after smelting. It was found that the degree of erosion was almost the same with the case in which conventional dolomite or magnesia was used. The disadvantage in using the stamped dunite was dissolution of a trace of sulfur contaminated in the dunite into steel, which should be avoided in making non-sulfur steel. Use of electrically fused dunite of extremely low sulfur content, or purification of dunite by washing or acid-pickling was found to be effective for avoiding contamination of steel by sulfur.
