The fact that when dolomite clinker was used as bed for steel making furnace, the available compound, MgO, would volatilize itself directly or would be volatilized indirectly through slag, was confirmed by both experiments done in laboratory and workshop.(1) When measured with thermo-balance, it became clear that MgO in dolomite clinker was sublimated considerably in the temperature range from 1,500° to 1,800℃. (2) The sublimation of MgO in dolomite clinker was proved by chemical analysis. (3) Studying the chemical structure of the dust rising from the dolomite clinker at high temprature, it became clear that MgO was included in it at the ratio of 50%. (4) Upon studying the dust spouting from the basic electric furnace for industrial use by chemical analysis, it was found that its principal compound was Fe_2O_3 in its melting peirod, and MgO, in both oxidizing and reducing periods. (5) It also found that a part of the dust rising in the basic electric furnace adhered to the refractories in tte furnace and that it decreased the refractoriness of the refractories.
