Use of oxygen in electric arc furnace in the refining process for steel production was experimented in the United States through the years of 1930 to 1940, principally for recovery of chromium in the remelting process for low carbon high-alloyed stainless steel. The experiment having been successful and the mass production of oxygen at low cost having become possible, the range of application of the same gas to various types of electric furnace in the steel refining process was enlarged. In Japan the research of oxygen application to electric furnaces was commenced belatedly as compared with that for application to open hearth furnace following the termination of the War, but the experiment has developed into the actual stage of use for production in a number of steel works. Presently the object of oxygen application involves acceleration in the melt-down stage and bessemerizing in the steel bath. The benefits of oxygen application should be, therefore, considered from the viewpoint of material and power economy, operation efficiency and quality improvement. This article dealt with the history and present condition of oxygen application to electric furnaces for steel production on the basis of a general conception gained from home and overseas reports and experiences in the authors' actual practice.
