The Electric Furnace in the Foundry. Discussion

Discussion of the paper of WILLIAM G. KRANZ, presented at the San Francisco meeting, September, 1915, and at the New York meeting, February, 1916, and printed in Bulletin No. 101, May, 1915, pp. 927 to 930. J. W. RICHARDS, So. Bethlehem, Pa.-At the present time I believe there are 35 electric steel furnaces under construction in the United States, and many more in operation. The United States Steel Corporation, for example, is putting up for one firm a plant of eight electric furnaces. The principal increase in use of the electric furnace at the present time is based on its superiority for making steel for shrapnel and for munitions of war. I understand that electric steel has been found far more reliable and suitable than ordinary steel for these purposes in Europe.
