Steel alloy manufacture. Allegheny Ludlum Steel Corporation, Brackenridge, Pennsylvania. Power for the wheels of defense industry. The power house which generates all the steam required in this plant. The heavy wires in the foreground carry current to the electric melting furnaces
Steel manufacture, Allegheny-Ludlum. White-hot steel pours like water from a thirty-five ton electric furnace. The finest quality steels and alloys are produced in these furnaces, which allow much greater control of temperature than other conversion furnaces. The proportion of electric furnace steel is rising steadily, even though this process is the most expensive
Steel alloy manufacture. Allegheny Ludlum Steel Corporation, Brackenridge, Pennsylvania. Thirty-five ton electric arc melting furnace in operation. These furnaces convert scrap iron and steel into high quality steel alloys. This type of furnace gives much faster heating and permits the accurate temperature control so necessary in the processing of the high quality steels. The alloying elements are being added to the bath of molten steel
Steel alloy manufacture. Allegheny Ludlum Steel Corporation, Brackenridge, Pennsylvania. The rapid tempo of expansion necessary to meet the ever-mounting needs of the national defense production program. In the left foreground a newly completed electric melting furnace is already in operation as a construction crew puts the finishing touches on the furnaces beyond it. In the background additional plant structure is still being built. Electric melting furnaces provide faster melting of the steel bath and more precise control of temperature which is necessary in the processing of high quality alloy steels
