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. Open hearth steel is also made at this plant. Workers here shown are completing the charge to an open hearth furnace which has a capacity of about 100 tons per heat. Only small quantities of materials are charged by hand in this way. The bulk of the material is charged by the mechanism shown in pictures nos. D-995 and D-994

Steel alloy manufacture. Allegheny Ludlum Steel Corporation, Brackenridge, Pennsylvania. General view of part of the plant where scrap iron and steel are converted into many grades of steel alloys. In the foreground are carloads of finished products, while in the middle foreground can be seen piles and cars of scrap coming in to feed the huge furnaces. In the background is the power house which supplies electricity and steam to turn the wheels of this important defense industry, set in the Pennsylvania hills about thirty miles north of Pittsburgh, one of America's most important steel producing centers

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

Back into production go these carloads of scrap metal, Allegheny Ludlum Steel[e] Corp., Brackenridge, Pennsylvania The melting of alloy steels for defense work requires that steel mill scrapyards such as this be constantly filled. The overhead magnet deposits the scrap in a loader which carries it to the open-hearth furnace. About 50 per cent scrap steel is used in open-hearth production

White-hot steel pours like water from a 35-ton electric furnace, Allegheny Ludlum Steel[e] Corp., Brackenridge, Pennsylvania 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. "The furnace is tilted for the pouring." The flying sparks indicate the fluidity of the steel
