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 huge carbon electrodes of the thirty-five ton electric melting furnaces used in converting scrap iron and steel into high quality alloy steels. A worker is adjusting the rings that guide the electrodes into the arc furnace. This is just one of the new furnaces under construction at this plant to meet the expanding need for alloy steels under the emergency created by the national defenseproduction program

Steel manufacture, Allegheny-Ludlum. Ladling it out! These workers are casting ingots from the ladle into which a thirty-five ton electric furnace has just poured its molten steel. The "hot tops" allow for shrinkage of the steel in the ingots bodies. If these should be any slag left in the molten steel, it will rise into these hot tops, since slag is lighter than the steel

Steel alloy manufacture. Allegheny Ludlum Steel Corporation, Brackenridge, Pennsylvania. Converting scrap iron and steel into high quality alloy steel. A workman adds alloying materials to the bath of molten steel in one of the thirty-five ton electric arc furnaces. These furnaces give faster heating and more accurate temperature control than do open hearth 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. America builds for its Arsenals of Democracy. Workers ramming in the bottom of a new thirty-five ton electric melting furnace which two days later was placed in operation to produce steel alloys from scrap iron and steel. This plant is being expanded at record speed to keep up with the even increasing needs of the national defense production program. Allegheny Ludlum, Brackenridge, Pennsylvania

The molten stream pouring from the thirty-five ton electric furnace is slag-waste material melted down during the process of refining. It is composed largely of limestone, which carries with it various other impurities in the metal. In the foreground is a huge ladle into which the molten steel will be poured after the slag has run off
