Steel manufacture, Allegheny-Ludlum. Here is one of the huge seventy-two inch mills used to produce smooth, bright cold-rolled finish on steel sheets. The two highly polished center rolls are reinforced by heavier rollers to assure uniform reduction in the thickness of the sheet. These mills are used in the production of high quality steel

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 manufacture, Allegheny-Ludlum. No lumberyard this! These are billets of stainless steel, ready to through the hot rolling mills to be pressed into strips. The chipping and grinding on the surfaces of these billets is designed to remove all contamination and defects, so that the steel may meet the high quality requirements of being able to resist corrosion

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. It won't be long now! Here's a pile of scrap collected from various roadside junkheaps for re-use by the steel mills producing for defense. Soon it will be loaded into open hearth and other types of furnaces to be used in the production of new steel for defense industry. Nearly forty percent of the steel produced comes from scrap metals

Steel manufacture, Allegheny-Ludlum. Engineers must be alert at all times, to see that the bearings coupling the mill engines are kept oiled. Negligence might mean long delays in steel production. The engineer above is adjusting the valve of the oil line to increase the flow (note the huge fly-wheel in the background)

Steel manufacture, Allegheny-Ludlum. Space is a prime requisite for a steel plant. The huge production machinery itself and the various tools for treatment of the steel after it has been refined may extend for acres. In the center here is the exit end of a plate mill. After the plates are hot-rolled and released, they pass through the roller leveling device at the right, where they are flattened for commercial use

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. The furnace is tiled for the pourings. The flying sparks indicate the fluidity of the steel

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
