Molten metal from blast furnaces arrives at the open hearth foundry where it is placed in a 600 ton mixing furnace, which maintains a temperature of 2100 degrees fahrenheit. The mixing furnace acts as a sort of thermos bottle, or ore storage tank. A worker is shown here preparing an open hearth furnace for charging

Steel alloy manufacture. Allegheny Ludlum Steel Corporation, Brackenridge, Pennsylvania. Open hearth steel is also made at this plant. Here a worker sits at the controls of the charging mechanism for loading materials and elements into the furnace. This open hearth furnace has a capacity of about 100 tons per heat

Back into production go these carloads of scrap metal, Allegheny Ludlum Steele 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

Production. Tin smelting. Tapping the furnace of a Southern tin smelter in which pure tin is extracted from the raw ore of South American mines. Here tin is drawn off into floats which weigh about eighteen tons when filled. The metal is then conveyed to polling kettles, where dross or skimmings are drawn off and forwarded to another furnace for re-melting

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

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

Production. Tin smelting. "Bars" of pure tin are trimmed and cleaned before removal from the molds in which they were formed in a Southern smelter. All the trimmings are returned to the "pot boilers" for remelting. The plant, finest and most modern in the world, extracts the pure metal from South American ore

Rags. Collection and processing. A portion of the sorting room in a large Eastern rag processing plant. In this room new rag remnants, consisting chiefly of cuttings received from clothing factories, are sorted. The rags are classified and separated according to the type of cloth; colored rags are graded according to the ease with which they can be bleached. The baskets in back of the women are filled with rags that have been sorted and classified. The women work in teams of two; it takes a team about two hours to sort the rags in one full bale. In another part of the plant, a room of the same size and general appearance as this is used for sorting used rags. Shapiro Company, Baltimore, Maryland

Launching of 10,000 ton ships. Soon, one a week like this! The third 10,000 ton vessel to be launched from new shipyard on the East coast slides down the ways into the water. From the present one-every-two-weeks schedule, these "Virginia Dare" type vessels will shortly be produced at double speed; 90 ships in 90 weeks is the goal of the Maritime Commission
