Steel manufacture, Allegheny-Ludlum. Back into production go these carloads of scrap metal. 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 fifty percent of scrap steel is used in open hearth production
