UNITED STATES STEEL CORPORATION MODERN STEEL MAKING PROMOTIONAL FILM MD86474

This Technicolor film, produced by the U.S. Steel Corporation, opens with a panoramic view of steel mills (:28). They rely on iron ore (:48), high-grade coke baked from bituminous coal and limestone (:49). The first step in producing steel is to make iron in the blast furnace (1:38), where raw materials are loaded into skip cars (1:48-2:00). Inside the furnace, chemical reactions occur (2:31). An animation is shown (2:42-3:32) of the lime combining with impurities in the ore and coke to form slag. Periodically, this waste material is removed (3:30). The separated molten white hot iron is released into an insulted transfer car (3:46-4:12), where it is taken to a steel-making furnaces (4:18). The transfer car pours the liquid metal (4:24-4:35) into a ladle, which is taken to the open hearth furnace (4:37). To begin this process, a charging machine loads limestone, iron ore, and steel scrap into the furnace (4:45) first, followed by a pour from the ladle (5:06). In the control room, a wall of gauges is consulte
