This film was produced by Centron Films for Inland Steel in 1981. It is an educational film showing the entire process of the production of steel, from the mining of taconite, through the various stages inside the steel mill to the final product of pure steel. The film specifically focuses on the production of a steel coil.
Centron Films logo shown (0:12-0:20). Brief and eclectic range of shots; of the Chicago skyling / cityscape, farming equipment, a film projector, and two silhouetted people on bicycles (0:21-0:31). We see interior of a steel mill. Title card overlaid (0:32-0:40). More eclectic shots; we see the bow of a cargo ship at sea, a beam being lifted in a construction site, a range of steel bars in storage. Next two men seen in a kitchen appliance showroom and a busy highway (0:41-1:07). Interior of steel mill shown, then very brief range of shots of elements of the interior (1:08-1:19). We see a close up on a range of workers in action (1:20-01:30). A mechanical arm maneuvers a coil of sheet steel into place over a storeyard of coils (1:42-2:00). A range of shots of machines at work in a taconite quarry in the Iron Ranges (2:05-2:24). We see process of crushing of the rocks, extraction of iron ore and formation of pellets (2:25-2:33). Next we see extreme long shots of limestone quarrying in an area nearby. Camera pans over to a cargo ship being loaded with limestone (2:34-2:47). Shot of cargo ship carrying this freight through the great lakes (2:50-2:55). Aerial shot of steel mill on shore of one of the great lakes. Coal seen running on a conveyer belt, and being brought in by train. Aerial shot of mill continues (2:56-3:24). Stylised split screen shot showing different stages of the steel making process (3:25-3:34). Exterior shots of a coke battery. We see extraction of unwanted elements from the red hot coal, then of steaming cooled coke, recently quenched with water (3:35-4:05). Range of brief, eclectic shots around the steel mill; scoops mechanically taken from a stockpile of iron ore, an operator supervising the work from an office, coke running down a conveyer belt (4:06-4:24). Range of long shots of a blast furnace which dominates the factory (4:25-4:49). Cross-sectional animated sequence displays smelting process occurring inside the blast furnace (4:50-5:26). Footage of workers in the cast house of furnace. A tap hole opened and molten iron runs along a trough into a railway car. Brief shot of railway cars leaving the furnace (5:26-6:01). Footage of molten iron being emptied out of a vessel, and of a crane magnet picking up scrap metal (6:02-6:19). Extreme long shot of molten iron being poured into oxygen furnace (6:20-6:42). Cross-sectional animated demonstration of interior of oxygen furnace (6:43-6:55). Workers remove a sample and run a test (6:56-7:13). We then see the furnace being tapped, and ladle of molten steel removed (7:14-7:37). The continuous casting process. Molten steel is released from the base of the ladle (7:40-7:59). Animated display of continuous casting process; the steel pouring into a mould and becoming solid (8:00-8:17). Long shot of billets emerging from the casters (8:18-8:26). Wide slab of solid steel emerges from another, and is seen being cut and lifted to the next stage of process (8:27-8:45). Red-hot slab seen, having been reheated, being rolled into the strip mill, then being cooled by water in between each roller. Final very thin sheet is seen. It is seen being coiled on a roller (8:46-9:34). We see reheated steel is seen emerging into different structural shapes (9:35-9:55). Steel coil is seen being cold rolled. Annealing chamber is placed over the coil, then is seen being fed through a bath of molten zinc, showing the hot-dip galvanising process (9:56-10:43). A coil of steel lifted over a storeyard of coils (10:44-10:55). Long shots of a major city street, then of a skycraper. Very brief credits overlaid (10:56-11:11).
The Inland Steel Company was a U.S. steel company active in 1893–1998. Its history as an independent firm thus spanned much of the 20th century. It was headquartered in Chicago at the landmark Inland Steel Building. Inland Steel was integrated and reduced iron ore to steel. Its sole mill was located in East Chicago, Indiana. The steel mill's shoreline location enabled it to take in steelmaking commodities, such as iron ore, coal, and limestone, by lake freighter. It was founded by Jewish owners and provided employment to other Jewish workers.
