Description
This is an all film programme, compiled from films of the British Steel Corporation. It shows some of the processes that are involved in extracting iron from iron ore, and its conversion to steel.... Scrap steel is shown as an important example of recycling basic materials. Professor Charles Neway's commentary does not deal with the technicalities in detail placing the emphasis on the scale of the operations involved. In fact this programme is "a visit to a steel works".

Footage description: Shots of an open hearth iron ore furnace. Mining of low grade iron ore discussed. Shots of open cast method of mining iron ore. Shots of higher grade iron ore being offloaded from a ship onto railway cars. Commentary explains that most iron ore used in Britain is imported. Shots of an iron ore blast furnace. C. Newey explains the ingredients and processes needed to reduce the ore to iron. Shots of ore being crushed, graded and sorted by size. Shots of coke being produced. Its role in the reduction of iron ore explained. Shots of coke and ore being fed into the furnace Shots of ovens for pre-heating air. Pre-heated air is forced into the furnace. Shot of plant for cleaning toxic gases from the blast furnace. Commentary gives the reasons for this purification. C. Newey explains the various uses for waste materials from the reduction process. Shots of ore dust being recycled and run through the blast furnace. Shot of slag being transported away to be used as fertilizers and road ballast. Shots of iron being run from the furnace and cast into pigs. Newey discusses some of the uses for pig iron. Shots of iron being run into special containers for transport to steel works. Shots of a bulk oxygen furnace being primed with steel scrap. Commentary by Newey discusses reasons for this. Shot of an oxygen lance in the furnace. Shot of furnace control room. Commentary explains the importance of the oxygen blow. Shots of steel being produced in a bulk oxygen converter. Shots of converter being tapped and ingots of steel being produced. Working of steel into proper shapes and sizes taken up. Shots of steel ingots being rolled, mangled and squeezed into a variety of shapes. Shot of the steel works control room and computer. Shot of steel going through a hot strip mill. Shot of steel being cold rolled into large drums. Shots of cars being turned to scrap in a metal scrap yard. A car is crushed and steel is extracted by the cold liquid nitrogen process. Commentary by Newey describes the process. Use of electric ore furnace for recycling steel scraps examined. Shots of top of electric arcs furnace. Steel scrap in poured in. Shots of furnace in operation. Slag is run off and temperature checked with a pyrometer. Shot of quality test being conducted using vacuum spectroscopy method. Shots of steel being poured from the furnace and alloys being thrown in by hand. Shot of steel sample under microscope. Impurities are pointed out. Shots of molten steel running into a vacuum chamber to remove impurities. Shot of a purified steel sample under the microscope. Advantages of the continuous casting method explained by Newey. Shots of steel being poured through an open - ended mold. Newey sums up.
