# "THE DRAMA OF METAL FORMING" 1959 METAL FOUNDRY & FORMING PROCESS SHELL OIL INDUSTRIAL FILM 72242

Created in 1959, "The Drama of Metal Forming" is an exceptional film that shows the forming of metal in a foundry. It was directed by Peter DeNormanville and produced by Raymond Spottiswoode. 00:00 The world outputs over 350 million tons of metal annually, almost all of which goes through a forming process. Metal forming is defined as pressing, squeezing, or rolling metal into shape, as opposed to machining it. This depends on plasticity—the ability to change shape under pressure. Forming converts brittle ingots with long columnar crystals into usable shapes with a finer, more uniform internal structure. 1:55 The most important forming process is hot rolling. A slabbing mill reduces 14-ton ingots into slabs about 8 inches thick. As the rolls bite into the steel, the crystals break down and re-form, making the metal tougher and more resistant to failure. A two-high reversing mill. 5:40 The slab, once reduced to 8 inches, is cropped by shears into correct lengths. It passes through a roughing mill and then a six-stand finishing mill, where it is reduced to under an inch thick. The strip leaves the finishing mill at 2,000 feet per minute, cooled by water jets , and wound onto a coiler. The finished hot-rolled strip has a fine, regular grain structure and is tough and ductile. It is used to make products like steel pipe for household gas and water. 7:36 The hot-rolled strip is reheated in a tunnel furnace (7:36) and bent into a tube by forming rolls (7:48).
