Shape defects are found in hot rolled steel strip when unwrapping tightly wound coils. This problem is particularly acute in thin strips that were considered to be defect free while processing. Process for production of coil of hot rolled strip of Nov 23, 1982 · A process for producing a coil of a hot rolled austenitic steel strip wherein a hot bar of austenitic stainless steel is hot rolled to a strip by multiple pass rolling with a total rolling reduction and finishing temperature controlled within the hatched area of FIG. 1; and wherein the hot rolled strip is allowed to cool in air for 3 to 10 seconds, cooled with water and then coiled
Steel - Steel - Treating of steel:In principle, heat-treating already takes place when steel is hot-rolled at a particular temperature and cooled afterward at a certain rate, but there are also many heat-treating process facilities specifically designed to produce particular microstructures and properties. The simplest heat-treating process is normalizing. Steel 20 (20A; 20B) / AuremoDescription. Steel 20 is used:for the manufacture of sheet metal, 12 mm 414 category, intended for cold forming; after normalization, or without heat treatment of the hooks of cranes, couplings, bearings and other components operating at temperatures from -40 °C to +450 °C under pressure; after HTO for the manufacture of gears, worms, worm pairs and other details,
Hotrolled steel coils:Hot-rolled steel coils, using slabs (mainly continuous casting slabs) as raw materials, heated to form strip steel by rough rolling units and finishing rolling units. The hot steel strip from the last rolling mill is cooled to a set temperature by laminar flow and then rolled into a steel strip coil by the coiler. The Hot Rolling Process - California Steel Industries, Inc.and finally coiling up the lengthened steel sheet for transport to the next process. The Hot Mill rolls slabs weighing up to 30 tons between 30 and 74. Steel slab 8 to 9 inches thick and up to 36 feet long is rolled into strip as thin as 1/16 inches and up to a half-mile in length.
