Hot-rolled coils are made from slabs (mainly continuous cast slabs), which are heated and made into strips by rough rolling units and finishing rolling units. The hot steel strip coming out of the last rolling mill of finishing rolling is cooled to the set temperature through laminar flow, and is rolled into steel strip coils by the coiler. The cooled steel strip coils undergo different finishing operations according to the different needs of users. Lines (smoothing, straightening, cross-cutting or slitting, inspection, weighing, packaging and marking, etc.) are processed into steel plates, flat coils and slit steel strip products. With wide strength range, easy processability and excellent welding performance, the hot-rolled products of Shangang Steel are widely used in various industries, such as marine, automobile, bridge, construction, machinery, and pressure vessels. https://shangangsteelsupply.com/hot-rolled-steel-sheet-coil/
