The hot rolling process involves heating metal slabs, which have been smelted in a converter, to their plastic deformation temperature at high temperatures, typically above 1000 degrees Celsius. Subsequently, the heated slabs are continuously rolled through a series of rolling mill rolls. Primary rolling adjusts the width and thickness of the slabs through roll gap settings, whereas intermediate and finish rolling further refine the dimensions and surface quality of the coil. The entire rolling process can be细分 should be translated as subdivided here, so the final translation is: The hot rolling process involves heating metal slabs, which have been smelted in a converter, to their plastic deformation temperature at high temperatures, typically above 1000 degrees Celsius. Subsequently, the heated slabs are continuously rolled through a series of rolling mill rolls. Primary rolling adjusts the width and thickness of the slabs through roll gap settings, whereas intermediate and finish rolling further refine the dimensions and surface quality of the coil. The entire rolling process can be subdivided into stages such as rough rolling, intermediate rolling, and finish rolling, to ensure the final coil has the required mechanical properties and surface finish.
