Description
Steam is a byproduct of the steelmaking process. It is a key form of energy used in many industrial and commercial applications, widely utilized for heating, electricity generation, and cleaning purposes. Stainless steel hot rolled coils are stainless steel products manufactured through a hot-rolling process, with main components including iron and chromium (typically no less than 10. 5%), and other elements such as nickel, molybdenum, and vanadium, sometimes also containing trace amounts of carbon. Stainless steel hot rolled coils are widely used in industries such as construction, automobile manufacturing, medical equipment, kitchenware, and food processing. The production process of hot rolled coils includes billet preheating, roughing, intermediate rolling, and finishing rolling, covering energy consumption, material consumption, waste treatment, and environmental emissions during the production process. This dataset is formed by merging data from multiple sources.

The hot rolling process involves heating the billet, produced by electric arc furnace, to its plastic deformation temperature at high temperature, typically above 1000 degrees Celsius. Subsequently, the heated billet is continuously rolled through a series of rolling mill stands. Rough rolling adjusts the billet's width and thickness via roll gap settings, while intermediate and finishing rolling further refine the dimensions and surface quality of the coil. The entire rolling process can be subdivided into stages such as roughing, intermediate rolling, and finishing rolling, ensuring that the final coil meets the required mechanical properties and surface finish.
