Description
Stainless steel hot rolled coils are stainless steel products manufactured through a hot-rolling process, primarily composed of iron, chromium (typically no less than 10.5%), and other elements such as nickel, molybdenum, and vanadium, sometimes including small amounts of carbon. Stainless steel hot rolled coils are widely used in industries such as construction, automotive 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 associated with the production process. This dataset is compiled by integrating data from multiple sources.
Activity Description
The production process of hot-rolled coils includes stages such as billet preheating, roughing, intermediate rolling, and finishing rolling, encompassing energy consumption, material consumption, waste treatment, and environmental emissions associated with the production process.
Process Description
Hot-rolled coil is a steel product produced through the hot rolling process, in which preheated steel billets are rolled into flat plates of a certain thickness at high temperatures. The main characteristics of this steel are its excellent ductility and toughness, making it easy to form and process in industrial applications. Stainless steel hot-rolled coil is a stainless steel product manufactured by the hot rolling process, with main components including iron, chromium (typically not less than 10.5%), and other elements such as nickel, molybdenum, and vanadium, sometimes including small amounts of carbon.

Technology comment
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.
