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 billets are rolled at high temperature into flat plates of a certain thickness. The main characteristics of this type of steel are its excellent ductility and toughness, making it easy to form and process in industrial applications. Carbon steel, also known as carbon structural steel, has a carbon content of approximately 0. 0.02%-2%. Carbon steel is divided into high-carbon steel, medium-carbon steel, and low-carbon steel. The higher the carbon content, the greater the hardness, strength, and wear resistance of the steel after heat treatment, but it also becomes more brittle. The lower the carbon content, the softer and more ductile the steel. Carbon steel hot-rolled coils are widely used in construction, machinery manufacturing, automotive, and shipbuilding industries for manufacturing various structural components and parts. Due to their cost-effectiveness and processing flexibility, they are one of the most commonly used types of steel.

Technology comment
The hot rolling process involves heating the metallurgically treated billet at high temperatures to its plastic deformation temperature, typically above 1000°C. Subsequently, the heated billet is continuously rolled through a series of rolling mill stands. In the initial rolling stage, the width and thickness of the billet are adjusted through roll gap settings, while intermediate and finishing rolling further refine the dimensions and surface quality of the strip. The entire rolling process can be subdivided into stages such as roughing, intermediate rolling, and finishing rolling to ensure the final coil possesses the required mechanical properties and surface finish.
