Description
This is a market dataset representing the consumption market in the region. It includes transportation of the product from the factory gate to consumption, with transport services calculated according to the regional transportation conditions for the product.
Activity Description
The production process of annealed coils includes heating, heat preservation, and slow cooling of hard-rolled coils, encompassing energy consumption, material consumption, waste treatment, and environmental emissions required during the production process.
Process Description
Continuously annealed carbon steel coils, typically referring to cold-rolled carbon steel coils treated by continuous annealing processes, are a highly common material in industrial applications. These coils offer excellent surface quality and a uniform microstructure, ensuring superior mechanical properties and consistent quality. Additionally, the annealing process relieves internal stresses in the steel, reducing the risk of deformation and cracking during subsequent processing. Continuously annealed carbon steel coils are high-quality low-carbon steel materials with good ductility, toughness, and weldability, widely used in the automotive, construction, machinery manufacturing, bridge structures, shipbuilding, and various industrial sectors.

Technology comment
Continuous annealing is a precise heat treatment process designed to improve the physical properties of carbon steel, primarily achieved through heating and controlled cooling. This process reduces the hardness of the steel, increases its toughness and ductility, thereby making the material easier to stamp, bend, and form. The raw material for continuously annealed coils is processed from products of the short-process steelmaking route.
