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
Carbon steel bell annealing coils are carbon steel materials processed through a specific heat treatment process known as bell annealing. Bell annealed coils exhibit a uniform microstructure and excellent mechanical properties, such as high ductility, good formability, superior surface quality, and low oxidation levels. Bell annealing also helps reduce internal stresses, preventing deformation or cracking during subsequent processing. These characteristics make the material suitable for use in precision manufacturing, high-end automotive components, specialized home appliances, and the production of other high-quality metal products.

Technology comment
Bell annealing is a traditional heat treatment process in which carbon steel coils are placed in a sealed container (i.e., a bell) and heated and cooled under controlled atmosphere and temperature. This heat treatment process aims to improve the physical and mechanical properties of the steel, such as increasing toughness, reducing hardness, and enhancing ductility. The raw material for bell-annealed coils is processed from products of a short steelmaking route.
