Description

This dataset is a market dataset representing the consumption market of the region. The dataset includes the transportation of products from the factory gate to the consumer end, with transport services calculated according to the transportation situation of this product in the region. A carbon steel bell annealed coil is a type of carbon steel material that has been treated with a specific heat treatment process, namely bell annealing. The characteristics of this material make it suitable for precision manufacturing, high-end automotive components, special home appliances, and other high-quality metal products. This dataset is formed by aggregating data from multiple sources.

Activity Description

The production process of annealed coils includes stages such as heating, holding, and slow cooling of the cold rolled plate, covering energy consumption, material consumption, waste management, and environmental emissions required in the production process.

Process Description

Bell annealed carbon steel coil is a type of carbon steel material processed through a specific heat treatment process, namely bell annealing. Bell annealed coils feature a uniform microstructure and excellent mechanical properties, such as high ductility, good formability, superior surface quality, and lower oxidation levels. Bell annealing also helps to reduce internal stresses, preventing deformation or cracking during subsequent processing. These characteristics make the material suitable for precision manufacturing, high-end automotive components, specialized home appliance products, and other high-quality metal fabrication.

Technology comment

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