Included activities starts

This activity starts with the production and import of \"black plate coil, carbon steel\" in this region

Included activities ends

The activity concludes with the delivery of \"annealed steel coils, carbon steel\" to the consumers of the product. Transportation is included; however, losses of the product during transit are negligible and therefore not accounted for.

Description

This dataset is a market dataset representing the consumption market in the region. The dataset includes the transportation of products from the factory gate to the point of consumption. Transportation services are calculated based on the transportation conditions for such products in the region. Bell annealed coils have a uniform microstructure and excellent mechanical properties, such as high ductility, good formability, better surface quality, and lower oxidation. These characteristics make them suitable for precision manufacturing, high-end automotive components, special home appliance products, and other high-quality metal product production. 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.
