Included activities starts

This activity starts with the processing of cold-rolled coils

Included activities ends

The boundary of production activities ends with the completion of the annealed coil, excluding transportation to the customer.

Description

The process of "1kg bell annealed, steel" refers to bell annealing of 1kg of cold-rolled coil. "Assuming 1kg of bell annealed cold-rolled coil yields 0.94114kg of bell annealed coil". The data are aggregated from multiple sources, offering good data quality with low data quality uncertainty. This dataset should be used in conjunction with 1kg of cold-rolled coil.

Activity Description

The product's activity boundary involves raw material preparation.

Process Description

The production process of batch annealing cold-rolled coils.

Technology comment

Annealing is a process to eliminate internal stresses and work hardening in steel plates caused by cold rolling. Bell annealing, which is performed in bell-type furnaces with materials arranged in stacks, has a longer production cycle. Bell annealing has strong adaptability to output and variety, and is suitable for multi-variety and small bell production.
