Technology comment
Annealing is used to eliminate internal stress and work hardening in steel sheets caused by cold rolling. Batch annealing involves annealing cold-rolled strip steel in stacks within a bell furnace. It has a relatively long production cycle, but offers strong adaptability in terms of output and product variety, accommodating a wide range of products, making it suitable for multi-variety, small-batch production.
