Technology comment
Bell annealing is a traditional heat treatment process in which carbon steel coils are placed in a sealed container (i.e., a hood) and heated and cooled under controlled atmosphere and temperature. This heat treatment process aims to improve the physical and mechanical properties of steel, such as enhancing toughness, reducing hardness, and increasing ductility.
