Technology comment

Continuous annealing is a precise heat treatment process aimed at improving the physical properties of carbon steel, primarily achieved through heating and controlled cooling. This process reduces the hardness of the steel, increases its toughness and ductility, thus making the material easier to stamp, bend, and form. The raw material for continuous annealed coils is processed from short-process steelmaking products.
