Cold rolled sheet
The most common process of cold laminate manufacturing is that starting from a hot-rolled coil is pickled to obtain a surface cleaning that leaves it free of oxides and inlays, then passes through a tandem train, where the thickness is reduced to the desired one. The coils are then subjected to heat treatment or annealing, which can be continuous or bell, in order to regenerate the crystalline structure that was destroyed in the rolling process and to finish, the coils are subjected to a tempering process where surface hardening and final finishing is achieved.
