Abstract: Method for heat treating rolled stock leaving a rolling train (12), wherein the rolled stock (13) undergoes a rapid cooling treatment in a rapid cooling assembly (11) located immediately downstream of the last rolling pass, the first cooling step being followed by a temperature-equalisation step in air and at least by a second cooling treatment before being discharged and collected, the temperature-equalisation step in air and the at least second cooling treatment being set so as not to modify the surface and inner crystalline structure of the rolled stock (13) which has formed at the outlet of the first cooling treatment, the at least second cooling treatment being followed by a short segment of temperature-equalisation in air and then directly by the collection of the rolled stock (13) into compact form, such as rolls coils bundles or packs, wherein the slow cooling of the rolled stock (13) collected in compact form leads to the transformation of the crystalline structure in the stable structures.

Abstract: A method to form bundles (11) of one or more layers (20) of adjacent rolled sections (12). The method comprises discharging the rolled sections (12) from a terminal end (13a) of a transporter to cause the rolled sections (12) to fall from the terminal end (13a) onto discharge rods (14); forming at least one layer (20) of the rolled sections (12), which fall from the terminal end (13a) of the transporter (13) onto the discharge rods (14), the discharge rods (14) being arranged parallel to the transporter (13) and underneath the upper plane where the sections (12) are transported on the transporter (13). The discharge rods (14) are axially displaced with respect to the transporter (13) to define from time to time a lateral discharge space ("s") adjacent the terminal end (13a), for placing the sections (12) on the rods (14), wherein the lateral discharge space ("s") equals a transverse dimension of each rolled section (12).
