摘要： Improved method for the rolling of long products in a line comprising in sequence at least one roughing assembly (11), a possible reduction/sizing assembly (19) with three rolling passes, a fast pre-finishing block (25) and a fast finishing assembly (31), the method being suitable to roll products starting with a nominal size of section between 120 and 180 mm., the products of the range of dimensions between 20 mm. and 25 mm. being finished in a reduction/sizing assembly (19) with three rolling passes positioned upstream of the fast pre-finishing block (25), the relative changes of products being concentrated in the reduction/sizing assembly (19), the whole range of dimensions of the products between 4.0 mm. and 20 mm. being subjected to the same reduction sequence up to last rolling pass of the fast pre-finishing block (25), the changes of products being carried out only in the rolling passes of the fast finishing assembly (31), the temperature of a bar entering the fast finishing assembly (31) being about 700 to 750°C., in which method the bar upstream of the fast finishing assembly (31) is subjected to a cooling with water at a low pressure of about 6 bar such as will prevent the initiation of vibrations at the point of the bar travelling through the cooling line.
Improved rolling line for long products which comprises at least one roughing assembly (11), a fast pre-finishing block (25) and a fast finishing assembly (31), the line being suitable to roll products starting with a nominal size of section between 120 and 180 mm., two pairs of cantilever rolling blocks (13) with rolling stands having alternate horizontal/vertical axes being included between the roughing assembly (11) and the fast pre-finishing block (25) and being followed by a reduction/sizing assembly (19) with three rolling passes having the function of finishing the products in the range between 20 mm. and 25 mm., the fast finishing assembly (31) having four rolling passes and comprising two separate modules, each having two rolling passes, in which line at least the fast finishing assembly (31) and/or the reduction/sizing assembly (19) with three rolling passes are associated with an assembly (218, 118) performing the fast change of equipment according to the required reduction.

摘要： 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 rolls or coils on a winding assembly (16), wherein the slow cooling of the rolled stock (13) wound in compact form on the winding assembly (16) leads to the transformation of the crystalline structure in the stable structures.
Device for heat treating rolled stock achieving the method as described above.
