Rolling line and relative method

A rolling line for the production of flat products comprising a casting machine suitable to continuously cast a thin slab, a temperature maintenance and homogenization unit, a rolling unit comprising at least a double rolling stand of the Steckel reversing type downstream of the temperature maintenance and homogenization unit, comprising at least a forming stand or roughing stand, directly connected immediately to the exit of the casting machine and upstream of the temperature maintenance and homogenization unit, and suitable to reduce the thickness of the thin slab just solidified, the forming stand or roughing stand being configured to perform an adaptive reduction of the thickness of the thin slab smaller than or equal to about 65% at least as a function of the thickness, width and type of material of the finished flat product, and wherein the rolling unit is configured to perform a reduction of the thickness of the rolled product coming from said forming stand or roughing stand by means of at most three double rolling passes through the double rolling stand to produce a flat product having a final thickness between about 1.2 mm and about 20 mm.

A rolling method for the production of flat products comprising a continuous casting step of a thin slab, a temperature maintenance and homogenization step, a rolling step of the reversing type subsequent to the temperature maintenance and homogenization step, wherein it provides a forming or roughing step, suitable to reduce the thickness of the thin slab just solidified, performed immediately after the casting step and before the temperature maintenance and homogenization step, the forming step or roughing step performing an adaptive reduction of the thickness of the thin slab smaller than or equal to about 65% at least as a function of the thickness, width and type of material of the finished flat product, and wherein the rolling step performs a reduction of the thickness of the rolled product emerging from the roughing step to a final thickness comprised between about 1.2 mm and about 20 mm, carrying out at most three double rolling passes.
