Rolling method for strip and corresponding rolling line

Abstract

Rolling method for the production of flat products with low productivity, comprising a continuous casting step at a speed comprised between 3.5 m/min and 6 m/min of a thin slab with a thickness comprised between 25 mm and 50 mm, a roughing step to reduce the thickness in at least one forming stand or roughing stand, to a value comprised between 10 mm and 40 mm, preferably between 10 mm and 30 mm, even more preferably between 10 mm and 20 mm and suitable for winding, a rapid heating step using induction in order to at least restore the temperature lost in the segment downstream of casting and in the roughing step, a winding/unwinding step in a winding/unwinding device with two mandrels, a rolling step in a Steckel type rolling unit with two reversing type stands of the product unwound by the winding/unwinding device comprising not more than three double rolling passes, or two inversions, in order to obtain a final product comprised between 1-1.2 mm and 16 mm, a cooling step and a winding step of the final product.
