摘要:
Rolling method for the production of flat products with low productivity, which includes a continuous casting step at a speed between 3.5 m/min and 6 m/min of a thin slab with a thickness between 25 and 50 mm. It also includes a roughing step to reduce the thickness in at least one roughing stand to a value between 6 mm and 40 mm, and suitable for winding, a rapid heating step by means of 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. The method also includes a rolling step in a rolling unit that consists of a single reversing stand of the Steckel type to roll the product unwound by the winding/unwinding device.
