Line to produce strip and/or sheet or a combined line for strip/sheet, starting from at least one plant for the continuous casting of thin or medium slabs, the continuous casting plant comprising in sequence a continuous casting machine (12), at least one assembly (13) for shearing to size, a temperature restoration system, a rolling train (17-117) and a possible assembly (19) for the cooling of strip/sheet. A device to accelerate the speed of feed of the slabs is included downstream of the assembly (13) for shearing to size. The temperature-restoration system includes an induction furnace (14) with at least one working frequency to heat the surface and edges of the slabs, the induction furnace (14) being followed by a low-speed descaler (115) and by a tunnel furnace (16). An emergency shears (24) and high-speed descaler (15) is included between the tunnel furnace (16) and the rolling train (17-117).
Line to produce at least one of strip and sheet starting from at least one plant for the continuous casting of thin or medium slabs, the continuous casting plant comprising in sequence a continuous casting machine, at least one assembly for shearing to size, a temperature restoration system, a rolling train, and means to accelerate the speed of feed of the slabs included downstream of the assembly for shearing to size, in which line the temperature-restoration system comprises an induction furnace with at least one working frequency to heat the surface and edges of the slabs, the induction furnace being followed by a low-speed descaling means and by a tunnel furnace, an emergency shears and high-speed descaling means being included between the tunnel furnace and the rolling train.
