Abstract (en)
The invention relates to a method for the manufacture of light gauge steel strip comprising, sequentially, continually casting steel (1), cutting or shearing (2) the hot cast steel into slabs and charging into a furnace (3) which either reheats and/or homogenises the temperature and metallurgical quality of the material, descaling (4) the steel, and then reducing the steel in a roughing stand (5) and then rolling in a Steckel mill (7), or reducing directly in a Steckel mill (7) wherein the hot steel strip exits the Steckel mill (7) with a gauge of approximately 1 mm and is passed in tandem into a finishing mill (15). Zoned cooling units (14) are arranged between the Steckel mill (7) exit and the finishing mill to homogenise the temperature along the length and width of the strip and the cooling units may be adjusted to enable a wide range of entry temperatures of the strip to the finishing stand (15) such that the steel strip entering the finishing stand (15) may be in either the intercritical or ferritic phase. <IMAGE>
