Abstract (en)

[origin: WO2005061152A1] The invention relates to a method for the generation of hot strips, made from a workable light gauge steel which is particularly easy to cold deep draw, comprising the main elements Si, Al and Mn, with high tensile strength and good TRIP and/or TWIP properties. The mass % are as follows for C 0.04 to < 1.0, Al 0.05 to < 4.0, SI 0.05 TO< 6.0; Mn 9.0 to < 30.0, the rest being iron with the usual elements present in steel. The melt is cast in a horizontal strip casting unit, close to the final measurements, free of bends and with a killed-flow to give a pre-strip in the range of 6 to 15 mm and then introduced to a further processing.
