ABSTRACT:
In a method for making hot strips, a workable lightweight construction steel is used which in particular can easily be deep-drawn cold and includes the main elements Si, Al and Mn, with high tensile strength and good TRIP and/or TWIP characteristics. 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 remainder being iron with the common incidental steel elements. The melt is cast in a horizontal strip casting unit, close to the final dimensions at calm flow and without bending to form a pre-strip in the range between 6 and 15 mm, and subsequently is fed for further processing.
