- the roller temperature in front of the multi-stand finishing train can be selectively adjusted by the arranged behind the roughing device for cooling, heating or holding the temperature of the hot strip either austenite or ferrite or in the transition region from austenite to ferrite.
- a method for producing hot strips of lightweight steel is known, which is particularly well cold deep drawable and having as main elements Fe, Mn, Si and Al.
- the pre-band produced by tape casting first passes through a device under protective gas for homogenization in connection with optionally holding the temperature, cooling or heating. Thereafter, the pre-strip is subjected to at least one pass hot rolling process with a Rescueumformungsgrad of at least 50%. After the last stitch, the hot strip is cooled and rewound. Depending on the ratio of casting to rolling speed, the hot rolling process takes place inline or decoupled.
- the homogenization zone is intended to effect temperature equalization across the hot strip area and stress relief within the hot strip, regardless of whether the temperature level is maintained, increased or decreased.
- the casting process there is a direct connection between the material in the liquid phase in the area of the melt application and the further process steps of the solidified material via the casting belt.
- the casting belt is fed via a transport line for further processing.
- the further process steps can be: straightening, rolling, cutting and winding (reeling, coiling).
- This and other components of a casting plant can lead to tensile and mass flow fluctuations in the casting belt. If these disturbances continue in the direction of the liquid steel, casting defects and adversely affecting the casting belt may occur, such as thickness variations, overflows, edge constrictions and belt or stall separation.

- the casting process is decoupled from the rolling process.
- the casting speed can be selected as a function of the course of the solidification process of the melt and, on the other hand, the hot rolling process can take place at a defined hot-rolled strip temperature until a predetermined degree of deformation is achieved.
