Abstract: A process and apparatus for controlling the strip run (4) of a metal strip (10) through a floating furnace (3). The strip run (4) is controlled contact-free with the aid of an electromagnetic device (1) that generates a Lorentz force acting transversely to the strip run.

Abstract: A device for joining metal strips passing successively into a strip processing plant includes two cutting punches having a respective cutting edge which is associated with a cutting edge of the respective other cutting punch. The cutting punches are movable along a cutting axis in a cutting motion to produce an undetachable join in an adjoining region by deformation. In the same position with respect to the cutting axis, the cutting edges of the cutting punches define a cutting gap which extends in the transverse direction and occupies a gap width in a width direction oriented at a right angle to the transverse direction and to the cutting axis. The cutting edges include an acute angle with the transverse direction, viewed from the cutting direction and in that the cutting punches are movable relative to one another in the transverse direction of the cutting gap to change the gap width.

Abstract: A method and a production line for producing a cold-rolled steel flat product from a hot strip with scale adhering to it and consisting of a non-corroding steel. The hot strip with scale adhering to it is cold-rolled into a steel flat product, the cold-rolled steel flat product is annealed and the annealed steel flat product is descaled. According to the invention, the cold-rolled steel flat product obtained after cold rolling the hot strip is subjected to descaling treatment in the hard-rolled state before annealing, in which the scale present on the cold-rolled steel flat product is mechanically removed. In this way, methods and production lines can be implemented, by means of which cold-rolled steel flat products can be produced cost-effectively from non-corroding steel with an improved surface finish.
