Furnace for heating metal strips, and device and method for producing metal strips by continuous casting and rolling

A furnace for heating metal strips, comprising:

• a housing, wherein a metal strip is transported through the housing in a conveying direction, a first internal cutting apparatus and a second internal cutting apparatus are provided inside the housing, the second internal cutting apparatus is arranged at a distance to the first internal cutting apparatus and arranged downstream from the first internal cutting apparatus in the conveying direction of the metal strip, said internal cutting apparatuses are actuated simultaneously such as to separate a segment of the metal strip located between the internal cutting apparatuses inside the furnace, the housing has a discharge section with an opening designed in a lateral area of the housing or in a top cover of the housing, such that the separated segment of the metal strip is discharged via the opening out of the furnace in a discharging direction, which extends orthogonally to the conveying direction, the internal cutting apparatuses are angled relative to one another with respect to the discharging direction such that a simultaneous first cut generated by the first internal cutting apparatus that defines a first end of the separated segment and a simultaneous second cut generated by the second internal cutting apparatus that defines a second end of separated segment respectively confine an angle between 5°-15° in relation to the discharging direction in which the separated segment of the metal strip is discharged out of the furnace, and such that the angle of the cut generated with the first internal cutting apparatus is inclined against the conveying direction of the metal strip and the angle of the cut generated with the second internal cutting apparatus is inclined in the conveying direction of the metal strip.
