ABSTRACT:
An apparatus serves for the continuous surface cleaning of rotationally movable casting rolls (2, 3) of a strip-casting machine. A plurality of laser beam units (25) are arranged on the circumference of the respective casting roll (2, 3), which laser beam units (25) are arranged next to one another, are distributed over the casting-roll length and by means of which the casting-roll surface (2a, 3a) can be acted upon with one or more laser beams over the entire casting-roll length. Additional cleaning units (30, 31, 35, 45) for the mechanical cleaning of the casting-roll surface are advantageously connected ahead of and/or behind the laser beam units (25). This makes gap-free and regular surface cleaning of the casting rolls possible.
