Patent ID: 7591300

Claim:
A method for producing a cast metal strip from a melt space fed by a metal melt, two opposing casting rolls and two side plates at opposite ends of the two opposing casting rolls together defining and enclosing the melt space and further defining a casting gap leading out of the melt space, the method comprising: feeding the metal melt into the melt space for forming in the melt space a melt bath with a bath surface open on top, and delivering the cast metal strip out of the melt space through the casting gap; forming a delimited surface region on the bath surface for collection of particles foreign to the metal melt being formed, the forming of the delimited surface region performed under an action of at least one gas jet directed onto the bath surface, the at least one gas jet having a jet axis that intersects the bath surface at a distance from a first contact line between the bath surface and one of the casting rolls, wherein an entirety of the at least one gas jet avoids directly striking the casting rolls and the at least one gas jet strikes the bath surface with the jet axis at the distance of from 10 mm to 50 mm, measured on the bath surface, from the first contact line.
