Abstract: A twin roll caster and a method for operating a machine of this type. The machine includes two casting rolls, that delimit a casting gap between them on its longitudinal sides; two side plates that delimit the casting gap on its narrow sides; and at least one oscillation device, which moves the side plate in an oscillating manner about an axis of oscillation, extending substantially axially parallel to the axes of rotation of the casting rolls. Oscillation device includes two actuators, which are articulatedly coupled to the one side plate and each apply a torque rotating about the axis of oscillation on the one side plate, and a control device that emits control signals, upon which the actuators, individually or together with each other, carry out adjustment movements aligned against one another or parallel to one another.

Abstract: A method for operating a two-roll casting machine for casting molten metal into cast strip, which machine has two casting rolls which are each rotatively driven in opposite directions about an axis of rotation and between them delimit a casting gap on its longitudinal sides, with side plates that can be placed on the casting rolls, which side plates seal the casting gap on its narrow sides in the casting operation, bridging the casting gap with a refractory material, wherein the side plates are moved during the casting operation in a direction which is aligned parallel to the direction of conveying in which the cast strip leaves the casting gap. With such a method the formation of grooves distorting the casting result and the casting operation can be suppressed with increased certainty and the service life of the side plates can be increased, compared to the prior art.

Abstract: A twin roll caster and a method for operating a machine of this type. The machine comprises two casting rolls that delimit a casting gap between them on its longitudinal sides; two side plates that delimit the casting gap on its narrow sides; and at least one oscillation device, which moves the side plate in an oscillating manner about an axis of oscillation extending substantially axially parallel to the axes of rotation of the casting rolls. The degrees of freedom of the side plate movements are increased because the oscillation device comprises two actuators which are articulatedly coupled to the respective side plate and each apply a torque rotating about the respective axis of oscillation on the side plate and a control device that emits control signals, upon which the actuators individually or together with each other, carry out adjustment movements aligned against one another or parallel to one another.
