Abstract
Molten metal (15), in particular molten aluminum or aluminum alloy, is fed to the adjustable roll gap (42,44) between two casting rolls (42,44) of the horizontal strip caster by means of a nozzle which is horizontally displaceable and vertically adjustable on a carriage. The feeding of the nozzle is interrupted to exchange or clean the latter and the carriage is removed from and returned to the region of the casting rolls. The metal feed from a stationary launder into a mobile launder and/or into a molten metal distribution trough of the nozzle is continued even during interruption of the casting. A stationary launder having an outflow in the region of the end face which can be closed by an adjustable plug is arranged above a mobile launder having a molten metal distribution trough for the nozzle which is isolated via an adjustable aperture, this mobile launder being arranged on a carriage, in a manner such as to be longitudinally displaceable or longitudinally displaceable and laterally swivellable. The outflow from the stationary launder always remains above the mobile launder when the latter is longitudinally displaced and/or swung laterally.
