Abstract
A carriage with a crucible for tapping molten metal from aluminum electrolyzers and the like includes a movable tapping tube adapted to be inserted downwardly into the metal melt from which tapping shall take place, ejector means for sucking molten metal through the tapping tube, and a discharge tube for delivering collected metal from the crucible. There may also be provided compressed air means for discharging collected metal through the discharge tube. The tapping tube is mounted pivotably substantially in an inclined plane parallel to the longitudinal axis of the carriage and extending downwardly and outwardly to the side of the carriage from a tapping opening in a tapping head located on the crucible, to which tapping head the upper end of the tapping tube is coupled in the tapping position. The tapping tube is movable under control from the operator compartment on the carriage by means of power actuator means such as a hydraulic or pneumatic cylinder or the like, whereby the lower end of the tapping tube can be directed downwardly into the metal melt of the electrolyzer at the same time as the carriage is driven to the correct position at the electrolyzer for the tapping thereof.
