Arrangement for pouring a pourable melt made up of a copper alloy

When copper is melted under ambient conditions, the pourable melt tends to take up from the ambient air gases that can disadvantageously influence the material's properties. Although the pourable melt can be covered by, for example, charcoal or carbon black, experience indicates that contact with ambient air is not completely prevented. A number of possibilities have therefore been presented in the existing art in order nevertheless to prevent gas uptake from the ambient air. An arrangement for pouring a pourable melt made up of a copper alloy, which comprises a melting furnace, pivotable about a horizontal pivot axis, having a pouring tube which discharges pourable melt and through which the pourable melt can be conveyed under a shielding gas atmosphere to a filling end of a launder and can be conveyed through an outlet of the launder to a mold. The filling end of the launder is coverable by a hood that seals off the pourable melt from the atmosphere, the pouring tube engaging, with interposition of a seal arrangement, in pivotably movable fashion into the hood. As a result, the pourable melt can be transferred into the launder under a shielding gas atmosphere upon pivoting of the melting furnace and the pouring tub.
