Bath transfer system for receiving, transporting and conveying molten metal

Abstract

The present application relates to a bath transfer system with a vessel for receiving molten metal, a duct for conveying the molten metal from the vessel through the duct, a vessel cover for air-tightly sealing a vessel interior, and a tilting mechanism for tilting the vessel. The tilting mechanism includes at least one pedestal that is hingedly connected to the vessel, and a blocking device on the vessel for blocking the pedestal in a functional position, the pedestal being movable from a rest position into the functional position in which the pedestal extends beyond a bottom of the vessel.
