The invention relates to a device for the treatment of a stream of aluminum or magnesium-based liquid metal or alloy during its passage, comprising a ladle formed by an external metal casing, a refractory lining, a channel for the admission of the crude liquid metal at the rear, a nozzle for the casting of the treated liquid metal at the front, at least one internal partition leaving, with the bottom of the ladle, a space for the circulation of the liquid metal and defining a first rear compartment and at least one second front compartment opening into the casting nozzle. The ladle is fixed on a supporting cradle connected to an articulated frame relative to which the said cradle can rock forwards about a first horizontal axis passing through the casting nozzle, the articulated frame itself being connected to a fixed frame relative to which it can rock about the second horizontal axis. The first horizontal axis is approximately perpendicular to the stream of liquid metal. The second horizontal axis can be parallel or perpendicular to the first one and which includes a raisable cover, an immersion heater, an injector for agent for the treatment of the metal and a means 36 for alternately introducing and retracting the immersion heater and the injector.
