Abstract: A single treatment compartment has a liquid metal inlet and outlet and a connection to a liquid metal-input trough. A treatment gas is injected into the liquid metal arranged in at least one sidewall of a ladles. The liquid metal inlet and outlet have an orifice positioned so as to be entirely underneath a level of the liquid metal during the treatment, in order to prevent entry of ambient air into the compartment during treatment. The treatment compartment includes an upstream part and a downstream part. The gas injection is accomplished in the upstream part. The compartment further has a filter located in the downstream part for degassing and filtering the liquid metal. Injection and filtration occur in close proximity to one another and within the same single treatment compartment.

Abstract: A device for the treatment of a liquid metal flow comprising a treatment ladle, wherein the ladle comprises: a treatment compartment, liquid metal inlet means and outlet means, connection means to at least one liquid metal input trough, at least one liquid metal output trough, and means of injecting a treatment gas into the liquid metal arranged in at least one sidewall of the ladle, wherein the liquid metal inlet and outlet means each comprise at least one orifice positioned so as to be entirely underneath a level of the liquid metal during the treatment, in order to prevent entry of ambient air into the compartment during treatment, and further wherein the treatment compartment comprises an upstream part and a downstream part, and the injection means is located in the upstream part, and the compartment further comprises at least one first filtration means located in the downstream part.

Abstract: The invention is directed to a nozzle for feeding liquid metal to a moving mold of a continuous sheet casting machine, such as continuous casting between cylindrical rolls rotating about a horizontal axis. The nozzle is characterized by cheeks the inner side walls of which extend beyond the orifice initially by a straight element which can be composed of several parts then by a portion that is tapered to diverge from the nozzle axis at an angle of 5.degree. to 15.degree.. These cheeks may be strengthened in order to resist the strains caused by the solidified metal, and they may be provided with cooling or heating means. They are mounted to extend either into the area between the cylindrical rolls or to terminate outside their rolling area.
