Abstract (en)
Unwanted solid, non-metallic inclusions are removed from molten metal in a refractory-lined vessel by bubbling inert gas upwardly through the metal. The invention provides a gas permeable nozzle block (16) shaped to contain a nozzle (17) with a centrally-disposed through bore and to be sealingly set in the refractory lining (13) of a vessel (10) to contain molten metal, the nozzle block (16) having a gas-receiving channel (18) to extend around the nozzle (17) and means to connect the gas-receiving channel (18) to a source of gas. <IMAGE>
