    Abstract: A metallurgical vessel (1) for molten metals includes a plurality of gas-permeable bricks (4,4',4'',...) or nozzles arranged in its wall. Each brick or each nozzle is connected to a common main feed (5) by an individual feed (6,6',6'',...) equipped with a gas flowmeter (7) followed by a control valve (8) to control the flow rate. The arrangement may be utilised to feed the bricks or nozzles differentially according to a preset programme and also to detect defective bricks or nozzles.
