<p>The invention relates to a metallurgical vessel with a heat shield placed above it and spaced from it by a peripheral air gap. At least one opening is provided in the heat shield through which a probe, lance, or electrode is inserted from the outside into the interior space of the vessel. The heat shield is surrounded by a suction hood placed around the heat shield and opened towards the bottom. The suction hood surrounds the vessel, reaching beneath the peripheral air gap. The air space formed between the heat shield and the suction hood is connected to a suction device. To create a metallurgical vessel of the kind mentioned above which guarantees the effect of suctioning off of the process gases and dust and at the same time provides an effective shield of the ambient air from the molten metal, within the suction hood (1) a partition (3) is placed projecting on the outside from the peripheral gap (2). The partition (3) forms an intake nozzle (8) with the wall (7) of the suction hood (1) which surrounds the vessel (5).</p> |
