Patent

CA 2725464

A sealing device (1) is arranged around a rod electrode (4) ex-tending vertically through an aperture (3) made in the ceiling (2) of an arc fur-nace and being vertically movable inside the furnace to prevent the access of gases from the furnace through the aperture (3) to the atmosphere, and on the other hand to prevent air from flowing from the atmosphere into the furnace. The sealing device comprises a gas distribution chamber (5) provided with an inlet channel (6) for feeding essentially passive gas, such as nitrogen or air, into the gas distribution chamber. The sealing device also includes a slit noz-zle (7) encasing the electrode, through which nozzle a gas jet is arranged to be discharged from the gas distribution chamber (5) towards the electrode (4) in a direction that is at an angle (a) with respect to the horizontal plane and has a slightly upwards inclined orientation, and that is, with respect to the furnace interior, pointed outwardly, so that the sealing is carried out owing to the ef-fect of the created stagnation pressure.

Dispositif (1) détanchéité disposé autour dune électrode (4) en barre sétendant verticalement à travers une ouverture (3) pratiquée dans le plafond (2) dun four à arc et mobile verticalement à lintérieur du four pour empêcher le passage de gaz issus du four à travers louverture (3) et vers latmosphère, et empêcher par ailleurs lair de passer de latmosphère dans le four. Le dispositif détanchéité comporte une chambre (5) de répartition des gaz munie dun conduit (6) dentrée servant à amener un gaz essentiellement passif, comme de lazote ou de lair, dans la chambre de répartition des gaz. Le dispositif détanchéité comprend également une buse (7) à fente enveloppant lélectrode, et on fait en sorte quun jet de gaz soit projeté à travers ladite buse de la chambre (5) de répartition des gaz vers lélectrode (4) dans une direction qui forme un angle (a) avec le plan horizontal et présente une orientation inclinée légèrement ascendante, et qui est, par rapport à lintérieur du four, dirigée vers lextérieur, de telle sorte que létanchéité soit assurée sous leffet de la pression darrêt créée.
