Abstract (en)
[origin: FR2766209A1] The invention concerns an inert tank for treating an oxidable liquid metal (3), comprising a metal tank body and lid internally protected with an inert refractory lining (1, 13), said tank body comprising a plurality of inlets and outlets (17) for the liquid metal such that they avoid all contact between the liquid metal (3) placed in the tank and the external environment, the inerting system comprising at least two of the following devices: a) an additional sealing shell (4, 15) enclosing the tank body metal wall (2, 14), the resulting double additional shell containing a dry gas; b) an inflatable joint (20) between the lid and the tank body; c) sealing means (34-36, 40-46) on the assembly of removable and/or movable auxiliary equipment (gas injector, heating element, thermo-elements and others) passing through the lid and optionally a pressure regulating device (25-27) for adjusting the internal pressure to a value higher than atmospheric pressure.
