    ANODE DEVICE AND PROCEDURES RELATING TO THE SAME
    CROSS REFERENCE TO RELATED APPLICATIONS [0001] The present application claims priority from U.S. Provisional Patent Application No. 62 / 396,583, filed September 19, 2016, which is incorporated herein by reference in its entirety
    BACKGROUND An inactive anode is electrically connected to the electrolytic cell so that a conductor rod is connected to the inactive anode to conduct current from a power supply to the inactive anode, where the inactive anode carries the current into the electrolytic bath to produce iron metal (where the current leaves the cell via a cathode). In some embodiments, a corrosive bath and / or vapor during operation of the cell cooperates with the anode unit and may affect the efficiency and service life of the anode unit (e.g., by weakening the mechanical connection and / or increasing the electrical resistance of the electrical connection).
    FIELD OF THE INVENTION In general, the present description is directed to a device with an inactive anode. More specifically, the present disclosure is directed to a device with an inactive anode configured to reduce, prevent and / or eliminate corrosion of the pin and / or anode material (e.g., by corrosive vapors and / or molten electrolyte) in a electrolysis cell.
    SUMMARY OF THE INVENTION Without being bound by any particular mechanism or theory, it is believed that one or more embodiments of the anode stick-protecting sealant compound of the present disclosure provide improved corrosion resistance of the anode unit when

Without being delineated by a particular mechanism or theory, it is believed that by undergoing the chemical state change to accept the fluorides, the sealing material is converted (at least partially) from a solid into a liquid material. In some embodiments, a sealing material is configured to extend between the inner surface of the hole in the anode housing to the outer diameter of the pin.

    When the anode housing is formed, the connector leg and filler materials, if used, are incorporated into the anode housing. For example, if If filler material is used (eg conductive filler material), the plug leg is located in the hole of the anode housing and the filler material (eg in the form of particulate material) is introduced into the space between the plug leg and the inner surface of the hole in the anode housing. Then, the sealing material (i.e., to provide a mechanical fastener and / or sealing the pin and / or filler material in the hole in the anode housing) is added to the upper end of the anode housing.

    While various embodiments of the present invention are described in detail, there is no doubt that those skilled in the art can devise modifications and adaptations of these embodiments. But it should be expressly understood that such modifications and adaptations are within the scope and scope of the present invention.
    Prophetic comparative example:
    Two anode assemblies (AA1 = prior art and AA2 = one embodiment of the present specification) are made with: the same anode housing dimensions and the same composition in accordance with the disclosures of U.S. Patent No. 7,507 .322 and 7,235,161; the same socket material (copper or copper alloy) and different sealing materials.
    Page 28 of 38
    DK 2019 70168 A1 In AA1 the first description (prior art) the sealing material is in accordance with the disclosure of US Patent 7,169,270. In the second description (the present description) the sealing material has 5% by weight. to 100% by weight the sealing material is moldable ceramic or metal ceramic containing Al2O3, SiO2, MgO, CaO, Na2O and combinations thereof, wherein at least some of the additives of silicate and / or aluminate in the sealing material (e.g. moldable ceramic) are replaced by a magnetite additive (f e.g., anode-matched / anode-compatible additive) configured with comparable sizing as the appropriate sizing of the additive as the additive of the prior art.
    Both anode units are configured as the embodiment of Figure 2. Both anode units were incorporated into an aluminum electrolysis cell and functioned as electrodes (anodes) extending over the bath-vapor contact surface for a sufficient period of time to evaluate if reactions occurred. result of the interaction of the reactive species in the vapor compartment of the cell with the sealant and / or its constituents.
    Anode units are pulled out of the cell and evaluated to evaluate and / or quantify the corrosion on various components of the anode device (e.g., sealing material). It will be seen that the sealing material in AA2, ie. sealant with additive specially designed (i.e., adapted) for the anode housing performed better (has less corrosion) than the known sealant. It is also evident that the socket in AA2 performed better (has less corrosion) than the socket in AA1 (the known anode device).
    Without being bound by a particular mechanism or theory, it is believed that the silica (e.g., SiO2 present as an additive in the sealing material) under the operating conditions of the cell (i.e., at high temperature and in a corrosive environment of the vapor chamber). contains
    Page 29 of 38
    DK 2019 70168 A1 reactive fluoride gas, oxygen gas and / or other reactive vapors) forms pockets of reactive silicates which can affect the reactive substances in the steam room.
    Without being bound by any particular mechanism or theory, it is believed that the reactive silicates in the additives in the sealant (i.e., AA1) will react with fluoride gas present in the vapor space of the cell which in turn forms silicon tetrafluoride which again can break down the connector. Without being bound by a particular mechanism or theory, it is believed that when the reactive silicon fluoride further affects / reacts with the pin, pockets or holes form in the sealing material (such as reducing the mechanical strength / support of the sealing material and providing pores / holes where the reactive materials can further penetrate and react with the sealing material or other components of the anode device, without being bound by a particular mechanism or theory, there are starting sites for corrosion on the socket when the silicon fluoride reacts with the socket materials, further reducing the structural integrity of the anode device and / or the electrical function of this component).
    Without being bound by a particular mechanism or theory, it is believed that the silica (e.g. SiO2 present as an additive in the sealing material) under the operating conditions of the cell (i.e., at high temperature and in a corrosive environment of the vapor chamber). contains reactive fluoride gas, oxygen gas and / or other reactive vapors) forms the magnetite additive (e.g. SiO2 and / or Al2O3 replacement in the sealing material) additive pockets designed not to cause significant reaction with the reactants (and thus neither they pore in the sealing material and / or further contribute to corrosion of the connective bone). Without being bound by a particular mechanism or theory, it is believed that the reactive silicates in the additives in the sealing material (i.e., AA1) will react with

    DK 2019 70168 A1 fluoride gas present in the vapor compartment of the cell, which in turn forms silicon tetrafluoride, which in turn can break down the socket.
