    摘要： An analysis system for determining one or more operating conditions of a metal electrolysis cell and for facilitating a response is provided. The analysis system comprises a bath probe electrically interconnected to a portable computing device. The bath probe generates signals associated with temperature measurements produced from thermal communication with an electrolysis cell bath. The portable computing device may receive these signals and generate data based thereon. The data may be transformed into operating condition information relating to the electrolysis cell.

    摘要： Molten metal is injected uniformly into a horizontal mold from a feed chamber in a horizontal direction at a controlled rate, directly on top of the metal already within the mold. A cooling medium is applied to the bottom surface of the mold, with the type and flow rate of the cooling medium being varied to produce a controlled cooling rate throughout the casting process. The rate of introduction of molten metal and the flow rate of the cooling medium are both controlled to produce a relatively uniform solidification rate within the mold, thereby producing a uniform microstructure throughout the casting, and low stresses throughout the casting.

    摘要： Stable anodes comprising iron oxide useful for the electrolytic production of metal such as aluminum are disclosed. The iron oxide may comprise Fe3O4, Fe2O3, FeO or a combination thereof. During the electrolytic aluminum production process, the anodes remain stable at a controlled bath temperature of the aluminum production cell and current density through the anodes is controlled. The iron oxide-containing anodes may be used to produce commercial purity aluminum.
