摘要： The design of a metal inert anode is proposed, it is made in the form of a perforated structure with through-openings, in particular formed by longitudinal and transverse anode elements intersecting each other and limited by the lateral sides of the intersecting anode elements, and contains vertical or inclined fins that protrude from the bath and are integrated with the anode elements or a current conductor. As a result, it ensures a reduction in the voltage drop in the anode and in the bubble layer under the anode, a reduction in the anode overvoltage and anode consumption, an increase in current efficiency and the reliability of the cryolite-alumina crust, which leads to an increase in the anode service life and promotes the formation of a reliable and durable cryolite-alumina crust above the melt surface, which improves process efficiency.

摘要： A method for preparing an aluminum-zirconium-boron alloy and synchronously preparing a cryolite is provided. The method includes the following steps: Step A: placing aluminum in a reactor, heating the reactor to 700-850 degrees centigrade, and adding a mixture consisting of fluorozirconate and fluoborate in a molar ratio of x: y into the reactor; Step B: stirring the reactants for 4-6 hours and extracting the upper molten liquid to obtain a cryolite, wherein the lower substance is an aluminum-zirconium-boron alloy, and aluminum is added in an excess amount. The method provided herein for preparing an aluminum-zirconium-boron alloy which is mild in reaction condition, easy to control and simple in technical flow can prepare a high-quality product through a complete reaction, besides, the use of the synchronously prepared low molecular ratio cryolites (KF.AlF3 and NaF.AlF3) in the aluminum electrolysis industry can achieve a proper electrical conductivity.

摘要： A raw gas collection system for collecting raw gas from a plurality of aluminium smelting pots is equipped with a plurality of branch ducts, each of which is arranged to channel a respective branch flow of raw gas from an aluminium smelting pot to a collection duct, which is common to and shared by the branch ducts. Each of said branch ducts is, near an outlet thereof, equipped with a curved section for aligning the branch flow with a flow direction of raw gas already present in the common collection duct, and a constriction for accelerating the branch flow through the branch duct outlet into the common collection duct. Furthermore, each of said branch ducts is equipped with a heat exchanger for removing heat from the respective branch flow of raw gas. The combined flow resistance of the constriction and the heat exchanger reduces the need for adjusting the respective branch flows using dampers, thereby reducing the power required to transport the raw gas.

摘要： In a method for removing a substance from a feedstock comprising a solid metal or a solid metal compound, the feedstock is contacted with a fused-salt melt. The fused-salt melt contains a fused salt, a reactive-metal compound, and a reactive metal. The fused salt comprises an anion species which is different from the substance, the reactive-metal compound comprises the reactive metal and the substance, and the reactive metal is capable of reaction to remove at least some of the substance from the feedstock. A cathode and an anode contact the melt, and the feedstock contacts the cathode. An electrical current is applied between the cathode and the anode such that at least a portion of the substance is removed from the feedstock. During the application of the current, a quantity of the reactive metal in the melt is maintained sufficient to prevent oxidation of the anion species of the fused salt at the anode. The method may advantageously be usable for removing the substance from successive batches of the feedstock, where the applied current is controlled such that the fused-salt melt after processing a batch contains the quantity of the reactive metal sufficient to prevent oxidation of the anion species at the anode.
