摘要： A manufacturing process for a remelt block containing aluminum designed for making aluminum alloy for the aircraft industry in which scrap containing mainly aluminum alloys used in the aircraft industry is supplied during a supply stage, the scrap is melted in a smelting furnace in order to obtain an initial molten metal bath during a smelting stage, the initial molten metal bath is subjected to purification by fractional crystallization in order to obtain a solidified mass and a bath of residual liquid during a segregation stage, and the solidified mass is recovered in order to obtain a remelt block during a recovery stage. The invention is particularly useful for the recycling of aluminum alloys used in the aircraft industry as it makes it possible to purify scrap of series 2XXX or series 7XXX alloys for iron and silicon, without eliminating additive elements such as zinc, copper and magnesium.

摘要： The invention concerns a cathode pulverization target characterized in that its active part, i.e. the volume of the target capable of being removed during the cathode pulverization, consists of a high purity aluminum alloy simultaneously containing copper and iron and having simultaneously a recrystallization temperature well above 20° C. and an electric resistivity less than 2.85 &mgr;&OHgr;.cm at 20° C.

摘要： The invention relates to a circuit for electrical connection between two successive cells of a series or row, designed for the production of aluminium by electrolysis of alumina dissolved in molten cryolite by the Hall-Heroult process at an intensity of at least 150 kA and possibly attaining from 500 to 600 kA. The circuit for the electrical supply of the cells comprises, in addition to the circuit 8 for the supply of electrolysis current, a distinct circuit 17 for correcting and balancing the magnetic fields which is formed by conductors which are substantially parallel to the axis of the series and are traversed by a direct current in the same direction as the electrolysis current which creates, in the cells, a vertical correcting magnetic field directed downwards close to the left-hand heads of the cells and directed upwards close to the right-hand heads of the cells. The total current J2 traversing the magnetic correcting circuit is at most equal to the electrolysis current J1 and is preferably between 4 and 80% of J1.

摘要： The invention concerns a process and apparatus for electrochemical measurement of the concentration of oxide ions dissolved in a bath based on molten halides. The process is based on impedance measurement at a low current and a low overvoltage, between an indicator electrode, a reference electrode and a counter electrodes. The real value Z.sub.r of the impedance is determined for two frequencies, a low frequency Zr(B) (such as 15-25 Hz) and a high frequency Zr(H) (such as 10-100 kHz); the inverse of the concentration of oxide ions is a linear function of the difference between Zr(B) and Zr(H). This method has a high level of accuracy in the low ranges of concentration of oxide ions.
