摘要： This invention relates to producing aluminum by electrolysis of a melt and can be used in the process control of an electrolyte composition by quantitative X-ray phase analysis (XRD) of potassium-containing electrolyte with calcium or calcium and magnesium additives. A quantitative XRD method is employed for analyzing doped samples of crystallized bath samples taken from baths. A weighted ground bath sample is mixed with a weighted quantity of sodium fluoride at a ratio, for example, 1:2 by weight. The weighted quantities are mixed and placed in a furnace (650-750° C. for 20-40 minutes) to dissolve sodium fluoride in the sample and recrystallize the sample with the desired phase composition. The doped sample is placed in a furnace (420-450° C) and held for 15-30 minutes. The doped sample is removed from the furnace and allowed to air cool. The phase composition of the doped sample is analyzed by any quantitative X-ray phase method.

摘要： A method of taking inoperative pot online using fuse in an aluminium manufacturing plant operating on electrolysis process is disclosed. The manufacturing plant comprises of plurality of electrolysis cells or pots connected in series. Some of the pots are kept off line during start up of the plant by shorting the risers of the non running pots to the cathode bus bar (31) by shorted joints (11). The method comprises, connecting fuse assemblies in parallel with the shorted joints; inserting insulating insert plates between the risers and the short circuit bus bars and securing the insulating insert plates to isolate the short circuit bus bars from the risers (14) such that the total rated current passes through the fuse assemblies. The fuse elements in the fuse assemblies melt within about 8 to 10 minutes, completely isolating the short circuit bus bars from the risers such that the risers now feed the current to the anode assemblies of the non running pot. Feeding of charge to the non running pot is the started, thus taking the non running pot on line.
