The impact of distance on current efficiency. Mainly in the aluminum dissolution and diffusion loss. In the electrolysis process. Precipitation caused by the anode gas stirring of electrolytes and 135kA Prebaked caused by a defect itself, Yin,ugg milano, difference between the anode current distribution,ugg prezzo, directly increasing the volatility of aluminum tuck. Also as a low-temperature electrolysis,ugg stivali, due to the rational use of energy, reduced the loss of aluminum. The current efficiency is bound to increase. According to energy balance w: w0 + w (w - Energy Income; w - the energy needed to produce aluminum electrolysis; w - to maintain tank heat energy.) Such as current efficiency, the w increased. Revenue in the maintenance of energy unchanged, w increased the w. Is bound to decrease, then the resulting reduction in bath temperature. So. Mi revenue for the lack of thermal flutter. Increase the voltage that must be increased to supplement the energy from the pole. To avoid the appearance of the cold tank. In actual production. According to 135kA Prebaked our groove features, choose the polar distance 4.60cm - 4.80era control. Consistent with the actual production. The average tank at 4.17 ~ 4.21V voltage control is better. 4 Over the years the situation of the process technology conditions to maintain the technology over the years to maintain the conditions in table 2. 2001 6 High �� column. 1llJ ~. Chang Zhijie. Strong Zulin. Strong Zhiguang, leap kept fixed: 135kA cut baked anodes. Four low and one high. Production practices seen from Table 2, '39, I control the process conditions of process control technology becoming more and more stable. Pi Star Et5 stem major economic indicators over the years, the development trend,ugg italia, the control of the process parameters are more rational, not .... A '... ... ... due to the molecular ratio decreased, the decrease of temperature electrolysis. The level caused by shrinking over the years the main economic indicators in Table 3. Effect coefficient increased. Furnace bottom and the smaller the pressure drop increased, but production of the main feast atlas 3 years of economic indicators can be seen from Table 3, with the continuous production management norms, the current efficiency gradually increased, decreased power consumption. Before 1997, 135kA prebaked cell is the only election 9171% current efficiency, tons of aluminum DC consumption is 13566kWh/t-Al, various economic indicators are lagging behind the domestic advanced level. And since 1999, especially the implementation of the \And significantly lower power consumption. 6 economic 135kA prebaked cell, after \2.14%. If this calculation, the annual series of prolific aluminum 135000 �� 0.3355 �� 24 �� 365 �� 2.24% �� 152 �� 10 = 1290.59t, (if the cost of 11,821 yuan tons of aluminum. Priced at 16,000 yuan dollars. the direct economic benefit of up to 5,393,300 yuan.) 7 \Must ensure that adequate superheat to strictly implement the standardization of operations, strict implementation of process standards, should be proud of the result of tank system, the focus adjustment and prevention. Ensure production stability. 8 Conclusion (1) to ensure stable production, based on the molecule than in the 2.1 - 24. About the average voltage 4.2IV, electrolytic temperature 935-945 \For the current efficiency is very favorable. basically can reach 93%. (2) low production, must ensure that adequate superheat to ensure the alumina dissolution and precipitation of aluminum deposition and separation, is conducive to the improvement of power efficiency . (3) saw the production when added carbon material to return. The role of magnesium fluoride is more obvious.) adaptive control of alumina concentration control, subject to further improve control accuracy. 135kA prebaked cell is currently being developed fuzzy control technology.
