.160 The Ka Prebake Aluminum Technology And Control Technology Optimized

This paper in have discussed Qinghai aluminum 160 KA in advance Bei the comprehensive optimization foundation of aluminum electrolysis groove technology and control technology on, after focal point is studied with intelligent vague control technology, electrolysis the improvement of electrolysis technical condition as well as the transform of corresponding supplemental facility, research result shows:1) intelligent vague control technology can be applied successfully on the Qinghai aluminum aluminum electrolysis groove of 160KA.2) intelligent vague control technical advantage develop fully the comprehensive optimization that need to combine the condition of engineering technology , is taking this as prerequisite and have established with current intelligent vague control technical aluminum electrolysis groove the adaptive condition of engineering technology of appearance,: Low member than , low electrolysis temperature, low alumina density, the low effect coefficient of positive pole and high voltage ( high polar distance).3) the actual condition of the aluminum electrolysis research experience and Qinghai aluminum production scene of combination author many years passes through the specific enforcement for intelligent vague control technology, summarize a set of 160kA that has Qinghai aluminum characteristic intermediate next material in advance Bei the condition of engineering technology of groove.4) suit the optimization of the condition of engineering technology, it is to guarantee that intelligence is vague to control the key that technical engineering technology implements smoothly that author has at the same time also emphasized that strengthen raising and the training of staff to operate working quality and normalizes operating sequence.Through above improvement, the Qinghai aluminum electrolysis groove intelligence of 160 KA is vague to control technology to get notable increase production to have energy-saving function effect, production statistics shows that with intelligent vague control technology and coordination, the improvement of other above-mentioned aspect is rear , current efficiency can reach 93% more, ton aluminum direct current consume 13,500 kWh, with do not compare with intelligent vague control technical groove, current efficiency has raised 4 percents, direct current consume to reduce 300 kWh/t-Al, in domestic same type electrolysis groove every major economic technical index is in to be in the lead position.
