Alcan Aluminum Corporation and the Great Bay, technology and management
Electrolyte additives, low molecular weight than the electrolyte can be applied. Both methods have factories in China was tested with varying degrees of effectiveness. Lithium-magnesium compound by adding electrolyte additives, are made in varying degrees to improve current efficiency reduces tank temperature effect; the use of low molecular weight than the electrolyte, most manufacturers have failed experiment,[link widoczny dla zalogowanych], only the solutions of aluminum in the northeastern state of university research results and improving processing methods under the guidance achieved some results. Foreign large-scale use of low molecular weight were pre-baked anode reason than the electrolyte is unable to meet the extensive processing operation in the low molecular weight lower than the state of electrolyte aluminum melting degrees. Resulting in reduced bath temperature, precipitation increased, the formation of disease slot. Only in the cell using a point cutting and automatic control of alumina concentration successful case in a certain range, low molecular weight than the electrolyte used and can really get the best results possible. In addition, if pursuit of aluminum fluoride, magnesium fluoride, lithium carbonate and other additives added automatically, while controlling the concentration of the provisions of its content, it may be more effective. 5.4 The steady flow due to the intelligent control technology acquisition series tank current and voltage signals to track resistance change rate calculation and control, enabling the estimation and control of alumina concentration, which requires the current series is relatively stable. Only in this way seems calculated to compare the resistance and officials close to the truth more accurately estimate and control the alumina concentration in the electrolyte: So, in the use of point-materials and intelligent control f Secretary, to use more advanced stability streaming technology to make ultra eliminate current fluctuations of the automatic control system for adverse effects. In addition, the current stability but also on the stability of electrolysis to improve the current efficiency play an important role, jumping while, but steady flow of technology to improve the level of aluminum production technology an important part. At present, Shandong Aluminum loaded with high-power thyristor steady flow of your good results and reliable operation can be considered a 6 Conclusion In summary, the side of the plug Soderberg aluminum reduction cell lies in complete mechanization and automation, and Gordon gas purification, and the realization that \Application and implementation of these technologies. Although the need to increase the number of investment funds,[link widoczny dla zalogowanych], but after the implementation of these technologies,[link widoczny dla zalogowanych], can certainly make Cecha Soderberg overall technological level to a higher level, to catch up with the technical and economic indicators advanced chu Ding baking sacrifice of these technologies by the r Nang The Ministry is also the application of transcranial baked anode, while Soderberg less than the pre-baked anode anode baking and assembly, so the cost of Soderberg still fu l to hit a large baking trough of low, open their economies are bound to loose interest _ better than pre-baked anode. : Now, for example, inserted Soderberg-point auto-cutting and intelligent control technology has reached a breakthrough fj1 『along, production and research institutes should closely throw with, cooperative research, for in this century before the breakthrough, the side of the plug White baked anode Hull in the new century. (Continued from page 36) two four-high spiral preheating machine, material exit temperature is 150 ℃. A 5o0 two KE's kneader, two vibration molding machine and a 2000t extrusion molding machine. Health anode with chain conveyor, water,[link widoczny dla zalogowanych], maintain the water temperature 25 ℃, water recycling, cooling, asked for 45 minutes. The plant has three anode baking furnace, the aluminum factory and LVL Montreal one anode baking furnace for the German cover, 52 rooms 7 box, installed furnace capacity to 140 / room, four burning aircraft, fire-burning temperature for the 125D ~ C, the upper and lower temperature 100 ℃, gas heating, infrared visit the temperature, heat consumption for the 25GJ / t anode. Burner cover for the continuous furnace, the largest peacetime service, but lower investment than open furnace, recycled tar. The other two for the pech ~ ney of the open type furnace, 6 boxes of 48 rooms, installed furnace capacity to 108 / room, fire-burning system 3,[link widoczny dla zalogowanych], heat consumption 3.5 (f1 anode, heating for 24 hours for the burner pulse. loved one anode anode system can produce 700 per week [) blocks, each weighing 900kg. Three-shift operation, five-day work week, plant manager 【4 a management: the whole plant had a staff of 200 operations [500, which, electrolysis, carbon 160, 125 maintenance personnel by management intensive ten arrows, level simplified, four vertical management level. F ¨ managers did not: the anode, roasting, electrolysis, electricity and other 10 departments, the department section chief F edge design and supervision of employees. Factory collective leadership, democratic management, merit-based, dynamic segmentation workers seek positive, computer management agency director is the entire organization, emphasis on product quality, attention to safety and environmental protection staff] a love and dedication, serious according to standard operation. Saturday and Sunday all the rest f Ling, unattended, by the workers to work consciously tons of liquid aluminum into the rate in 1000 dollars.
