Aluminum reduction cells lining the relationship between thermal resistance and current efficiency
LINING MATERIAL origin and different batches of attack, the thermal conductivity will have the people shown in the literature. This is based on information derived from literature data. The corresponding period from the current efficiency are listed in Table 3. Table 3 liner when the average current efficiency (% current efficiency and the thermal resistance between the bottom of Figure 2. 2002 4 45 * Light gold mirage electrical glistening Figure 2 Relationship between efficiency and thermal resistance map R - Units area of resistance, said mouth; wide an average current efficiency. with l that should also be noted that cell lined with thermal resistance is not static, as the liquid electrolyte aluminum erosion will increase the thermal conductivity of refractory materials, trough lower thermal resistance. production practices also told people that age short slot slot high current efficiency, age-long slot slot current efficiency will be reduced. This is from another angle shows the bottom of the thermal resistance between the contact with the current efficiency. 3 increase in Department of substrate thermal resistance. lower wall thermal resistance,[link widoczny dla zalogowanych], the reasons for the increase in current efficiency of aluminum according to the modern accepted theory and computer simulation results and a good cell lining design, first point to make electrolyte liquidus isotherms in the side block inside, 900 �� isotherm in the carbon cathode block layer below, to avoid the electrolyte in the carbon block solidification, resulting in carbon block damage, and second, 80,012 the isotherms should be insulating brick layer. in order to avoid thermal tiles under high temperature and damage. improve the thermal resistance of lining the bottom. reduce the wall thermal resistance, is to make the liner isotherm distribution tend to be reasonable, better way to solve the contradiction between cell insulation and heat to enhance the level of equipment. From a practical point of view, when the thermal resistance per unit area than the bottom hours,[link widoczny dla zalogowanych], bottom sediment, and thick crusts. In my factory original design structure within the village, the plane was found furnace bottom crust thickness 400mm, weighs a few tons, the production of high voltage drop in the bottom is inevitable. With the bottom of the thermal resistance to enhance the bottom to reduce heat loss, can effectively resolve the bottom sediment. to reduce the voltage drop bottom,[link widoczny dla zalogowanych], but help to reduce the temperature of molten aluminum and molten aluminum to reduce volatility and the secondary reaction of aluminum to achieve increased the effect of current efficiency. sidewalls reduce the thermal resistance, but also conducive to the formation of shell to help reduce the level of leakage current and the side phenomenon. to improve the current efficiency is also favorable, and this is the reason the current efficiency will improve. 4 Conclusion (1 ) in the electrolytic production practice, in addition to factors of production process, the current efficiency is closely related with the thermal liner. increase the thermal resistance of lining the bottom of the lower wall thermal resistance,[link widoczny dla zalogowanych], improve the current efficiency can achieve results. (2) hot resistance as an important cell lining design technical parameters can be fully utilized. With the development of the theory, the constant introduction of new materials to study the optimization of cell liner. was designed to solve the contradiction between cell heat and insulation, to achieve the desired temperature distribution, on the detours, the rapid increase level of equipment has important practical significance.

Large Prebaked production process using low-temperature, low molecular weight than the operating system is a trend. Experience has shown that early crystal electrolyte the temperature decreases, in general, the production of Aluminum & Electricity negligent is good. because it can reduce the cell operating temperature, so that the current efficiency during electrolysis. So. to establish a strict system of hot work industry, from process electrolysis technology control the temperature. (3) work to improve the quality of production processes, enhance on-site production management. computer control technology in the cell on the application, making a very long distance and cell voltage can be controlled at the same time the best and most balanced given state. which in the past can not be achieved thanks to manual control. But to maintain such control of the state, on the electrolytic production of auxiliary systems and the processes operating procedures, standardization of a higher quality requirements, on the various links The problem is not resolved, the whole can not achieve the best results. Table 4, the measured pressure drop nodes that operate for the anode and the anode assembly operations. saving potential is great. This is a requirement by technology, on-site strict quality process operation, do a good job testing the daily production and management issues. substandard quality requirements, shall not enter the next process, to strictly implement the system, enhance on-site production management. Practice Certificate sun and the moon 'to accelerate the development of enterprises, the introduction of advanced technology is only a means. so that is the purpose of localization of advanced technology. introduced advanced equipment and technology,[link widoczny dla zalogowanych], if not advanced systems and ideas management. would not give full play to its strengths. Only two closely integrated units, to produce the desired economic benefits. c responsibility I string together series of He Guangping
