Now that the concept of low response coefficient has been determined, we must ensure a good electrolyte composition and reasonable oxidation phase concentration on the one hand, and on the other hand to ensure the stability of the heat balance of electrolysis planting, the standardization of the technical conditions of bridge control and the quality of operation. Through the change of the hair structure and the improvement of the shunt(corundum sand). For 320ka electrolytic tracing, the graphite rate is about 31 or more.
The low-temperature firing technology spreads you thin thickness, which is conducive to the contact between the pole faces. The maximum impulse voltage is 4.2V, and it is generally around 3.8V. Blood can avoid the redness of the shunt, and at the same time, it is a performance of energy saving. In the assembly burning test, the temperature of the low-temperature heating for 36 hours is about 320°C, which is about 0°C lower than the normal olefin image method. The generated gas particles have a high voltage.
The results show that the thickness of the furnace wall, the size of the cathode aluminum mirror, the aluminum level, the electrolyte level and the mass heat are increased(aluminium oxide suppliers south africa). The best time to reduce the voltage is a period of time after the help and pole changing, and the concentration of lead oxide is in the state of excessive processing, so the voltage reduction will not cause voltage passivity. In the electrolysis process of cryolite silver monoxide salt, the primary product of the polar reaction is CO gas.
The product is aging under the specified constant current (that is, the maximum limit current), and the aging voltage will be automatically boosted. When the voltage rises to the U value, the constant voltage starts, and the current will gradually decrease at this time. This is because the oxide film insulation resistance increases and the current gradually decreases during the repair process of the oxide film. When the aging is completed or the defective product is removed in the middle of the aging When, K must be placed in the 2 position to discharge.
Clean up the inner part of the electrolytic concentrate, remove the sewage flow on the surface of the cathode, transport the excess stone to the back for filling, and level the second half of the electrolytic concentrate according to this procedure. After the treatment, coke laying and pole hanging should be carried out on the cathode plane(aluminium oxide blast media). The difference is that there is no compressive strength in the electrolytic concentrate, and the coke laying process is not suitable Personnel operation has increased the difficulty.
The function of the reactor is mainly to absorb reactive power, and can rely on the inductance of the coil to block the change of current. In the event of a short circuit accident, the reactor can maintain the bus voltage level due to the large voltage drop on the reactor, so that the voltage fluctuation of the bus is small, and the stability of the operation of the electrical equipment on the non-faulty line is guaranteed. As an important component of reactive power compensation, reactors are indispensable for power systems.
Temperature, bus temperature, environmental temperature, humidity and cleanliness have certain requirements. Only these external conditions are kept within a reasonable range of change(brown fused alumina). When the components are installed, the bright pole must be closely attached to the heat dissipation conductor to maintain a certain pressure to prevent uneven voltage. The auxiliary equipment of the rectifier cabinet mainly includes a cooling system, a measurement and control system, a deionized water system, and a support bracket.
The design purpose of position B in the figure is mainly to consider the strength of the convex part. In the sintering start-up and production process, the negative grade block has to go through the high temperature and rapid transformation process, and the convex part is easy to break. The initial burning of coke particles is to lay a layer of 2-3cm thick coke particles between the cathode and the anode, and then apply a series of current to achieve the purpose of color and heat sintering.
The 10 years after China 3000 is also the 10 years in which China’s electrolysis capital model has advanced rapidly. In just 10 years, 200 kA, 320kA, 350 kA. 400 kA and 500kA extra-large pre-junction anode electrolyzers have been developed(white fused alumina). However, there are also many problems in the development, such as excessive production capacity and certain overhangs in individual indicators, high operating costs and tight power supply, and other issues still test the development of China’s electrolytic aluminum technology.
In the process of electrolysis, the electrolysis tends to be dry to better control the moisture of the negative carbon block. The formation of miscarburization not only causes visual loss of aluminum, but also has a serious impact on the production process. The existence of phosphating button is also one of the main reasons for the damage of the old electrolytic cell. Mainly the generation of carbon monoxide and the discharge of ammonia ions are simplified forms. The sophisticated device of the electrolytic capacitor is shown in the figure.
