Brown Aluminum Oxide 54 Grit Suppliers Philippines

The calculation result of the optimal height is not only related to the number of factors considered, but also to the degree to which each factor can be accurately quantified(brown aluminum oxide 54 grit suppliers philippines). However, the current domestic pole-changing cycle design should also take into account the convenience of the pole-changing operation schedule, and the increase in the pole height will also affect other aspects mentioned below(aluminium oxide grit suppliers).

Obviously, the length and width of the anode carbon block (including the cross-sectional area) will affect the following aspects(aluminium oxide suppliers south africa): Among them, the discharge of anode gas, the larger the cross-sectional area of the anode carbon block, the more unfavorable the anode gas output(vietnam aluminum oxide). The large anode bus is generally conductive and plays the role of bearing the weight of the anode(brown aluminum oxide 54 grit suppliers philippines). 


At present(brown aluminum oxide sandblasting), the anode height of the pre-melting tank in our country is generally in the range of 540~600mm, and individual companies use anodes up to 620mm(brown aluminum oxide 54 grit suppliers philippines). As early as the 1980s, Cai Taofeng used the extreme value method to obtain the mathematical expression for the optimal height of the pre-cultured anode carbon block(aluminium oxide blasting media). Therefore, it is unfavorable to the current efficiency index. 


But on the other hand, the larger the anode, the greater the degree of interference to the electrolytic cell (such as the impact on the anode current density distribution) each time the electrode is replaced(china aluminum oxide sandblasting). Its two ends and the middle power inlet point are overlapped and welded together with aluminum plates to form a bus frame, which is suspended on the screw rod (suspender) of the anode lifting mechanism(brown aluminum oxide 54 grit suppliers philippines).


Through the combination of several solenoid valves(aluminum oxide abrasive suppliers), compressed air is supplied to the shell breaking cylinder and constant volume blanking cylinder according to certain procedures to complete the sequence control of various actions(brown aluminum oxide 54 grit suppliers philippines). When the net anode consumption is 440kg / - Al, the anode bulk density is 1.5skg/em(aluminum oxide suppliers usa). And calculated the optimal height of the anode of the 160kA pre-cultivation tank to be 603nm. 


There are 28 groups of macrobenthic anodes (such as 20KA pre culture tank in China), the pole changing cycle is 28 days (one group of anodes is replaced every day in each tank), and the net anode consumption is 420kg / ton al(aluminum oxide blasting media). There are 24 groups of anodes in a large tank (such as 160kA pre culture tank in China), and the pole changing cycle is 24 days (one group of anodes is changed every day for each tank)(brown aluminum oxide 54 grit suppliers philippines).


Anode voltage drop(garnet abrasive suppliers): The anode voltage drop increases as the electrode height increases, which will increase the electrolysis energy consumption. The electrolytic cell has two large anode buses. For example, when the electrolytic electricity price increases, the optimal value of anode height will decrease(brown aluminum oxide 54 grit suppliers philippines). Obviously, the following figure shows the structural diagram of a "single block group - four claw" anode group(china brown fused alumina manufacturers).


The anode group is clamped on the large bus through small box fixtures and hanging objects on the large bus(brown aluminum oxide 54 grit suppliers philippines). The anode group is composed of carbon block, steel claw and aluminum guide rod. The carbon block is divided into single block group and double block group(white aluminum oxide abrasive 220 grit). The fresh aluminum consumes 6 wh more, and the changes of some main factors will significantly affect the optimal value of anode height(white aluminum oxide grit).


The steel claw is connected with the carbon block by phosphorus pig iron pouring, and is generally connected with the aluminum guide rod by steel explosive welding(how to choose white fused alumina). Because the anode current density is 072enm, the residual electrode height is 165mm and the current efficiency is 9%(brown aluminum oxide 54 grit suppliers philippines). The total height of anode carbon block can be calculated as 578amm (at present, the commonly used height in China is 580mmm)(white fused alumina suppliers).


Different from the single block group, the double block group uses an aluminum guide rod to connect two anodes(brown aluminum oxide 54 grit suppliers philippines). In addition, the relationship between pole changing period and anode net consumption, anode current density, anode bulk density, current efficiency and other parameters can be calculated and analyzed(wholesale brown fused alumina). The feeding device has the advantages of reliable movement, accurate blanking and long service life.


Electrolytic tracing of narrow machined surfaces is more disadvantageous(aluminum oxide blast media 60 grit). According to the number of steel claws, there are four claws and three claws. At this time, the breathable piston blocks the charging port and blocks the flow of material to the constant volume chamber(white aluminum oxide blast media), while the material in the constant volume chamber is discharged into the groove with the downward movement of the bell cover(brown aluminum oxide 54 grit suppliers philippines). 


Due to the large difference in the horizontal height of the material in the tank, some anode blocks cannot be added with alumina insulation material(brown aluminum oxide 54 grit suppliers philippines). The other parameters are the same as above(white aluminium oxide powder). Obviously, when other conditions are the same, the higher the anode carbon block, the smaller the anode gross consumption (because the residual electrode height is certain) and the longer the pole change cycle(green silicon carbide). 


The total height of anode carbon block can be calculated as 536mm (at present, the commonly used height in China is 540mm)(brown fused alumina manufacturers). When the anode in China is 540 mm high, the voltage drop of the corresponding rigid pole carbon block is about 140 MV. If the anode height increases to 610 QMM, the voltage drop of the anode building increases by about 20 mV on average(brown aluminum oxide 54 grit suppliers philippines). If the current efficiency is 93%(sandblasting sand). 


There is a suitable normal blanking interval and a sufficient amount of alumina can be quickly added when the anode effect occurs(brown aluminum oxide 54 grit suppliers philippines). Anode heat preservation (thermal balance of the electrolytic cell), the height of the anode is too high(sandblasting abrasive), which is not conducive to the heat preservation effect of the aluminum oxide covered on the rigid pole, that is, it is not conducive to the stability of the heat balance of the electrolysis(80 grit aluminum oxide blasting media).


Electrolytic planting upper structure: the greater the height of the anode, the higher the bus bar of the electrolytic cell column, the higher the position of the upper metal structure, and the greater the load(black silicon carbide). The anode replacement cycle, because the anode height is limited by many factors, can only be within a certain range, so the larger the cross-section of the anode carbon block, the longer the anode replacement cycle(brown aluminum oxide 54 grit suppliers philippines).


Whether it is in line with the principle of best economic benefits is worth further analysis(brown aluminum oxide 54 grit suppliers philippines). Extending the pole change cycle can reduce the workload and related consumption of anode assembly and anode replacement(aluminium oxide powder), and reduce the heat loss caused by the opening of the electrolyte shell due to anode replacement and the frequency of interference with the operation of the electrolysis machine by pole change(aluminum oxide blast media canada).


For example(aluminum oxide supplier), it can be pointed out when discussing the height of the anode above that extending the pole change cycle can reduce the workload and related consumption of anode assembly and anode replacement, and reduce the heat loss caused by the opening of the electrolyte shell due to anode replacement and the effect of electrode exchange on electrolysis(brown aluminum oxide 54 grit suppliers philippines). The frequency of interference in the slot operation(aluminum oxide sandblasting sand).
