Cheap White Fused Alumina Grit Suppliers Oman

When PTM has no anode positioning device, manual positioning method can be used(cheap white fused alumina grit suppliers oman). With the increase of carbon block temperature, the passing current gradually increases. After lifting the new anode onto the electrolytic cell for pole change, install the new anode in place with a level gauge(replacement of the anode later).

For the new pole with a height of 540mm, the conductivity reaches 70% of the normal value in about 16 hours and reaches the normal value in about 24 hours, and the corner anode almost doubles the time(garnet suppliers). After the new pole is cotton coated, a layer of condensed electrolyte is rapidly formed on the surface of the cold anode, which begins to melt after 1 ~ 2 hours, and the anode begins to conduct electricity(cheap white fused alumina grit suppliers oman).


Taking the self-made caliper (Pocket ruler) for anode positioning as an example, the positioning process takes the lower edge of the anode bus as the benchmark and scribes on the residual electrode guide rod(cheap white fused alumina grit suppliers oman). First, move the height (mark) on the caliper to the new pole (i.e. scribe the same height on the new pole guide rod). Only when the anode is replaced, it can be partially processed, but it is not allowed to damage the existing furnace bank(white corundum sand).


Scribe where the scale on the vertical edge of the caliper is aligned with the scribed line of the residual electrode guide rod, then draw out the caliper, scribe again 2XM below the scribed line, and erase the original scribed line(brown fused alumina). Taking 200kA pre cultivation in a plant as an example, 10 tons were injected twice, and the paste electrode was raised while pouring, so that the cell voltage remained 5.0 ~ 55v after pouring(cheap white fused alumina grit suppliers oman).


The position of this line is flush with the lower edge of the large bus(cheap white fused alumina grit suppliers oman). Some PTMs are equipped with anode positioning devices. Taking a mechanical positioning device (anode horizontal positioning instrument) as an example, it is composed of transmission belt (steel wire), dial and belt winding barrel(glass bead blasting media suppliers). One end of the belt is fixed on the anode clamp of PTM and connected to the winding Jane through the middle plate of the dial.


Therefore, when the chuck is retracted, the belt drives the middle plate to rotate, indicating different spatial positions(black aluminum oxide). The specific positioning process is: calibrate the level before pulling out the residual electrode, and lift the residual electrode to the positioning bracket of the level(brown aluminium oxide grit). Use the level to set the residual pole position, lift the new pole onto the positioning bracket of the level, and use the level to set the new pole position(cheap white fused alumina grit suppliers oman).


PTM small box fixture for production(steel grid). The wrench releases the small box fixture and slowly press out the residual electrode under the command and cooperation of the electrolytic worker. If it is found that there are crusts that may fall into the tank, command the crown block operator to suspend the pulling out, and then pull out the crusts after the electrolytic operator hooks them out(cheap white fused alumina grit suppliers oman). The anode is replaced according to a certain cycle.


After the residual electrode is pulled out, it must stand for a while until the electrolyte on the palm at the bottom of the residual electrode does not drip(cheap white fused alumina grit suppliers oman). The operator stands on the style plate and opens the fine cover plate of the pole change place: the uncovered slot cover should be neatly stacked on the adjacent slot or the left and right slot covers(pink aluminum oxide). Confirm the slot number and pole number from the operation arrangement.


Whether all foreign matters on the bus device are cleaned(aluminium oxide grit manufacturers), whether the position of the anode large bus is adjusted and whether the anode clamp is ready, etc.), inspection of the anode lifting mechanism (including lubrication of the transmission parts, inspection of the lifting operation direction and relevant indicator lights, pole loading test run, etc.), commissioning of the anode gyroscope and upper and lower limit test of the anode(cheap white fused alumina grit suppliers oman). 


The pole change is started on the second day after startup, and the aluminum is tapped on the fourth day(cheap white fused alumina grit suppliers oman). Three months after startup, it is strictly prohibited to use the multi-function unit for processing(green silicon carbide). In practice, the position of the bottom grass of the new anode is slightly higher than the original position of the bottom palm of the stump, which takes into account the hysteresis of the conductivity of the new electrode(aluminium oxide grit suppliers). 


And confirm that there is no one in the moving direction of crown block and residual pole before moving PTM(cheap white fused alumina grit suppliers oman). Switch the electrolysis push and exhaust air volume valve to the high position (increase the air extraction volume of the electrolysis cell). The length of the slit is the width of the new anode(brown fused alumina 95%). The seam is required to be connected and the liquid electrolyte in the tank can be observed(check the flexible shaft when not rotating).


Use a short steel needle or iron handle to treat the hard shell surface that cannot be processed with a wind pin to ensure that the narrow structure is connected and the liquid electrolyte in the tank can be observed(brown fused alumina mesh size F16). For the artificial opening, the gap between the rigid electrode to be replaced and the adjacent high residual electrode is prevented by the multifunctional crane for opening, and the crust of the gap is formed soon(cheap white fused alumina grit suppliers oman).


Multi-function crane (PTM) opening, command PTM to open the center seam that needs to be changed, and the crust on the side of the low residual pole side to form a narrow seam (width about & cm) that connects and can observe the liquid electrolyte in the middle(abrasive blast media). It is relatively loose, so artificial openings are used(cheap white fused alumina grit suppliers oman). The opening position is Scm outward based on the side shell line of the relatively thin and high residual maximum surface(sponge media abrasive).


After opening the mouth, instruct the crane worker to retract the striking head(cheap white fused alumina grit suppliers oman). Instruct the PTM brigade to turn the chuck, lower the clamp of the anode lifting device, clamp the hole of the aluminum guide rod of the idle pole, and lower the small box clamp of the PTM to press the hand to clamp the small box clamp(white aluminum oxide 50 mesh). Pull out the crust formed during the opening of the crown block to prevent it from falling into the electrolyte.


Use aluminum fertilizer to open the covering material on the anode to be replaced and the covering material that can be removed from the edge in a fan shape, and grab the extracted material on the inner side of the fine edge plate or shovel to the phase material pole(black silicon carbide). The numerator ratio shall not be lower than 28 within 1 month after the start-up, remain at 2.6 at the end of the second month, and remain normal in the third month(cheap white fused alumina grit suppliers oman).


Be careful not to let the crane's striking head touch the anode(cheap white fused alumina grit suppliers oman). In the process of dialing out, the space height calibration of the residual electrode on the auxiliary (the first step of anode positioning) is to calibrate the space height of the residual electrode on the plant, so that the new electrode can be accurately installed and positioned at the target height(garnet sand). The common methods of anode positioning are introduced here.


The so-called rigid pole positioning is to transfer the installation height of the anode from the stump to the new pole(corundum abrasive), so that after the new anode is installed, current test of the lifting motor, the position of the bottom palm in the electrolyte can be set according to the original position of the bottom palm of the stump(brown aluminum oxide 12 grit). The altitude remained around l7em in the month of launch, and remained normal at around 19em from the second month(cheap white fused alumina grit suppliers oman).
