Garnet 80 Mesh Manufacturers In China

When the electrolytic cell has been running for a period of time, or the furnace bottom is found to be deformed significantly, the measurement of the furnace bottom bulge is required(garnet 80 mesh manufacturers in china). Multi-point measurement is determined according to needs (the bottom protection state diagram can be drawn according to the multi-point measurement results)(alumina grit).

If there is a crust falling into the hole, remove it (in order to prevent measurement errors); use a carbon slag arc to fish the carbon slag. Pay attention to the following measurement of the furnace bottom voltage drop, you can understand the changes of the furnace bottom(garnet 80 mesh manufacturers in china).  The reference height and the measured value of the previous furnace bottom lowering(silicon carbide powder).

Preheat the tools that need to be preheated(aluminum oxide suppliers usa), operate the exhaust air volume conversion valve (increase the air volume of the electrolysis gun), remove the tank cover at the measurement location, use the aluminum handle to grab the aluminum oxide at the measurement location(150 grit aluminum oxide), and open the diameter with the crane striking head Approximately 20cm measuring agent(garnet 80 mesh manufacturers in china).

Insert the measuring forest into the furnace(pink corundum), put a spirit level on the horizontal end of the measuring rod and make it level, confirm that the level is level, the top of the measuring rod and the cathode surface are attached, use a scale to read in a5cm unit and record the edge detection board to the measurement The distance between the bars (Y value)(garnet 80 mesh manufacturers in china). The measuring rod cannot be in contact with the anode. 

Use a crane to open about 20cam measurement(80 grit aluminum oxide blasting media), and use carbon to carry the crust and carbon slag(garnet 80 mesh manufacturers in china). Confirm the measurement slot number, prepare and check the measurement tools (the furnace should uplift the measurement rod, the scale, the distillation rake, the broom, the crane, the hook(80 grit aluminum oxide), the alkali slag step, the record book), and the cathode surface is recorded on the measurement rod at the bottom of the furnace.

Preheat the tools that need to be preheated(aluminium oxide suppliers south africa), operate the exhaust air volume conversion valve (increase the air volume of the electrolytic cell), open the grid cover of the measurement point, and use the aluminum handle to peel off the aluminum oxide at the measurement point(garnet 80 mesh manufacturers in china). If there is a crusted block falling into the hole, pull it out (to reduce the measurement error); Salvage carbon slag with carbon slag float(black fused alumina).

One point measurement is generally selected at 1/2 of the full length of the large surface on the A side (that is, at the transverse centerline of the groove). The number of measurement points can be determined according to needs(garnet 80 mesh manufacturers in china). Generally, at least 6 points need to be selected, distributed in representative places on both sides of A and B (for example(black aluminum oxide), 1V3, 1/2 and 2/3 of the full length of the large surface). 

After the voltmeter is stable, the reading is recorded in units of 10mV(alumina abrasive), and the measuring stick is slightly tilted if there is precipitation(garnet 80 mesh manufacturers in china). Connect the digital voltmeter and the measuring rod with a wire, connect the measuring rod used as the negative electrode to the negative terminal of the voltmeter, and connect the measuring rod used as the positive electrode to the positive (1000mV) terminal of the voltmeter.

Mitsubishi first inserts the measuring rod connected to the negative electrode at the junction of the cathode steel rod and the flexible bus bar corresponding to the measuring point(240 grit aluminum oxide), and then makes the measuring rod connected to the positive electrode contact the bottom of the furnace at an angle of about 45°(garnet 80 mesh manufacturers in china). In the same way as above, measure the extension height at the place where the wall thickness is 25cm(aluminum oxide blast media canada).

The purpose is to be used as the data for adjusting cell voltage, liquid height and electrolytic measures, for deciding to stop planting and for checking the deterioration degree of cathode(brown fused alumina). Stand the height measuring rod in the middle of the rollover on the flat ground, place the level gauge on the measuring rod, keep it horizontal, measure the distance from the rod to the flat ground with a scale, and record the reading in LCM(garnet 80 mesh manufacturers in china).

Take the measuring stick out of the bottom cover and place it on the ground to keep the level of the level gauge(garnet 80 mesh manufacturers in china); confirm the level of the level gauge, use a scale to read in QScm units and record the distance between the ground and the measuring stick (X value)(120 grit aluminum oxide). With the extension of the operating time, the properties of the cathode carbon block will change, which greatly increases the cathode voltage drop(glass bead blasting media suppliers).

Move the scale to the central position of the GUI edge plate, stand upright, measure the distance between the rod and the plate, read and record in LCM on the scale, the thickness of the thinnest part of the furnace side = the reading of the measuring rod, the height of the furnace side = the reading of the scale one (the height of the measuring rod is the depth of the furnace intestine)(garnet 80 mesh manufacturers in china). Check the open hole with a large structure.

Put the scale perpendicular to the inner side of the edge plate(white aluminum oxide blast media), insert the measuring rod into the electrolyte, align it with the scale at 30cm, and place the level gauge on the measuring rod(garnet 80 mesh manufacturers in china). Keep the level of the level, straighten the scale on the inner side of the rough submerged plate, read in LCM and record the scale on the full fixed rod(white fused alumina).  Therefore, Japan uses a big hook to check and measure the bottom of the hole.

Stand the measuring rod on the flat ground, place the level on the measuring rod, keep it horizontal, measure the distance from the measuring rod to the flat ground with a scale, and record the reading in LCM(100 grit aluminum oxide blast media). The thickness of the furnace side in the middle of the extension is 25cm and 30cm(garnet 80 mesh manufacturers in china); Height of furnace side in the middle of bell lift = the first reading of variable ruler (measuring rod height - furnace cavity depth).

Stop the measurement when the effect of the measured tank occurs or when the voltage to ground is abnormal(garnet 80 mesh manufacturers in china). Confirm whether the measuring rod is aligned at 30cm, stick the end of the measuring rod with the leg extension of the side furnace side, keep the level gauge horizontal, measure the height from the groove along the center of the plate to the measuring rod with a scale, and record the reading in lem(steel grid).

Insert the membrane extension end drop measuring row into the electrolyte(aluminium oxide abrasive grit), hang the end of the clock leg, and place the level on the measuring row(garnet 80 mesh manufacturers in china). The length of the extended lifting end (referred to as the secondary lifting length for short) = the reading of the measuring rod, and the height of the extended leg end = the reading of the scale one (the height of the measuring rod is the depth of the furnace face)(silicon carbide grit). 

However, the determination methods of the two kinds of determination are the same(garnet 80 mesh manufacturers in china). Precision determination is introduced(garnet sand). Keep the level of the level, measure the height of the cotton along the center of the plate to the measuring rod with a scale, read in LCM and record. Measure the leg height at the place where the furnace side thickness (including the thickness of side masonry block and tank shell) is 30cm(aluminium oxide grit suppliers). 

Before starting the new gear, the reference height of the cathode plane (the distance from the groove edge plate to the cathode) shall be measured, and the calculation results shall be archived as data as the reference value for calculating the furnace bottom uplift height in the future(aluminium oxide blast media). The measurement method is the same as that for measuring the furnace bottom uplift(garnet 80 mesh manufacturers in china). Therefore, it will not be introduced separately.
