The stirred castable should be poured into the mold immediately (multi-point feeding is better), vibrate with an insert vibrator, and report until the surface is exposed to floating water(aluminium oxide suppliers south africa). When lifting the vibrator, avoid leaving a cavity, and the vibrating rod should move slowly and evenly, and cannot be moved for a long time at one point to prevent segregation of the castable(high quality white aluminum oxide grit suppliers). 


Different manufacturers have different standards for impermeable and heat-insulating refractory castables (refractory concrete)(high quality white aluminum oxide grit suppliers). When adding the second layer of material to vibrate, do not insert the vibrating rod into the first layer of material to prevent damage to the structure of the first layer of initially set material layer(white aluminum oxide abrasive 220 grit). If carbon blocks are used for the side blocks, see "Making of Mingji Carbon Block Group".


If the ambient temperature is greater than an average of 20C days, the curing time is 24 hours, otherwise it is 48 hours(80 grit aluminum oxide blasting media). The surrounding shell is made of asbestos board and calcium silicate board, and the gap is less than 2mm. After pouring, the full height climatic slope is not more than 5mm, and the surface unevenness is not more than 2mm(high quality white aluminum oxide grit suppliers). The mud is full, ready for the side carbon block of masonry(white aluminum oxide blast media).


Type D corresponds to the full-length carbon block, which has the least number of joints(high quality white aluminum oxide grit suppliers). When the fire bricks hold the pouring body during the masonry, after the curing time is reached, the pouring body is leveled with refractory mud to build one or two layers (depending on the inner village map) 6Smm high alumina brick or clay Insulating refractory bricks, the brick gap is less than 3nm(aluminum oxide blast media). 


Two-carbon steel rods are used to build 6Smm clay heat-insulating refractory bricks (two or three layers, depending on the inner village surface), which is wetted, and the brick gap is less than 3m(aluminum oxide suppliers usa). The castable is supported by the template according to the size of the inner village diagram, and the cathode carbon block is fixed around it(high quality white aluminum oxide grit suppliers). The table shows the composition and performance of one of them(sandblasting abrasive).


The main material for the installation of the cathode carbon block group(high quality white aluminum oxide grit suppliers). After greasing the rod hole, the carbon block group shall not move(china brown fused alumina manufacturers). If you need to add strips, add strips on the third block on both sides of the corner, and the size of the strips should not be less than one-half of the original carbon block(aluminium oxide grit suppliers). If it is a carbon block, use alumina, or carbon glue or side heat dissipation filler to fill it. 


Wooden hammers should be used for masonry and adjustment of the side carbon blocks. Starting from the corner, vertical seam is less than Q5mm, horizontal seam is less than 3mm, and the offset is less than 5mm(how to choose white fused alumina). The back of the side block is close to the lattice steel plate, and the back seam is less than 2mm. After pouring, cover the pouring body with a straw bag and keep it in good health(high quality white aluminum oxide grit suppliers). 


Metal hammers are strictly prohibited to strike to prevent damage to the carbon blocks(high quality white aluminum oxide grit suppliers). The steel bars at both ends of the carbon block group shall be pre installed with baffles(brown aluminum oxide sandblasting). The masonry blocks (carbon blocks or silica bricks) should be carefully inspected, and the defective ones should be placed in the corners according to the situation(garnet abrasive suppliers). The large surface can be built into an arc according to the vertebral shape.


Use a mixer to dry mix the castable for 2 minutes(china aluminum oxide sandblasting). Before rebuilding, clean the dirt on the tank shell and the mud on the surface of the surrounding bricks. If silicon carbide bricks are used, the silicon carbide remains fired(aluminum oxide abrasive suppliers). When using silicon carbide bricks on the side, silicon carbide refractory mud is used(high quality white aluminum oxide grit suppliers). The table shows the main physical and chemical performance indexes of a silicon carbide refractory mud.


General sodium silicate water glass(white aluminium oxide powder): water glass conforming to national standard GB / t420296, density: 1.32 ~ 138gcm, waviness (20) (be) 35-37, modulus (m) 3.53.7(high quality white aluminum oxide grit suppliers). For example, clean the surface of the built comb bottom (thousand type impervious material), and carry out the installation operation according to the pre drawn operation datum line, subject to the center of the groove, from the center to both ends(aluminum oxide blast media 60 grit).


It is strictly prohibited to damage the carbon block, pin rod and baffle(wholesale brown fused alumina). The installation shall be stable, and the uneven part can be leveled with powder (impervious material). When lifting the carbon block with copper wire rope, preventive measures must be taken at the pressed part to prevent damage to the carbon block(high quality white aluminum oxide grit suppliers). The spacing of carbon blocks shall meet the requirements of the lining drawing(vietnam aluminum oxide). 


The combination of the material with low graphitization or low graphitization carbon blocks can significantly improve the sodium expansion resistance of the cathode, while the combination with high graphitization or high graphitization carbon blocks can significantly improve the unit resistance of the cathode(green silicon carbide). When adjusting the carbon block group, only pry the carbon block, not the steel bar(high quality white aluminum oxide grit suppliers).


The water glass putty shall be clean and shall not be mixed with foreign matters(high quality white aluminum oxide grit suppliers). When in place, the steel bar shall be placed in the center of the window, and the deviation between the center line of the cathode steel bar and the center line of the slot shell window shall be ± 3mm(brown fused alumina manufacturers): the cathode steel bar baffle shall be close to the copper plate of the slot shell, and the 2 ~ 3mm gap shall be filled with glass asbestos putty(aluminum oxide sand).


The performance indexes of asbestos carding are shown in the table, and the stone grid adopts warm asbestos machine to select level 4(black silicon carbide). Technical properties of asbestos powder: 10% short fiber stone lattice, 0% fine calcium magnesium powder of light refractory soil, system density Q8% em, heat resistance not less than 600 ℃(aluminum oxide grit), moisture not more than 5%, and thermal conductivity not more than 0.093wmlk(high quality white aluminum oxide grit suppliers). 


If it needs to be moved, the ratio of plug and water glass asbestos putty sealing material in the window hole gap shall be(high quality white aluminum oxide grit suppliers): water glass: (asbestos powder 706 + asbestos line 30%) = 1:1.5, which shall be mixed evenly. Then remove the template and temporarily round it with a wooden template(white fused alumina factory). Add clean tap water (the amount of water added is between 65~7.5%), after adding water, stir for 3-4 minutes to discharge. 


If it cannot be corrected, it must be replaced(aluminum oxide blast media canada). It is considered that this type can minimize the possibility of electrolyte and liquid aluminum leakage and the possibility of mechanical damage caused by lifting force and pushing force(aluminum oxide sandblasting sand). The full-length carbon block does not necessarily use the full-length cathode rod, but the development trend is the full-length carbon block and the full-length cathode rod(high quality white aluminum oxide grit suppliers). 


The horizontal height difference of adjacent carbon blocks shall not exceed 3mm, and the length deviation shall be ≤ 10mm(aluminum oxide supplier); According to the fiber length and content of grade 4 asbestos, it is more than 5 ~ 35% at 4.8nm, more than 45 ~ 70% at 1.35mm, and the content of sand dust is not more than 55%(high quality white aluminum oxide grit suppliers). The deformed rod hole baffle can be used only after being corrected(sandblasting sand). a. Compared with B and C, type C is the best.
