Tall aluminous brick is to differentiate in firebrick more meticulous product, have the branch of weight, have the branch that manufactures technology, still have the branch of grade.
Brick of one class tall aluminium is made by bauxite grog, the course smashs, grading, choose and become except the treatment after iron, be called tall aluminous grain, press different grade to store. Bauxite grog and the essence of mixture clay grind a method to be able to improve product quality. When the fire in channel kiln, the temperature of the product is 1500-1600 ° C normally. This product has decrescent of high temperature squirm, corrosion resistance is strong, thermal shock stability is good wait for an advantage. Fireproof sex is in 1770 ℃ above. It is had be able to bear or endure goodly broken bits, acid-proof with alkali resistance function, use at liner furnace of all sorts of industrial high temperature, vitreous forge, cement circumgyrate furnace. Because the Al2O3 content in tall alumina product is high, because this impurity quality is small and the ply that forms Yi Rong vitreous body is lesser, because of brick of clay of prep above of temperature of this its load bate. But, as a result of Molaishi crystal does not form network structure, because of this laden bate temperature still under silica brick.
Of tall aluminous brick fireproof brick of degree of prep above clay and half silica brick, be as high as 1750? 1790 ℃ , belong to fireproof material. Tall aluminous brick is used at building blast furnace normally, hot-blast stove, electric stove supports, blast furnace, reverberator, rotary kiln liner, checker brick of type of open-hearth furnace accumulation of heat, the head of a place of strategic importance of gating system, nozzle brick. The composition of tall aluminous brick? Normally, soft qualitative clay is used at making clay of tall aluminous brick, this kind of material has good plasticity, because this is soft,clay is in normally tall alumina of the brick in making, use as adhesive. However, the free Al2O3 in the free SiO2 in clay and tall aluminous grog produces Mulite 2 times to convert reaction in 1200 ℃ , bring about bulk to expand big, silicon hole rate increases, intensity is reduced. Accordingly, the content of pink of the clay in burden should not exceed 5 ％
Basically use at lining blast furnace, hot-blast stove, electric stove supports, blast furnace, reverberator and rotary kiln. Additional, tall aluminous brick is used as checker brick of open-hearth furnace accumulation of heat extensively, the head of a place of strategic importance of gating system, nozzle brick.
Its produce process and argillaceous brick likeness. What what differ is, amount of farinaceous tall aluminous grog is very much, fireproof sex is taller than argillaceous brick, be able to bear or endure soda acid inbreaks the gender is better, because this applies to all sorts of kiln furnace firing belt. Content of Al 2 O 3 is more than a general designation of siliceous aluminous firebrick of 48 ％ to be tall aluminous firebrick. According to the content of Al2O3, can divide for 3 grade: I class (Al2O3>75 ％ ) ; I class (Al2O3>75 ％ ) ; I class (Al2O3>75 ％ ) . II class (Al2O3: 60 ％ ? 75 ％ ) ; III class (Al2O3: 48 ％ ? 60 ％ ) . Can divide by mineral composition for low Molaishi (include silicon line stone) with Molaishi (Al2O3: 48 ％ ? 71.8 ％ ) , mo Laishi corundum and corundum Mo Laishi (Al2O3: 71.8 ％ ? 95 ％ ) , corundum (Al2O3: 95 ％ ) ) with other firebrick.
How much is proportion of brick of one class tall aluminium? The Al2O3 content of brick of one class tall aluminium exceeds 72 ％ - 80 ％ . Aluminous content is higher, fireproof temperature is higher. Fireproof sex exceeds 1750 degrees. 1550 degrees are when laden bate temperature is 0.2MPa, bulk density: 2.5-2.58-2.65g / Cm3, density is high, stability is good. The weight of every brick amounts to 4.4kg, every tons of 223-227-233 piece, install in tray.
Brick of one class tall aluminium how many money one ton? According to aluminous content and accumulation density, one class cent of price of tall aluminous brick is 3 grade, from accumulation density 2.5-2.58-2.65, aluminous content 73 ％ - 75 ％ , the price is in more than 2000 - three one ton. When buying, according to surface color, accumulation density and aluminous content decide product quality is one of practical methods.
In installing a process, will secure link first 3, tilt frame 10 with perpendicular frame 4 solder together, angle iron 5 solder to go up in furnace steel structure, will fixed annulus 3 with core brick 2 place and secure, will tilt next frame 10 with angle iron join rises. Contain bolt 6, nut 7, smooth gasket 8 with bedspring gasket the steel of 9 5. Can according to the spot real measure solders declining frame 4. This practical and new-style join is worn secure the steel structure in body of heater to go up, the semicircle back-up ring that front solders 3 press in core brick closely 2 on, 2 firm ground press core brick in big brick 1 on.
Flourish Cheng Naicai regards professional fireproof material manufacturer as the home, the product is all ready, firebrick has: Quality of product of brick of argillaceous brick, tall aluminous firebrick, corundum, Mo Laishi brick is good, price of brick of one class tall aluminium is substantial, welcome everybody the incoming telegram seeks advice and choose and buy.
