Tall aluminous special shaped brick how many money a ton, why to compare brick of high aluminous fireproof mark expensive?

Because tall aluminous special shaped brick wants to compare mark brick to manufacture technology a few more complex, if be price of groovy special shaped brick,be to differ not big, how many money a ton? Because index is different, the price is in roughly more than 1000 reach four tons.
Basis of tall aluminous brick oxidizes thirdly 2 aluminium (of the how many distinction of Al2O3) content, often apply currently have 48% , 55% , 60% , 65% , 73% , 75% , 80% etc.
Tall aluminous brick is to use can bear high temperature of 1790 ℃ above and not the structure that the metalloid inorganic material of melt makes is built with fundamental build by laying bricks or stones build, it is the main and fireproof material that build by laying bricks or stones builds all sorts of industrial furnace kiln to wait for liner of hot project facilities. Press figure of face of tall aluminous brick and norms, tall aluminous brick can be divided for standard type, common model with different model (contain distinctive model, super- different) wait for a few kinds of types. Intensity of the utility as a result of all sorts of furnace kiln, heating power and hot condition atmosphere all not identical, the tall aluminous brick that needs to use makes field of dispenses physics function in the knot also each somewhat different. Boiler uses different tall aluminous brick is the hot work requirement that applies to boiler and liner of a variety of geometry body that body of each place build by laying bricks or stones asks shape goods, commonly used brand has LZ-55, LZ-65, LZ-75 3 kinds, its physics index is respectively: Fireproof degree not under 1790 ℃ ; In 1350~1400 ℃ heat preservation two hours of circumstances fall, the heavy change that burn a line is + 0.1 ～ - 0.4; Apparent pore rate all is not more than 23 ％ ; Thermal shock stability all is less than 10 times. Also have particular demand to the exterior quality of goods.  
Tall aluminous special shaped brick how many money a ton, why to compare brick of high aluminous fireproof mark expensive? Tall aluminous special shaped brick is distinguished at general firebrick, usually general brick is like ～ of standard brick, T-38, T-39, G-1 6 etc have merchandise on hand, if need is custom-built the price will be a few more expensive. 1, should doing obvious surprise firebrick first basically is to use in what place, according to material qualitative different firebrick can be divided for different clay brick, different tall aluminous brick and different silica brick, its decide according to using temperature and position, and the price of these a few kinds of different firebrick also is not identical. 2, the complex degree according to different firebrick, the price of its firebrick also is not identical, be like straight form firebrick (dimension is not GB) the price with the groove that take protruding or arc shape is different, this matters to mould cost cost and n. 3, the amount that needs tall aluminous special shaped brick is different, the price is different also. Need mixes 1000 100 pieces, the price is met for certain distinguishing, because every brick makes the same score the mould charge of booth and artificial charge,be not identical.
Quality of appearance of tall aluminous special shaped brick should achieve following requirements: (1) dimension public errand: Earth of high public errand 2 ％ ; Wedge face big head and 2mm of earth of public errand of small head width; Difference of differ in roll end diameter is worth 1mm of tolerancepublic errand earth; Earth of length public errand 1 ％ . Custom-built tall aluminous brick, big difference is earthy 2mm. (2) edge caustic. The damage that allows to heat up face or cold face to have two sides is amounted to 40mm grows and 5mm is deep; But forbid to exceed. (3) horn caustic. Cold hot side all is made only one is in horny caustic to have something made to order tall aluminous brick, horny caustic is in the sum of horny caustic length of 3 arris not to exceed 50mm. Do not exceed 20mm do not calculate horny damage. (4) break. Bricky face be patient of sends filiform tiny flaw; Not parallel of be patient of and wear away the crackle of the face; Not long at 40mm, not wide the other crackle at 0.2mm allows. (Mark of 5) indentation, frit and beat are wrapped. The diameter that allows indentation and frit mark does not exceed 10mm, big deepness 10mm; Bosomy bag does not exceed 0.5mm. The tall aluminous brick that there are all sorts of wool sides in approving a brick must not exceed the 70 ％ of gross.
Fireproof material occurrence craze, fall off, easy how to wear away to do?
