Density of tall aluminous brick, it is bulk density namely, it is one of referenced index that judge quality of tall aluminous brick. The bulk density of tall aluminous brick uses G/cm³ or Kg/cm³ expresses. According to GB regulation, density of tall aluminous brick differs according to aluminous content also somewhat difference, between 2.3~2.6. The density of tall aluminous brick is right other a lot of function have distinct effect, like porosity, intensity, fight temperature of bate of aggressivity, loading, wearability, heatproof shake to wait. To light qualitative tall aluminous brick, get together like tall aluminium light brick, bulk density and its thermal conductivity and thermal capacity also have close relationship. Generally speaking, the bulk density of tall aluminous brick is high, to its intensity, fight temperature of bate of aggressivity, wearability, loading more advantageous.
Tall aluminous brick belongs to neuter and fireproof material, by aluminous alumina or other alumina content more expensive stock is made shape fire and those who become. Have thermal stability tall, fireproof temperature orders about in 1700°C, use at the liner of electric stove of rotary kiln of vitreous forge, cement, steel-making. Of course still a few have Gao He the brick of tall aluminous clay of soft, low creep, small air hole, finished product of tall aluminous brick.
Main use:
Build by laying bricks or stones builds liner of furnace of roof of furnace of boiler of kiln of blast furnace, cement, power plant, hot-blast stove, coal fines, electric stove, blast furnace, reverberator, chain, rotary kiln. In addition, tall aluminous brick still uses brick of mouth of the head of a place of strategic importance that becomes checker brick of type of open-hearth furnace accumulation of heat, gating system to use, water to wait widely.
Tall aluminous brick is had apply quality goodly, fireproof degree tall, apply life to grow wait for characteristic, it is the firebrick goods with most wide application of industrial kiln furnace. Tall aluminous brick is used at liner of roof of steely, steel-making, hot-blast stove, electric stove, blast furnace, reverberator, rotary kiln to wait for industrial kiln furnace commonly, its are main raw material is line of silicon of; of tall aluminous aluminous grog stone a group of things with common features is mineral (include stone of line of cyanite, red cornerstone, silicon to wait) ; constitutes material artificially, wait like corundum of frit of Mo Laishi of industrial alumina, composition, report. How the stand or fall of brick of tall aluminium of naked eye resolution?
1, colour: When buying tall aluminous brick, principal should see color, surface of exceedingly good tall aluminous brick is lubricant, what colour fizzles out is hoar, quadrilateral evenness, do not have horn, without break.
2, heft: Want to call single block bricky heft, by heft standard heft of brick of one class tall aluminium is 4.5 kilograms. Heft of brick of 2 class tall aluminium is 4.2 kilograms, heft of brick of 3 class tall aluminium is 3.9 kilograms, equal grade, equal parameter type can arrive at this standard can regard as exceedingly good tall aluminous brick, contrary short of of this heft clarify quality is good.
3, exterior quality: ? Does chasm of administer of of Huang Jian of dispatch of admire of exhausted of salt of laborious of bell of cease Shou ⑾ identify fine crotch of delay of dispatch of the larva of a tapeworm or the cercaria of a schistosome of obstruct Xi the Tang Dynasty two?
4, different cent is aluminous content of basis of tall aluminous brick brick of tall aluminium of brick of brick of 3 class tall aluminium, 2 class tall aluminium, one class and fancy tall aluminous brick, the tall aluminous brick of same type dimension contains aluminous amount taller, bulk density is higher, sheet also is jumped over again tall, this also is to use one of levels that measure bricky quality stand or fall.
