Weight of light qualitative tall aluminous brick is light, heat preservation area is high temperature resistant performance is good, more expensive than brick of light qualitative clay, but use temperature is higher also. Heat preservation sex is better, it is 10 times of concrete of light qualitative heat preservation commonner. Aluminous content of light qualitative tall aluminous brick is in 40-45% above, intensity 6-7Mpa, color is whiter than brick of light qualitative clay, chosen method also is first look down on pledges whether color of surface of tall aluminous brick agrees, explain temperature fire is good consistently, additionally one kind is to measure dimension to whether accord with brick of light qualitative clay. Then section plane of will light qualitative tall aluminous brick is opened, see interior lucid. Color of inside and outside of light qualitative tall aluminous brick is consistent, intensity and heat preservation performance are good. After to prevent filling to be in furnace is used sink because of high temperature systole or vibration, make upside hollow, lose heat preservation effect, in unit process of cargo bandling, should the height according to whole boiler setting, certain distance highlights every other a bricklaying, cover gap, make come loose hot material forms a few disconnect. When hearth lays diatomite brick, every brick should join diatomite white, fill brick is seamed. Burner coping can use moulding brick or spread a heat preservation to come loose directly makings.
Pink of brick of high grade and fireproof heat preservation, press product demand proportion, join organic and compound filling, via vacuum extrusion, high temperature agglomeration and into. Heat preservation brick with its weight performance of light, heat preservation is superior, the hot face that uses extensively at all sorts of hot project facilities is fireproof line or heat-insulation layer, created a condition to raise the energy utilization rate of equipment. Brick of light qualitative heat preservation is to show density is commonly - the firebrick of G/cm3, national level measure is 230*114*65. The basis uses an environment, can choose right light simple fireproof stuff.

The heat-insulation layer of heat treatment furnace can be shaping heat preservation brick, also can be heat preservation comes loose makings, person use at the same time. Its build by laying bricks or stones builds method and firebrick identical. Heat preservation comes loose makings is main use at fill brick to seam, the aperture between furnace casing and bricklaying or laid are on vault, in order to increase the heat preservation sex of boiler setting and sealing. When fill clearance, must fill clearance, in order to ensure clearance is even fill, avoid to come loose makings the phenomenon that build canopy is formed in clearance.
The influence of structural itself. To the building of different structure, although use same data, heat preservation effect also is widely divergent. Compare with look of the fence outside concrete, the effect of same material can be reduced greatly for certain. For instance outside the window of the wall also is energy-saving transformed one part. Commonly used now new-style and energy-saving window is sure more energy-saving than old wood window effect is a lot of better. Even if better warming plate, configuration is differred in structural function, outside on the structure that the window did not transform, effect of energy-saving heat preservation also cannot be developed weller. Does aluminous factory pledge gently the discriminative: of heat preservation brick and heat preservation brick?

By its character can be divided pledge gently for firebrick of tall aluminous wear-resisting, heat insolation heat preservation firebrick, tall aluminium firebrick, tall aluminium firebrick. Phosphate is fought grinding a brick is tall aluminium model fight the typical delegate that grinds firebrick, its model delegate gets together for tall aluminium brick of smooth heat preservation (also say tall aluminium gets together brick of smooth heat preservation) , brick of argillaceous heat preservation. Fight fall off the typical delegate of tall aluminous brick is to contain zirconium to fight fall off tall aluminous brick. The dosage of tall aluminous aggregate takes tall aluminium, tall aluminium about series is pouring of makings 70% the left and right sides. Aggregate has framework effect, can affect aluminous content, intensity and fireproof sex. The main material of brick of tall aluminium of tall aluminous brick and low creep is basic and same, but still have very big difference. Tall aluminous brick is by alumina clinker is made, complementary shape with clay and additive, high temperature agglomeration and into. The characteristic of tall aluminous brick is fireproof sex tall, be able to bear or endure soda acid is eroded, thermal shock stability is good. Brick of low creep tall aluminium is a kind of advanced and fireproof material, more high temperature resistant than tall aluminous brick, tall aluminous brick has low creep better fireproof sex, thermal stability and be able to bear or endure broken bits sex.
Tall aluminous brick is in can use inside susceptive temperature limits, not easy attaint, fused. OK also and very good protection furnace casing. The build by laying bricks or stones of tall aluminous brick builds ply to also have very big effect to lining. Intake air heater and decompose furnace to use brick of 2 class tall aluminium more, use effect and tall aluminium are pouring material is basic and same. Never mind is so good those who say. Because tall aluminium is pouring,feed demand adds powdery makings and bond, the granuality classification of because this is tall aluminous aggregate will be more. The aluminous aggregate with the large size in using cooperates example type, number of two end bead is less, but tall aluminium is pouring makings granuality is more than tall aluminous brick. Grain of tall aluminous brick is 0-4 millimeter, tall aluminium is pouring feed grain is 0-12 millimeter. Phosphate combines tall aluminous brick to burn as rubbish generate electricity makings of rotary kiln line, line of the brick when opening pit is roast had warmed up fast, the refrigeration when stopping kiln is too fast, kiln skin damages. When kiln skin falls off, bricky face temperature lifts quickly ℃ of 500 ℃ ~600, make bricky body is destroyed by sex of strong thermal shock; When stopping kiln, cold air enters pit quickly inside, make bricky body temperature drops quickly, make original crackle enlarges bricky face quickly, cause blowout. Accordingly, must control the thermal shock that acuteness change causes temperature strictly.
If kiln skin temperature asks to be when 150 ℃ , achieve not easily commonly, if choose the beaverboard of close-fitting kiln skin, or do a heat-insulation layer first with heat preservation brick, cortical temperature can be reduced. But rotary kiln is one kind uses pit, rotating in the process, the liner of tall aluminous brick and heat preservation brick, go against rotate use, meeting occurrence kiln turns the phenomenon that working layer does not turn. Accordingly, two one makes the choice that heat preservation does working layer one layer also is not ideal. Thermal insulation by two layer or multilayer pledge firebrick build by laying bricks or stones is become gently, tube wall is outer for firebrick of light qualitative clay, is middle-level light qualitative tall aluminous firebrick or: of firebrick of light qualitative Mo Laishi?

The sirocco conduit of hot-blast stove includes a person in charge, canal, surround canal, join is in charge of and surround canal, director and the sirocco export that raise a canal to wait. Sirocco conduit sometimes exorbitant or conduit temperature is aglow. Also liner drops the issue of brick, cave in. Sirocco is in charge of liner to use firebrick, because place is special, the spot needs beforehand construction of the ability after build by laying bricks or stones, firebrick of layer of qualitative job of the light qualitative firebrick that liner is light qualitative thermal insulation with firebrick and worker. Adiabatic firebrick basically passes Mo Laishi to achieve the result of light qualitative heat insolation in material interior starting a hole. Accordingly, its preparation principle is will stomatic introduce material, basically include to light content law, bubble law, chemical reaction law, porous material standard, gel to note a pattern law, freeze-dry law, former the commonly used method such as a cent solution. Because shape of the method different, light content law to be able to be divided control a standard to push a law and plane. The function of adiabatic to Molaishi firebrick has different preparation technology main effect. To discuss different technology the influence of adiabatic to Molaishi firebrick, use machine pressing, crowded piece, 3 kinds of methods make foam had Molaishi is adiabatic firebrick, undertook function contrasts.
Light qualitative brick is by lime, scoria, arenaceous, fly ash, gas evolution the product of light qualitative poriferous concrete that the material such as stabilizing agent of agent, cement, bleb and conditioning agent makes. Light qualitative brick points to bubble brick commonly. This kind of brick is used at normal indoor partition, reduced the negative charge of floor effectively, sound insulation effect is good! This product is aggregate with board shape corundum and Molaishi, it is matrix with silicon line stone, join special additive to reach a few rare earth oxide to mix, high pressure shapes, high temperature is firing. Common light qualitative adiabatic firebrick includes clay, tall aluminium to bleach bead brick, low Tiemolaishi, tall aluminium to get together firebrick of smooth adiabatic firebrick, diatomite heat insolation. Tall aluminous qualitative, light qualitative adiabatic brick can be used at build by laying bricks or stones to build thermal insulation and the position that do not accept melt of strong high temperature to material is eroded and erode. When be being contacted directly with blaze, the temperature of watch surface contact of general tall aluminous qualitative adiabatic firebrick must not exceed 1350 ℃ .
