Brick of low creep tall aluminium and common distinction of tall aluminous brick

Brick of low creep tall aluminium and common tall aluminous brick comprises in material and are a few distinctions on function:
Material composition: Common tall aluminous brick: Common tall aluminous brick basically is mixed by alumina a few composition of additive of siliceous aluminous etc. Brick of low creep tall aluminium: Tall aluminous brick is in low creep common the additive that certain amount added on the foundation of tall aluminous brick, in order to improve its creep performance. Different creep temperature is added those who differ is beneficial and mineral the denaturation fighting squirm that can raise tall aluminous brick can. When 1550 ℃ , 1500 ℃ when creep temperature accretion is quartz, 3 stone mineral. 3 stone are to point to cyanite, andalusite and silicon line stone. It is when creep temperature when 1450 ℃ , 1400 ℃ , 1350 ℃ , accretion is 3 stone mineral, corundum, active alumina. When creep temperature is 1300 ℃ , 1270 ℃ , 1250 ℃ , add 3 stone mineral.
Creep function: Common tall aluminous brick: Common tall aluminous brick may appear below high temperature the creep of certain level, be in namely continuously below high temperature action, bricky material can happen be out of shape. Brick of low creep tall aluminium: Tall aluminous brick passes low creep add specific additive, can reduce the vermicular phenomenon below high temperature significantly, increase the stability that its issue in high temperature environment.
Use a field: Common tall aluminous brick: Common tall aluminous brick applies to furnace of general kiln of high temperature industry, wait for a domain like metallurgy, chemical industry. Brick of low creep tall aluminium: Tall aluminous brick applies to low creep to ask to creep function taller circumstance, if the need such as vitreous kiln furnace, cement kiln furnace is long-term,high temperature stabilizes the facility that run.
Brick of low creep tall aluminium is opposite at common tall aluminous brick has distinct advantage on creep function, apply to equipment of higher to creep performance demand high temperature industry, but normally for, the manufacturing cost of brick of low creep tall aluminium is higher, because this is in actual application,need undertakes choosing according to particular case.
