Classification and application of mullite insulating bricks

    Mullite insulating brick is different according to the density is divided into light and heavy mullite brick, according to the use of different temperature are divided into: 1350 mullite bricks, 1450 mullite bricks, 1550 mullite bricks etc.

    Performance and application of mullite insulating brick:
    Refractory degree is high, can reach more than 1790 DEG C. Refractoriness under load was 1600 ~ 1700 DEG C. Compressive strength of 70 ~ 260MPa. Good thermal shock resistance. Sintered mullite brick and fused mullite brick two. Sintered mullite brick with high alumina bauxite clinker as the main raw material, adding a small amount of clay or raw bauxite as binder, after molding, sintering and made. Electric cast mullite brick with high alumina, A12O3 and refractory clay as raw material, adding charcoal or coke fines as a reducing agent, after forming by reduction of electric melting method to manufacture. Crystal fused mullite than sintered mullite, thermal shock resistance than sintered products. Uniformity of content in the high temperature properties of alumina and mullite mainly depends on their distribution and glass. Mainly used for blast furnace hot blast stove top, bottom, and glass furnace regenerator, ceramic sintering furnace, petroleum cracking system dead lining.

Low Creep Mullite Brick

Composed of compound mullite, the bricks are processed through moulding under high pressure and sintering at high temperature, with Features of strong strength, steady bulk at high temperature and small creep rate, which are available for hot blast stove of large and middle size.
