High heat refractory kiln furniture Mullite lightweight insulation brick 230 * 114 * 65mm
1. Description
Mullite (3 2 sio2, al2o3) phase of high aluminum refractory material. General alumina content is between 65% ~ 75%. Mineral composition in addition to the mullite, contain the alumina lower also contains a small amount of glass phase and cristobalite; Containing alumina high contains a small amount of corundum.High refractoriness, can reach more than 1790 ℃. The rul start temperature of 1600 ~ 1700 ℃. Room temperature compressive strength of 70 ~ 260 mpa. Good thermal shock resistance. A sintered mullite bricks and two fused mullite brick.
Sintered mullite brick with high bauxite clinker as the main raw material, add a small amount of clay or raw bauxite as binder, forming, sintering and made. Fused mullite brick with high alumina, alumina industry and refractory clay as raw material, adding charcoal or coke fine as a reducing agent, reduction fused method is used to manufacture after forming.

3. Features
Low Thermal Conductivity
It has good insulation effect and can thin the thickness of furnace wall.
Low thermal capacity
Less heat storage, it has good usage effect in intermittent furnace.
Good thermal shock resistance and high temperature strength
It can prolong the service life of kilns and prevent dirty slag to drop down.
Precise dimension
It can keep uniform gaps between each brick, speed up the building, guarantee the integrated high strength of the masonry.
Low impurity
Lower iron and alkali content, it has high resistance to reduce atmosphere corrosion at high temperature.
4. Application
It is mainly used for hot blast stove top, blast furnace and furnace bottom, the regenerator of glass furnace, ceramic sintering kiln, petroleum cracking system corner lining, etc. Also widely used in hot blast stove, metal furnace, ceramic tunnel kilnelectrical porcelain shuttle kiln, etc., has a broad market prospect.
