Product Description

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.

$Mullite Bricks Refractory Bricks Refractories$

Q: (refractory castable, silicon carbide brick, mullite bricks etc.) do testing should be commissioned by the project? What are the specific qualification standards? Thank you: Compressive strength, volume density, flexural strength, thermal shock resistance, high temperature load, creep temperature, refractoriness, etc.. There should be GB

Q: What are the properties of corundum mullite?: Heavy material has good compactness, high compressive strength, resistance to various corrosive gases, good thermal shock resistance, good thermal conductivity and wear resistance.

Q: What is the price of refractory bricks?: The construction is superior, the light insulating brick has good machinability, and the construction is convenient and simple, and the labor intensity can be reduced, the construction efficiency can be improved, and the construction period can be shortened. The price is determined by the choice of material and volume density, from several hundred to 5000 yuan, mainly with the choice of material

Q: Mullite bricks in alumina alumina is what?: Quality solutionsMullite brick:With mullite as main crystalline phase of high alumina refractory products. Mullite bricks containing Al2O3 64%~75%, refractoriness >1790? C, normal temperature compressive strength 70~260MPa, softening the starting point for 1600~1700 degrees. The manufacturing method for casting and sintering process.

Q: Jm26 mullite aluminum content in the number, ask God to answer. 23 more. How is this identified with the naked eye?: Under strong alkaline conditions, aluminum is separated from other metal ions by the amphoteric nature of aluminum.

Q: The introduction of mullite brick: General alumina content in 65% ~ 75% between. In addition to mullite, the mineral composition contains lower amounts of glass phase and square quartz, and alumina containing a small amount of corundum.

Q: Mullite brick: High refractoriness, up to 1790 degrees celsius. The softening start temperature is 1600~1700 degrees. The compressive strength at normal temperature is 70 ~ 260MPa. Good thermal shock resistance. The sintered mullite and fused mullite brick two. Sintered mullite brick with high bauxite clinker as the main raw material, adding a small amount of clay or raw bauxite as binder, after molding, sintering and made. Fused mullite brick with high bauxite, alumina and refractory clay as raw material, adding charcoal or coke fines as a reducing agent, formed by reduction of electric melting method to manufacture. The crystallization of fused mullite is larger than that of sintered mullite, and the thermal shock resistance is better than that of sintered products. Their high temperature performance mainly depends on the content of alumina and the uniformity of the phase distribution of mullite and glass. [1]

Q: The difference between the high aluminum corundum brick and corundum mullite brick: Wall tiles and floor tiles are collectively referred to as ceramic tile flooring

Q: What are the varieties of polycrystalline mullite?: PNF-100 seriesThe PNF-100 series are made of polycrystalline mullite fiber cotton felt to cut, compress, and wrap into blocks without any adhesive.Characteristic: thermal shock resistancelow thermal conductivityLight weightSound absorption propertyLow thermal storage

Q: Refractory bricks (mullite bricks) can be used on the walls of buildings?: Mullite refractory bricks can be used in construction, but their price is too high. We choose high alumina brick to meet the demand.
