$High Alumina Brick SK38 - High Quality Refractory Material$

$High Quality Corundum Brick - Purity Corundum Refractory Bricks$

In 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.The crystallization of fused mullite is bigger than sintered mullite,

thermal shock resistance than sintered products.Their high temperature performance mainly depends on the content of alumina and

the uniformity of the distribution of mullite phase glass.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.

Q: Aluminum content 38, silicon content 55 What refractory bricks?: Semisilica brick: the content of Al2O3 is 15% ~ 30% of aluminium silicate refractory products. Manufacturing products are semi silica quartz containing impurities or native clay kaolin, refractory clay or kaolin beneficiation tailings and the pyrophyllite

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: Is there a mark on the contract? Mark the items as required by the contract.

Q: What are the properties of corundum mullite?: Lightweight materials have uniform internal structure, high compressive strength, corrosion resistance, heat shock resistance, oxidation resistance, high temperature and low thermal conductivity.

Q: What is the price of refractory bricks?: The refractory insulating brick generally refers to light brick, normal furnace lining are using this brick kiln will not increase the weight, and good heat insulation effect and ordinary insulating brick production are made of clay, high alumina high strength low iron bead brick, mullite, high aluminum light insulating firebrick, diatomite insulating refractory brick, the use of light heat insulation brick can increase the use of space, and good insulation effect

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?: In the presence of excess EDTA in the acidic medium, the aluminum is complexed with EDTA, and the remaining EDTA is complexed with lead salt, and then the EDTA complexed with aluminum is replaced by sodium fluoride, and the lead salt is substituted...

Q: The introduction of mullite brick: High alumina refractory with crystalline mullite (3Al2O3, 2SiO2) as the main crystal phase.

Q: Mullite brick: High alumina refractory with crystalline mullite (3Al2O3, 2SiO2) as the main crystal phase. 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: 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: Refractory bricks (mullite bricks) can be used on the walls of buildings?: In many architectural design, high-rise fire rating is placed in the important position of the topic, especially when the floor height is more than 20 layers, we have more stringent requirements for the choice of fire resistant materials. The building wall, kitchen flue, boiler flue, flammable zone must use a firewall barrier, in many refractory refractory brick is the product of choice for fire resistance of refractory brick masonry is more stable.
