General Information of Mullite Brick-MS74

Our mullite brick is a kind of high alumina refractory brick which takes the mullite (3Al2O3 · 2SiO2) as the basic crystalline phase. Alumina content is generally from 65% to 75%. Featuring high compressive strength, good thermal stability and strong impact resistance. It can be made into any specification defined by users to fit for different demands. It also has the capacity of maintaining excellent mechanical behavior under high temperature,

Applications of Mullite Brick-MS74

Our Mullite Bricks are commonly used in glass furnace, heating furnace, chemical kiln and metallurgic furnace.

CNBM has success in its refractory bricks due to their cost-effectiveness and excellent insulating properties. CNBM also has experience in refractory brick application and would like to assist you in product selection, system design, and installation techniques. We are looking forward for your inquiry.

 

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:Aluminum content 38, silicon content 55 What refractory bricks?
When the bricks are below Al2O3 71.8%, the base of the composition is mullite and SiO2, such as grade LZ-48 bricks. Because it contains a large number of SiO2 formed in the liquid phase under high temperature is 20% ~ 30%; brick in Al2O3 more than 71.8%, the excess Al2O3 formed corundum crystal under high temperature, while generating 2 high temperature phase, eutectic temperature rise by the low content of Al2O3 brick 1595 C to 1840 C, such as grade LZ-75 brick. In fact, it is impossible to produce a complete phase equilibrium in the process of production, but the glass phase is very small, and there is no more than 10% in the partial gap of the Yu Jing phase
Q:The difference between the high aluminum corundum brick and corundum mullite brick
Tiles are called floor tiles, floor tiles, polished tiles and glazed tiles are glazed tiles, bricks are samples of all kinds of tiles, ceramic tiles will be placed in the tile shop, tiles are also divided into outer wall tiles and inner wall tiles, modern brick and antique brick
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:(refractory castable, silicon carbide brick, mullite bricks etc.) do testing should be commissioned by the project? What are the specific qualification standards? Thank you
Different refractory materials have different requirements, specific industry or national standards, such as LZ can check the mullite bricks GB / standard, there should be a harvest, do testing project is in accordance with the requirements of the LZ need to determine the use requirements
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:Mullite bricks in alumina alumina is what?
Mullite (3Al2O3 - 2SiO2) high alumina refractory materials as the main crystal phase. The general alumina content in 65% ~ 75%. In addition to mineral composition of mullite, alumina containing low also contain a small amount of glass phase and cristobalite; alumina containing high also contain 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:What are the varieties of polycrystalline mullite?
Performance comparisonWe used chemical method to produce a microcrystalline structure, excellent thermal stability, temperature exceeds the 300~400. C.The small fiber diameter uniform, slag ball trace, bulk density for 1/2~1/3 products.The large amount of fiber products, high porosity, low coefficient of heat conductivity.It has large surface area, is the ideal material for high temperature catalytic carrier.
Q:Refractory bricks (mullite bricks) can be used on the walls of buildings?
Refractory bricks used in the firewall, the first choice of national standard model, its size is 230mmx114mmx65mm, model T-3, component 3.5-3.7kg, and sometimes will use refractory bricks, seven separately to make up for the effect. Refractory brick in masonry usually fireclay, refractory soil adhesion is very strong, and has a certain degree of refractory refractory, so was widely used in refractory masonry, in building fire protection requirements if the fire rating is high, to the selection of refractory masonry cement, refractory cement refractoriness of fireclay than about 500 DEG C high.
