Specifications
Refractory brick is a kind of insulation material adoption organic matter as ignition loss substance
in order to increase the porosity, small volume density , good insulation effect, high mechanical
intensity , small thermal conductivity and low heat storage. They are widely used in Fire – Clay
Insulating Refractory Brick, High-Alumina Insulating Refractory Brick , Diatomaceous Insulating
Brick, High Grade Insulation Brick :XJM Series Light-Weight Insulation Brick , B Series Thermal
Insulation Brick, Calcium Silicate Insulating and Refractory Products, Clay Insulation Brick, Foam
Diatomite Insulation Brick, and Light –Weight Insulation Brick.
Lower heat storage than denser refractories

- 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: (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: What is the difference between mullite ceramics and alumina ceramics? Can you tell me something to do with floor tiles?
- The floor tiles are not made exclusively of alumina. Pure alumina ceramics are expensive.
- 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?
- 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. Highrefractoriness, up to over 1790 DEG C 1600. Load softening start temperature to 1700 DEG C. Compressive strength at room temperature is 70 ~ 260MPa.. The thermal shock resistance of 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 alum clay as binder, forming and sintering made of fused mullite bricks with high alumina and bauxite, 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 than sintered mullite, thermal resistance Shock resistance than sintered products. The uniformity of content in alumina mainly depends on their high temperature properties and mullite phase and glass distribution. Mainly used in blast furnace, furnace top and bottom furnace, glass furnace regenerator, sintering kiln, petroleum cracking system dead lining.
- 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
- Mainly used for hot blast stove of blast furnace and furnace bottom and furnace, glass furnace regenerator, sintering kiln, petroleum cracking dead lining system.
- 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?
- Mullite refractory bricks can be used in construction, but their price is too high. We choose high alumina brick to meet the demand.
