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 are the varieties of polycrystalline mullite?
PMF (polycrystalline mullite fiber) is an international super light resistant high temperature heat insulation material of the latest, it consists of mullite micro crystal which integrates crystal and fiber materials properties in one, has an excellent thermal stability, temperature 1500, melting point 1840, the thermal conductivity of refractory brick is a traditional 1/6, bulk only the 1/25 is the ideal material for high temperature furnace energy saving.
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: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:The introduction of mullite brick
High alumina refractory with crystalline mullite (3Al2O3, 2SiO2) as the main crystal phase.
Q:Mullite bricks on 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: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: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 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.
