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.

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

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:Aluminum content 38, silicon content 55 What refractory bricks?: The mineral composition of the high alumina brick is determined by the bauxite used. The mineral composition of the clinker is usually mullite, corundum and glass. The theoretical composition of mullite is Al2O371.8%, SiO2 28.2%, and its melting decomposition temperature is 1840 DEG C. With acicular crystal, network cross structure, high temperature state showed better strength. Corundum in the form of alpha -Al2O3, melting point of 2050 degrees, hardness of Mohs 9, showing a granular and columnar crystal, has good chemical stability, acid, alkaline slag have a certain resistance. Based on the composition of mullite minerals, the phase composition of high alumina brick can be judged according to the content of Al2O3.

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: If there is no mark, ask the laboratory of the production factory to analyze any chemical or physical items. Or, check the national standard, the national standard has the basic requirements of the physical indicators

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?: 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: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.
