Q:Ask for help about the phase of refractory material
Secondary crystalline phase. The second phase and second phase or second phase, and the main crystal phase and is in high temperature liquid phase coexistence in refractory material, the number and influence on high temperature properties of materials is the main crystal phase is small second phases. As to the main crystalline phase of periclase magnesia chrome brick, magnesia brick, magnesia brick and magnesia calcium brick respectively containing Cr spinel, spinel, forsterite and calcium silicate two are secondary phase. There are structure of refractory refractory material in the crystal phase, especially the direct combination of high melting point and so on, the resistance to high temperature also tend to benefit. Compared with the ordinary brick, the second phase of the refractory products, make the products refractoriness under load are improved. Many according to mineral composition of refractory material named, such as mullite corundum brick, corundum mullite brick, is its main crystal phase and the second phase composite named. The former is mainly crystal phase, the latter is sub crystalline phase.
Q:What is the hardness of corundum refractory bricks?
Al2O3 containing more than 90% greater than the refractory brick called corundum refractory brick, also known as pure alumina refractory products. Corundum has a high hardness (9 Mohs hardness) and a high melting point. These are closely related to the firmness of the Al - 0 bond in the structure. Therefore, a-Al2O3 is the main phase of making high temperature refractory bricks and high temperature electrical insulating materials.
Q:What kind of refractory material will be used in the glass kiln
The content of ZrO2 in the brick is about 66%, and the bulk density is 3.7g/cm3, which has better thermal stability and anti stripping property. The use of erosion serious investment outlet area and after the parapet wall in the powder melting furnace, observation hole brick and pathway of flame space and roof parapet wall brick, brick burner. But there are also AZS burner brick with mullite brick for brick kiln and transition two side clearance brick etc..
Q:High temperature refractory material
Many kinds of refractory materials, usually by refractoriness level is divided into ordinary refractory materials (1580 to 1770 DEG C), advanced refractories (1770 to 2000 DEG C) and special refractories (more than 2000 DEG C); according to the chemical characteristics into acid refractory material, refractory materials and basic refractory materials. In addition, the refractory material used for special occasions.
Q:Can the PE sintering plate dust collector be suitable for dust removal in the coking plant?
Do not know where the coking plant do dust treatment, processing conditions are different, the dust collector is not the same
Q:What is the price of concrete self insulation bricks?
If you really want to buy thermal insulation brick, do not simply look at the price, but also to consider the quality of the product. (a piece of brick in the market basically in 6 yuan, if there is a floating price if it is because of the size of the insulation brick or distance, but floating slightly.)
Q:What are the advantages of refractories?
Special refractories are new inorganic non-metallic materials developed on the basis of traditional ceramics and refractory materials. For example, AZS brick, corundum brick, magnesia chrome brick, silicon carbide, silicon nitride bonded silicon carbide, nitrides, silicides, sulfide, boride, carbide and other non oxide refractory materials; calcium oxide, chromium oxide, alumina, Magnesium Oxide, beryllium and other refractory materials. Often used insulation refractories are diatomite products, asbestos products, insulation panels and so on
Q:What's the size of the fused zirconia corundum refractories for glass furnace? What are the main kilns? How much is the dosage?
The fused zirconia corundum brick is made up of 30% ~ 41% zirconia two in the alumina burden. The main mineral compositions are corundum, zircon and glass phase. The main varieties are fused (or cast) zirconium corundum brick (also known as AZS casting brick) and sintered zirconia corundum brick. Generally speaking, zircon corundum brick means sintered zirconia corundum brick. It is made from alpha -Al2O3, partially stabilized zirconia and zircon corundum clinker, which is prepared by proportioning and molding at 1700~1750 DEG C and then sintered at two. The sintered zirconium corundum brick has a strong resistance to molten glass, and its thermal shock resistance is stronger than that of fused zirconia corundum brick. It is mainly used as lining of glass furnace and induction furnace, as well as steel rolling furnace, slide rail, etc..
Q:What is the difference between T3 refractory bricks and high alumina refractory bricks?
The T3 in T3 refractory bricks refers to the model indicating that the refractory brick model is T-3, and that the corresponding T-3 model is 230*114*65 (mm)
Q:Application of electric high temperature regulating valve?
Many kinds of refractory materials, usually by refractoriness level is divided into ordinary refractory materials (1580 to 1770 DEG C), advanced refractories (1770 to 2000 DEG C) and special refractories (more than 2000 DEG C); according to the chemical characteristics into acid refractory material, refractory materials and basic refractory materials. In addition, there are refractories for special occasions.
