Q: How much is a refractory brick?: This question is too general, refractory bricks according to the use of the environment and industry, there are a variety of materials, a variety of specifications, prices vary greatly.

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 is the blast furnace ceramic cup called by the refractory factory?: The peak of new materials in various coal, metallurgy, mines, ports, electricity, building materials and military industry, a lot of workpiece and affect production equipment due to wear, wear resistant materials although rarely cause disasters metal workpiece disaster, but the resulting economic loss is immeasurable.

Q: Expansion ratio of lightweight corundum refractory bricks: Light corundum refractory brick, because of its production methods and the introduction of different additives, there are certain differences in the content of Al2O3, just burn add general light corundum refractory brick and foam and gasification method cannot be made, the content of Al2O3 is generally not more than 99%, with alumina hollow ball manufacturing transfer are corundum brick with high content of Al2O3.

Q: What refractory materials are used in industrial furnaces?: Economically, it is necessary to do technical and economic analysis when selecting materials reasonably. Under the premise that the technical indexes agree with the working conditions of the furnace, the refractory materials with low quoted price should be used as much as possible, without high-grade finished products. To think about whether to make self (such as irrigation, refractory concrete) as far as possible to repair old.

Q: What are the main constituents of refractory bricks?: Corundum refractory brick and corundum brick is a kind of refractory brick with AL2O3 content not less than 90% and corundum as its main phase. It can be divided into sintered corundum bricks and fused corundum bricks.

Q: What kind of refractory material will be used in the glass kiln?: It has the best resistance to high temperature E glass corrosion, its erosion basically does not cause pollution to the glass liquid, so it has become the first choice of E glass unit refractory bricks.Dense chromium oxide is formed by isostatic pressing. Its density is very high. The main technical indexes include Cr2O3 content >94%, porosity <15%, volume density >4.24g/cm3, and erosion loss only 1/10 of compact zirconia brick. Used in the E glass furnace unit kiln, directly contact high temperature molten glass melt, wall, melting parts, high temperature parts, pool bottom, main channel, pool wall and pool bottom, transition channel, pool wall, 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: What are the refractory materials?: 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.

Q: What kind of rock is corundum produced?: If Ti4+ and Fe2+ containing a small amount of blue, a sapphire; containing six symmetrically distributed acicular rutile or other inclusions in some crystals, can produce six star awn, known as star ruby or sapphire stars, are precious stones. Corundum is vitreous luster with no cleavage, but cracks occur because of the presence of poly twin crystals that are often formed by the base or face of a face. Specific gravity 3.98. Of relatively low silicate igneous and metamorphic rocks and common in alluvial deposits. The U.S. state of North Carolina and Georgia, Russia's Ural mountains, South Africa as the main origin of the transvaal.
