Product Description:

The high purity corundum brick produced by us made from the imported tabular corundum, high purity fused corundum as main raw materials, the application of superfine powder with advanced technology, after mixing, molding, drying, in shuttle kiln high temperature burn becomes.

High purity corundum brick with high refractoriness, good thermal shock resistance and high temperature strength, strong corrosion resistance, slag resistance and small expansion coefficient, low creep and spalling resistance, suitable for all kinds of atmosphere under the condition of high temperature furnace use;High purity corundum brick is widely applied in zirconia ceramics, fluorescent material, electronic ceramics, magnetic materials, ceramic powders of high temperature sintering and petrochemical industries gasifier, 2 of ammonia conversion furnace, carbon black reactor, glass industrial furnace equipment, etc.Appearance size, physical and chemical index of the products, service life have reached or exceed the level of similar products at home and abroad.

Q:What are the refractory materials?
Basic refractories in Magnesium Oxide and calcium oxide as the main ingredient, commonly used is brick. Magnesium Oxide 80% to more than 85% containing magnesia brick, has good resistance to alkaline slag and slag, refractory clay brick and brick high ratio. Mainly used in open hearth furnace, oxygen converter, electric furnace, non-ferrous metal smelting equipment and high temperature equipment.
Q:What can zirconium sponge do for those industries?
Uses: aerospace, military, nuclear reactions, atomic energy, and metal superhard materials, the manufacture of bulletproof alloy steel, can also be used in the reactor uranium fuel coating alloy; zirconium at high temperatures easy to launch electronicProduct characteristics: zirconium metal has very strong corrosion resistance, ultra high hardness and strength
Q:What's the jade stove for?
Corundum furnace for corundum smelting furnace, usually electric arc furnace for smelting dense corundum, corundum, white corundum, zirconia corundum, magnesia, magnesium aluminum spinel and fused refractory materials, professional design, Xi'an Xinda furnace engineering limited liability company manufacturing corundum furnace.
Q:What are the advantages of refractories?
Acid refractory material usually refers to refractories with SiO2 content greater than 93%. Its main characteristic is that it can resist acid slag corrosion at high temperature, but it is easy to react with alkaline slag.
Q:How much is a thermal brick?
Insulation brick prices also have a great relationship with the material and workmanship, such as clay brick price is much lower than high alumina brick, mullite and corundum brick prices will be higher.
Q:Can the fire clay be reused?
Refractory soil cannot be reused.Clay refractory soil 1, characteristics and uses: Clay refractory brick is a weak acid refractory material, its thermal stability is good, suitable for hot air furnace, all kinds of boiler lining, and flue, smoke room, etc.. 2, product specifications form: standard shape, general, special-shaped and special-shaped brick. Physical and chemical properties of fireclay bricks.
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: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 material is used in an iron smelting furnace?
In fact, refractory refractory ah is special ceramic frequently used 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.
Q:Expansion ratio of lightweight corundum refractory bricks
Now with the production of lightweight foam corundum brick, basically still meters with molding casting, moulding after together with die in the drying room drying in 60~70 C 4 days of release, then the appropriate drying, finally after 1300 and 1550 C firing, the total burning time: 50~60h. Light corundum brick after firing is usually not the size and shape of accurate, so that products after the kiln to mechanical or manual cutting, can be made into a density of 0.8 - 1.3g/cm3, 4MPa compressive strength and porosity, the thermal conductivity of 70%~80% 0.17W/ (M - K), light-weight corundum brick use temperature of 1500~1700 DEG C.
