Product Description:

What is Corundum Brick?

l  Corundum Bricks are high alumina refractory bricks are made for extreme demands. The alumina content in Corundum Bricks can be traced to the use of synthetic corundum of high purity, such as white fused alumina or tabular alumina. Additional ingredients are special refractory clays, reactive alumina and very pure modifications of silica.

l  Corundum Bricks are fired at high temperatures to form a matrix with mullite, mullite-corundum or corundum that has excellent volume stability.

l  The service temperature for Corundum Bricks goes up to 1800°C.

 

What are the applications of Corundum Brick?

Corundum Bricks can be used nearly all fields of industrial application where extreme high temperature and increased resistance against aggressive slags and atmospheres. Such properties or features of Corundum Bricks are necessary especially in the chemical industry and for the production of carbon black. The addition of chromium oxide, zirconium oxide and phosphates lends the bricks excellent structural flexibility, which is required for ash melting furnaces and gas reactors in incinerators.

FAQ

Q1: How do you control the products quality?

A1: With strict quality control system throughout the materials selection and production process, our refractory and ceramic fiber products quality is effectively controlled to meet customer requirements.

From the raw materials selecting, our quality control begin. The quality certificates of raw materials are required and each batch will be tested before using. During production, the quality control is conducted by workers and then each piece will be sorted and examined by quality supervisor.

 

Q2: What`s the lead time for my order?

A2: It depends on customers’ requirements and our production schedule. And usually we need 30-60 days for refractory bricks, 10-25 days for unshaped refractory materials and 10-20 days for ceramic fiber blankets.

 

Q3: Can you offer Door-to-Door delivery?

A3: Yes, but only for some countries such as U.S., UAE, Saudi Arabia, Iran, and Russia, etc.

 

Q4: What is the minimum quantity?

A4: There is no minimum order quantity. Depending on the item and processing, there may be a minimum production required, however we can offer a quotation based only on the quantity you need.

 

Q5: Can you give me a brief introduction of the application of your products?

A5: CNBM (China National Building Material) core refractory business comprises the production, sale and installation of high-grade refractory products, the development and implementation of customized system solutions as well as rendering outstanding services for the key industries in Glass, Iron& Steel, Petrochemical, Cement, Ceramic and Nonferrous Metals.

Q:Zirconium corundum 25 content and 40 content, how to distinguish in appearance?
Fused zirconia corundum brick is pure alumina and zirconia containing silica 65%, about 34% of the zircon sand in electric furnace melting after internalization into moulds cooling and the formation of the white solid, the petrographic structure by zirconium corundum and plagioclase eutectoid and glass phases, from the phase is eutectoid zirconium corundum and plagioclase phase, glass phase filling between their crystallization.
Q:What problems should we pay attention to in the use of fused zirconia corundum brick (fused zirconia corundum brick) in glass furnace?
Cast brick and clay brick masonry contact, eutectic phenomenon will occur at 1300 degrees Celsius, the selection of refractory materials, should avoid eutectic phenomenon serious two kinds of refractory materials such as brick masonry contact, in the following cast brick, the most vulnerable to erosion fused zirconium corundum brick.
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:Which is good, glazed brick and whole cast glazed brick?
Vitreous tile is all ceramic tile, the material is hard, strong wear resistance, smooth finish is very good, in general, looks very bright. Microcrystalline brick, corundum brick Market said, they really mean bohuazhuan. Because of its low water absorption and high strength and hardness, glazed tile has been widely used. Many hotels, shopping malls and office space are widely used glass tile.
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: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:What equipment is used for producing diamond blanks? How much is the investment?
You'll have to invest about about one million if you want an electric furnace. A power distribution room is easiest to approach one hundred thousand. Electric furnaces, power distribution cabinets and transformers must be around one hundred and ten thousand.
Q:Which is faster for heat transfer between corundum bricks and high alumina bricks
There must be a difference. They vary in color from the amount of aluminum, the weight, the temperature, and the color.
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:What kind of rock is corundum produced?
Aluminum oxide (Al2O3) mineral. Due to Mohs hardness of up to 9, mainly used as high-grade abrasives. The crystal belongs to the three party system, a dolioform six square column, some are needle or plate. Aggregates are massive or columnar. Usually white, gray, yellow and other colors. If a small amount of Cr3+ is red, a ruby is called;
