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.

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.
- Q: How much is a thermal brick?
- 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 does refractory consist of?
- According to the chemical characteristics of refractory raw materials can be divided into acidic refractory materials, such as silica, zircon etc.; neutral refractory raw material, such as corundum, bauxite, mullite (acidic) (acidic), Ge (alkaline) iron and graphite; alkaline refractory materials, such as magnesite, dolomite, magnesium sand calcium sand.
- 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.
- Q: What refractory materials are adopted in each part of the blast furnace?
- The lower part of the shaft due to high temperature and dust by scouring and alkali metal vapor erosion, so the requirements for the slag resistance, alkali resistance and high temperature resistance, wear resistance of high quality clay brick, high alumina brick, carborundum brick or corundum brick. Belly temperature reaches 1400~1600, and slag, steam erosion, erosion and corrosion is strong, therefore, the silicon carbide reaction bonded silicon carbide brick.
- 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's the size of the fused zirconia corundum refractories for glass furnace? What are the main kilns? How much is the dosage?
- Fused zirconia corundum brick has a strong resistance to glass liquid corrosion!It is better to fuse the furnace with fused zirconia corundum bricks.Fused zirconia corundum brick, regardless of the size of the furnace, the use of small hundreds of kilograms can be used, depending on the design of the kiln!
- 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 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 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;
- Q: What can zirconium sponge do for those industries?
- Zirconium metal, also known as sponge zirconium, silver gray metal, the appearance of steel, shiny; melting point 1852 points, sub points, boiling point 4377 density 6.49. Zirconium is easy to absorb hydrogen, nitrogen and oxygen; zirconium has a strong affinity for oxygen; at 1000 DEG C oxygen dissolved in zirconium can make its volume increase significantly. Zirconium is relatively stable in the air; powder zirconium is easy to burn; fine zirconium wires can be ignited by matches; at high temperatures they can be combined directly with dissolved oxygen, nitrogen and hydrogen.
