General Information of Corundum Bricks
CMAX corundum bricks use compact electro-smelted corundum and alumina powder as main raw materials, shaped under high pressure after machine-blending and fired at high temperature.
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 are conducted by workers and then each piece will be sorted and examined by quality supervis
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 us U.S., UAE, Saudi Arabia, Iran, and Russia, etc.
- Q: What is the main component of corundum?
- The name of corundum originates from India and is the name of mineralogy. There are three main variants of corundum Al2O3, which are alpha -Al2O3, beta -Al2O3 and gamma -Al2O3 respectively. Corundum is second only to diamond.
- 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'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 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 is the difference between corundum and high alumina?
- The main component of high purity 99 corundum brick is corundum sand,90 corundum brick is mainly composed of corundum sand and a small amount of Suzhou soil, mullite.
- Q: High temperature refractory material?
- Acid refractory with silicon oxide (SiO2) as the main ingredient, commonly used are silica brick and clay brick is siliceous. Products containing more than 93% SiO2, the use of raw materials with silica, silica and other waste brick. Acid slag erosion ability is strong, but vulnerable to the erosion of basic slag, its softening temperature is very high that is close to the refractory, the volume does not shrink after repeated burning, or even a slight swelling, but the thermal shock stability. Silica is mainly used for thermal equipment of coke oven, glass furnace, furnace and other acidic silica brick, according to the physicochemical indexes and SiO2 content can be divided into several levels, mainly brick for glass furnaces and used for coke oven two kinds of brick clay brick. With refractory clay or bauxite clinker as main raw material, containing 30% to 46% of alumina, refractory degrees 1580 to 1770 DEG C, weak acid refractory material, heat shock resistance, resistance to acid slag, wide application Pan, clay brick with refractory clay as main raw material is called ordinary clay brick, made with bauxite clinker as main raw material, the porosity in the clay brick below 17% is called low porosity clay brick. Two kinds of clay brick and according to the physicochemical indexes which were divided into several grades, the price difference between ordinary clay brick and low porosity clay brick greatly.
- 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: 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 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: 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.
