As refractoriness
White Fused Alumina is the main starting material to produce high-grade unshaped and shaped refractoriness and is widely used in the field of iron-steel industry,ceramics,petrochemical industry etc. It is the ideal material to produce the unshaped refractoriness such as large ladle castables,medium and high grade BF trough castables,gunning material,pre-cast shapes and is the main material to produce alumina products such as corundum bricks, corundum and mullite-corundum sagger,refined porous plug bricks, monolithic lance composite nozzle, lining material for high temperature industrial furnaces,etc.
As abrasives
White Fused Alumina can be used as consolidation & coating abrasives, wet or dry sprayed grit, suitable for ultra-precise grinding and polishing in the crystal and electronic industry and can be used to produce high-grade refractoriness. It is suitable to machine high stiffness &high tensile strength materials such as chilled steel, alloyed steel, high-speed steel, high carbon steel, etc. In addition, it can be used as catalyst, insulator, precise foundry sand, etc.

- Q: What is the upper temperature limit for refractory materials?
- The key depends on what refractories you use
- Q: What is the main constituent of refractory brick?
- The main constituent of silica?brick is monox, etc. Refractory bricks have many kinds of texture. The main constituent of high alumina brick and clay brick is aluminium oxide. The main constituent of every texture is different. The main constituent of magnesia bricks and magnesia-chrome bricks is magnesium oxide.
- Q: How is grade of fire endurance divided?
- Fire resistance level is mainly decided according to the importance and function of the building. For example, very important buildings are set as the first level, and the less important is the second level, and so on.
- Q: Which are fireproofing external wall materials?
- 1. Acording to national standard GB8624-97, the combustion performance of construction materials are classified as: Grade-A: incombustible building material: Grade-A WW thermal insulation material which hardly burns. Grade-B1: nonflammable building material: nonflammable building material has good flame resistance. It is difficult to burn or spread in the air or at high temperature. Grade-B1: nonflammable building material: nonflammable building material has good flame resistance. It is easy to burn in the air or at high temperature, thus spreading the fire, such as wooden column, timber roof truss, timber beam and wooden stairway. Grade-B3: inflammable building material. Without fire resistance, inflammable building material is easy to burn and thus cause a fire. 2. According to fireproofing performance, external wall thermal insulation materials can be classified as: 1. Thermal insulation material with Grade-A combustion performance: WW inorganic thermal insulation material, rock wool, glass wool, foam glass, foamed ceramics and foam cement. 2. Thermal insulation material with Grade-B1 combustion performance: XPS panel after special treatment/ PU, phenolic aldehyde, gelatine powder polyphenyl granule after special treatment. 3. Thermal insulation material with Grade-B2 combustion performance: EPS, XPS, PU, PE, ETC.
- Q: Who knows about the criteria of fireproof and thermal insulation materials?
- Seven levels are divided according to "The classification of combustion performance of building materials and products", namely, A1, A2, B, C, D, E, F. It mainly refers to the combustion performance of materials. You can check on this standard for the specific dividing evidence. There are detail charts which mainly describe that whether there is drip or not, the ignition time, continuous burning time and so on.
- Q: What is the fire endurance of fireproof glass cotton?
- The highest temperature of fireproofing glass wool can be above 200 degrees, so it can be used for a long time,it's difficult to judge the special usage time, but its usually about 3 months and 8 hours every day.
- Q: What 's the highest temperature can magnesium plate glass resist ?
- Glass magnesium plate is non combustible plate having good fire-resisitance quality. Flame will never burn continuously on it. It does not catch on fire when temperature reach 800 ℃, and will not be lit up at 1200 ℃. The plate, having high-quality keel partition system, is rated as the highest non-combustible level A1 with fire resistance being above 3 hours. It absorbs a lot of heat when fire is burning, delaying rise of ambient temperature.
- Q: For refractory, why is it necessary to store the first mixing materials for some time under proper moisture and temperature?
- It is mainly to remove gas form chemical reactions in the pug, give full play to plasticity and binding properties of combined, and store unburned?brick whose cememting agent is phosphoric?acid or aluminium?phosphate for some time under proper moisture and temperature. For example, to avoid the formed bricks in the initial stage of drying and firing form cracking due to hydration of calcium oxide. Mixing materials is to store the first mixing materials for some time under proper moisture and temperature in order to improve the evenness and moldability of pud, such as making the distribution of combined clay and water more even. The length of storing chiefly depends on the process requirements and the characteristics of blanks. For the producing pug of high temperature kiln furnitures, the storing time is longer. The function of storing mxing materials varies with different natures of blanks. For honeycomb ceramics, it is to fully digest calcium oxide in blanks. For storing magnesia brick blanks containing much calcium oxide, it should be stored for some time in proper humidity and temperature.
- Q: Does anyone knows which company produces the better refractory materials?
- 1, Xinjiang Seekon new material limited liability company: Xishan Street No. 382,Saybagh District 2, Refractory Material Co., Ltd. In Xuyan, Benxi: Near the Sihu Road, Benxi City 3,Benxi Beitai new refractory material factory sales office address: Benxi city Sihu District Liu Toro No. 16
