Description:
SIMAS65 is a kind of sintered spinel made of high purity alumina powder and high quality active
magnesia, sintered at super-high temperature. It has low creep rate, small thermal expansion
coefficient, the strong ability of anti-chemical corrosion.
Applications:
SIMAS65 is used for making high quality castables for ladle and for con-casting slide plates, SIMAS65 is also widely used for making blast furnace hearth, stove and ceramic kiln.

Pictures:
- Q: Where is the production of refractory manganese alloy manufacturers? Manganese is recommended between 63 and 70!
- The cut is relatively transparent if you jam, we have also used silicon manganese alloy
- Q: How about the prospect of refractory material?
- Due to the rise of raw material, the prospect is not good with inflation, lower prices and decreased profits. The product requirements have been enhanced and there is vicious competition. Therefore, it is really bad.
- Q: How is grade of fire endurance divided?
- You can search the answer on the Internet, thank you!
- Q: what kind of fireproof materials is used for high rise buildings?
- Recommended thickness of 1mm or more # 304 stainless steel, refractory, corrosion-resistant, easy to clean. closed balcony of high rise buildings use thickened manganese, aluminum profiles. You can also use plastic steel window, solid wooden windows. Mg-Mn alloys have excellent weldability and corrosion resistance, unstressed corrosion tendency. Mechanical properties are not good enough, the ultimate strength of 210 ~ 280MPa.
- Q: Can I use ordinary cement with the addition of sand, clay, and salt as refractory material to paste the stove?
- Add some hair and slags, or it will crack before calcination.
- Q: who knows the fire resistant level of fireproof gypsum board ?
- Gypsum board is flame retardant materials, combustion performance rating B1, but when mounted on a steel joist, it can be seen as rating A(non-combustible material) . So it is fine to use as a ceiling. As for the Dragon brand, rock wool can be filled in the mddle according to its design requirements, using different series of gypsum board, steel stud. the walls may have fire resistance and sound insulation property of various degrees. You can randomly choose several samples to run some tests at the quality inspection insititute and the quality of these samples are subject to the testing results.
- Q: Fire resistance and evaluation of refractory for casting
- The refractory degree of refractory material at high temperature is called refractoriness. Refractory products all contain substances from fusible sintering action, the melt crystal as unlike at a fixed temperature, but the temperature in a wide range. At a lower temperature, a small amount of melt is formed, and as the temperature increases, the amount of the melt increases, and the product gradually softens. Refractoriness and melting point (crystal) are different concepts.
- Q: Urgent question: could you tell me that the export of refractory materials to Vietnam is to be packed in wooden cases and smoked?
- Why is the apple screen so small?
- Q: What is refractory cement?
- Ordinary portland cement is common cement with relatively high early strength, while refractory cement is low in this regard. Refractory cement is a characteristic cement which can only be used in special projects, not suitable for general engineering. And in the winter, it is not suitable for construction use.
- Q: How many levels are there in the classification of PP fireproof materials?
- PP fireproof materials level V-0: After two 10-second fame tests on the sample, the flame extinguishes within 30 seconds. Inflamer can not drop. V-1: After two 10-second flame tests on the sample, the flame extinguishes within 60 seconds. Inflamer can not drop. V-2: After two 10-second flame tests on the sample, the flame extinguishes within 60 seconds. Inflamer can drop.
