      Alumina hollow spheres

            Alumina hollow spheres It is a kind of ultra-high temperature material energy saving thermal insulation material. It is made of alumina hollow spheres and alumina powder as the main raw material, combined with other binding agents and fired at 1750 degree high temperature.
      Alumina hollow sphere brick is a new type of high temperature insulation material. It is made from industrial aluminum oxide in electric furnace. With alumina hollow ball as the main body, it can be made into various shape products. The temperature of the product is higher than 1800 degrees, and the mechanical strength of the product is high. It is several times that of ordinary light weight products, and the volume density is only 1/2 of that of corundum products. Alumina hollow spheres are widely used in petrochemical industry gasifier, carbon black industrial reaction furnace, metallurgical industry induction furnace and other high temperature and ultra high temperature kilns, and have achieved very good energy saving effect.

          Meticulous, practice the core values; do not rush, carving the quality of Jinma products! Hello, customer friend, thank you for clicking on the official website of Gongyi Jinma burden Co., Ltd. The stability of demanding alumina hollow ball bricks reflects the ease of making in China. It has been the pursuit of Jinma burden for many years. If you want to know more about the actual application of alumina hollow brick products, please visit the details of the following alumina hollow brick product information or call the Jinma charging material [alumina hollow ball brick] technical advisory telephone: [13803857549 (Cai Jingli)] Learn more first-hand information!

            Alumina hollow spheres It is a kind of ultra-high temperature material energy saving thermal insulation material. It is made of alumina hollow spheres and alumina powder as the main raw material, combined with other binding agents and fired at 1750 degree high temperature.
      Alumina hollow sphere brick is a new type of high temperature insulation material. It is made from industrial aluminum oxide in electric furnace. With alumina hollow ball as the main body, it can be made into various shape products. The temperature of the product is higher than 1800 degrees, and the mechanical strength of the product is high. It is several times that of ordinary light weight products, and the volume density is only 1/2 of that of corundum products. Alumina hollow spheres Widely used in petrochemical industry gasifier, carbon black industrial reaction furnace, metallurgical industry induction furnace and other high temperature and ultra high temperature furnace, and has achieved very good energy saving effect.
      Alumina hollow spheres and their products are excellent lightweight refractory materials with high temperature and energy saving. They are very stable in various atmospheres. It is especially applied to high temperature kiln at 1800 C. Hollow spheres can be used for high temperature, ultra high temperature insulation fillers, high temperature refractory concrete lightweight aggregate, high temperature castables, etc. Hollow brick can be used in high temperature energy saving (>30%) down flame kiln, shuttle kiln, molybdenum wire furnace, tungsten bar furnace, induction furnace, nitriding furnace and so on. For reducing furnace weight, improving structure, saving materials and saving energy, obvious results will be achieved.
      Aluminum oxide powder is made of reassuring industrial alumina as raw material. It adopts new high temperature down flame kiln and scientific calcination process. It has manual selection, clear classification, less impurity, high conversion rate, stable shrinkage and good consistency.

      For reducing furnace weight, improving structure, saving materials and saving energy, obvious results will be achieved.
      1, high usage temperature:
      It can reach more than 1750 degrees and has good thermal stability. The reburning line has a lower rate of change and longer usage.
      2, optimize the structure and reduce the weight of the furnace.
      Now the high temperature resistant materials are all heavy bricks with a bulk density of 2.6-3.0g/cm, while the alumina hollow brick is only 1.1~1.5g/cm and the same cubic meter volume. The alumina hollow ball bricks can reduce the weight of 1.1-1.9 tons.
      3, save materials:
      To achieve the same service temperature, such as the use of heavy bricks, the price is comparable to that of alumina hollow brick, and considerable insulation materials are needed. If the alumina hollow ball bricks are used, the use of heavy bricks of 1.1-1.9 tons can be saved per cubic meter, and 80% of the fireproof and thermal insulation materials can be saved.
      4, save energy:
      Alumina hollow spheres have obvious thermal insulation characteristics and low thermal conductivity. They can play a good thermal insulation effect, reduce heat emission and improve thermal efficiency, thereby saving energy. The energy saving effect can reach more than 30%.
