Chromium Fused Alumina

Author:Jinlin corundumTo update: 2016-09-08

With respect to the type of abrasive products, recognized by everyone is also brown fused alumina, white fused alumina, black fused alumina, silicon carbide and the like product, but for chromium fused alumina, a lot of people are not very familiar with, perhaps only heard, but and no in-depth understanding of the production process through the chromium fused alumina, performance, and other effects.

Jinlin chromium fused alumina look purple or pink, the smelting process with the same Jinlin white fused alumina, alumina powder is the main raw material, but a certain amount of chromium oxide in the smelting process, high temperature smelting made, but Jinlin chromium fused alumina in the production process due to the introduction of Cr3 + to improve the toughness of the abrasive, so Jinlin chromium fused alumina hardness and white fused aluminaare similar, but toughness higher than white fused alumina, and hence more ductile material is used for processing, the processing efficiency higher than white fused alumina and surface finish of better.

Jinlin chromium fused alumina purposes:

  1. Referring Jinlin chromium fused alumina production process, etc., we can know Jinlin chromium fused alumina with high hardness, high toughness, high purity, grinding power, high efficiency, high temperature, and other characteristics, these characteristics Jinlin chromium fused alumina. It can be widely used in grinding wheels, cutting discs, sandpaper, sandblasting, refractory materials and other industries.
  2. Jinlin chromium fused aluminacan be said is the best blasting material that is suitable for metal, glass, zinc alloy, aluminum, stainless steel, sandblasted. As best wiping material Jinlin chromium fused alumina, especially in terms of spraying thin-walled workpieces most significant effect, it makes the work does not change color, high finish machining. As the sandblasting, the main models it uses:8,10,12,14,16,20,24,30,36,46,54,60,80,100,120,150,180,220.
  3. Jinlin chromium fused alumina silicon wafers, precision instruments, polished glass, glassware, ceramics, stone, leather, plastic, metal parts and other products can improve the finish. As a finish to improve aspects of the product is that its main models: 240,280,320,360,400,500,600,800,1000,1200,1500,2000,2500,3000,4000,6000,8000,10000,12000 .
  4. Abrasive grinding Jinlin chromium fused aluminamade of sharp, low heat generation rate, grinding ratio, and less in the course of the buildup; sintering abrasive fused alumina made of chrome with Jinlin having after firing dark blue color, can not afford to mesh cracks, no rust characteristics. In the abrasive side, Jinlin chromium fused alumina used main types: 30,36,46,54,60,80,100,120,150,180,220,240,280,320,360,400,500,600, 800,1000,1200,1500,2000.
  5. Jinlin chromium fused alumina abrasive tools made of durable good, grinding finish. Suitable for machine tool spindles, instrument parts, threaded parts and other precision grinding mill model.
  6. Jinlin chromium fused alumina suitable for the manufacture of ceramics, resins and high abrasive grinding, polishing.
  7. Jinlin as chromium fused alumina refractory with 0-1,1-3,3-5,5-8,3-8,1-2,3-6, 8-12mm etc. -100, – 180, -200, -220, -320, -325 mesh, etc. used in the steel, foundry, petrochemicals, air brick, ladle lining, casting materials, ceramics and other fields, is an excellent fire-resistant materials. Refractoriness high hardness, good thermal shock resistance, corrosion resistance and wear resistance, stable performance.

The physical properties of chromium fused alumina abrasives:

Jinlin Fused Alumina Refractories Company remind the majority of users, chromium fused alumina in storage, should be stored in a cool dry place to prevent rupture of the inner and outer bag to prevent moisture absorption and other substances in the air, affect the results. With no toxic gases or volatile substances mix, stored away from sources of pollution. Jinlin Fused Alumina Refractories Company is a professional manufacturer of abrasives, the company pursues a “people-oriented, technology-plant” management philosophy and the “sake of users really, honest customer service” business purpose. Welcome friends to visit, guidance and business negotiation.
