Corundum Abrasive Manufacturers Share Knowledge Of Corundum

  • Today, Corundum Abrasivemanufacturers share the causes of corundum:

    1. The high temperature and high pressure conditions formed in the mantle are sprayed out of the earth's surface with the magma.

    2, formed in contact metamorphism

    Due to its excellent high temperature properties and mechanical strength, corundum is widely used in many industrial fields such as metallurgy, machinery, chemical, electronics, aviation and national defense. Its main uses are as follows.

    1, due to high temperature, corrosion resistance, high strength and other properties, it is used as a steel sliding nozzle, smelting rare metals, special alloys, high-purity metals, glass drawing, making laser glass enamel and utensils; various high-temperature furnaces Such as refractory materials, ceramics, linings (walls and tubes) of iron-making blast furnaces; physicochemical vessels, spark plugs, heat-resistant anti-oxidation coatings.

    2, due to the characteristics of high hardness, good wear resistance and high strength, in the chemical system, used as various reaction vessels and pipes, parts of chemical pumps; as mechanical parts, various molds, such as wire drawing die, extrusion Pencil core mold mouth, etc.; for tools, abrasive abrasives, bulletproof materials, human joints, sealing rings and so on.

    3. Because of the high temperature insulation, it is used as a ferrule tube and protection tube for thermocouples. The insulation used in the atomic reactor is still excellent, and the loss is not large, and the dielectric constant is not large. It is widely used in the electronics industry. It is used for solid integrated electric furnace substrate tube holder, outer casing, porcelain frame, micro-thin window, missile radar antenna protection cover, etc.
