Application of tungsten molybdenum sapphire long crystal furnace

  

  The composition of sapphire is alumina, and it is blue because of the trace elements of titanium (Ti4 +) or iron (Fe2 +). It belongs to the trigonal system. The crystal morphology is usually cylindrical, short columnar and plate-shaped, and the geometry is mostly granular or dense block. Transparent to translucent, glass luster. The refractive index is 1.76-1.77, the birefringence is 0.008, and the dichroism is strong. Heteroplasm. Sometimes it has special optical effect starlight effect. The hardness is 9 and the density is 3.95-4.1 g / cm3.

  Sapphire is a single crystal of alumina, which has excellent mechanical, optical, chemical and radiation resistance properties, so it is widely used in optical components and mechanical manufacturing industries. In the production of blue and white LED, the substrate material used is mainly sapphire. As blue and white LED has the advantages of long service life, low power consumption and high luminous efficiency, LED has become the mainstream of lighting lamps in the future, so the market demand of sapphire as the base material of blue and white LED is also greatly increased.

Main product advantages:

    -We are one of the earliest domestic enterprises engaged in the research and production of tungsten and molybdenum materials.
    -We have rich experience in the production of tungsten crucible. We can produce various kinds of tungsten crucibles of different kilogram grades. We can customize them according to the requirements of customers and fully meet your requirements.
    -2 g / cm3.
    -The roughness of the inner surface of the crucible can reach Ra0.4. With this finish, the crystal can be easily taken out of the crucible without any damage, and the crystal surface grown out is particularly smooth.
    -No need to bake the oven. In general, tungsten crucible should be dried before long crystal. The tungsten crucible of our company can grow qualified single crystal in the first furnace and reduce the production cost.
    -Good creep resistance ensures the consistency of product size, and the overall size consistency is good after several heats of use.
    -With sufficient capacity and stable performance. Now it is in mass production with a capacity of about 400 pieces / month.

Xi'an gemei metal materials Co. Ltd. production began to control from raw materials, continuous selection of quality raw materials, product stability and consistency is very prominent. For different grades of raw materials, marking, marking the lot number. And for each batch of raw materials sampling inspection, inspection and filing. Ensure that the finished product has traceability, continuous improvement of product quality. Xi'an gemei metal materials Co. Ltd. production milling process control is very accurate, with several large mixing machine and vibration platform, ensure milling and mixing process of materials can be fully stirred, to ensure the consistency of the internal organization of product. Xi'an gemei metal materials Co. Ltd. production began to control from raw materials, continuous selection of quality raw materials, product stability and consistency is very prominent. In powder metallurgy, the metal powder is heated by the static pressure to form a blank, which is lower than the melting point of the main component, so that the connection between the particles and the method of improving the properties of the product is called sintering. Powder after forming, dense bodies obtained by sintering is a polycrystalline material, sintering process directly affects the microstructure of grain size, pore size and grain shape and distribution, is the core technology of powder metallurgy. In powder metallurgy, the metal powder is heated by the static pressure to form a blank, which is lower than the melting point of the main component, so that the connection between the particles and the method of improving the properties of the product is called sintering. Powder after forming, dense bodies obtained by sintering is a polycrystalline material, sintering process directly affects the microstructure of grain size, pore size and grain shape and distribution, is the core technology of powder metallurgy. The material can obtain a higher density and superior mechanical properties, and play a role in strengthening the surface. Accurately grasp the processing rate of tungsten and molybdenum materials, forging and forging temperature, is an important factor in gemei tungsten molybdenum material having excellent performance. Use of metal billets forging machinery pressure, the processing method of plastic deformation in order to obtain a certain mechanical properties, shape and size of forging. Forging (forging and stamping) the two part of. By forging can eliminate the casting defects such as loose metal produced in the smelting process, the microstructure is optimized, and the preservation of the integrity of the metal flow, the mechanical properties of forgings generally better than the same materials of casting. In this process, the metal material is under the pressure of the rotating roller, which has a continuous plastic deformation, and the shape and performance of the section are obtained. Gemei has advanced tungsten and molybdenum cold and hot rolling technology and equipment from tungsten and molybdenum metal billet to the production of tungsten and molybdenum foils, gemei for you to ensure the production process is more advanced and more superior performance of metal. The heat treatment can eliminate the stress in the internal structure of the metal, make the internal structure even and balanced, and give full play to the properties of the material. In this way, cracks caused by incomplete stress relief can be avoided in the subsequent machining process. Gemei has such as cars, milling, planing, milling and other mechanical processing equipment and technology, made of tungsten and molybdenum materials to meet the requirements of various use requirements and surface. Lathe machining is a part of machining. The lathe is mainly used for machining of rotary workpiece. Can also be used in the lathe drill, drill reamer taps Banya and knurling tools for the corresponding processing. Xi'an gemei metal materials Co. Ltd. products began to quality control from raw materials, and each process of quality inspection and sampling, ensure each process products quality inspection process control, finished product, material for the apparent size and internal tissues were detected in the products one by one, the stability and consistency is very prominent.
