Solar photovoltaic industry components

 

Monocrystalline silicon is a large number of raw materials required by semiconductor and photovoltaic industries. Monocrystalline silicon materials are prepared and produced by the special equipment "monocrystalline silicon crystal growth furnace". Improving the production capacity of monocrystalline silicon and reducing the production cost of monocrystalline silicon are the technical issues that crystal manufacturers have been solving through equipment improvement and optimization for a long time. Increasing crystal casting speed is one of the important means to improve production efficiency and control production cost. In recent years, domestic and foreign crystal manufacturers have added a layer of molybdenum draft tube (also known as guide cylinder molybdenum bushing) in the graphite guide cylinder. The application of this technology and product not only can isolate the direct radiation between graphite and crystal rod, but also effectively control the temperature of crystal rod, and further improve the speed of crystal drawing. At present, the selection of all kinds of furnace type molybdenum draft tubes for monocrystalline silicon production at home and abroad is to use "flat molybdenum plate" to make draft tube. At present, the flat type guide tube and wave linear guide plate selected in the crystal drawing market can only solve the problem of preventing light and heat radiation. However, after radiation, the high temperature area in the guide tube is concentrated on the single crystal rod, which leads to the problem that the temperature center of the single crystal rod is too high, which seriously affects the speed of crystal drawing, and the service life is also low, which leads to the high cost of monocrystalline silicon manufacturing.

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.
