Special graphite covering a wide range of industry have different understanding and classification of carbon products Chinese industry, electrical carbon products of natural graphite products industry and metallurgy, metallurgy is used to explain the classification of carbon products, special graphite mainly refers to high strength, high density, high purity graphite products (referred to as the three high graphite). From the three high graphite material structure can be divided into coarse grain structure, fine grain structure and fine grain structure of three kinds of molding methods are distinguished from molding special graphite, extrusion molding and special graphite isostatic pressing special graphite three categories, in addition, vibration molding can also be used in the production of special graphite. High quality special graphite,…
1. It is made of high strength pressed high purity graphite material. It has high strength, strong oxidation resistance and long service life. 2, the use of machining centers and CNC machine tools fine machining, high accuracy, good concentricity, jitter in the use of small, effectively prevent high-speed fracture, reduce accidents. 3. The graphite turntable has several wheels. When rotating, it can form gas / liquid flow, increase the contact area and contact time between the bubbles and the aluminum alloy liquid, and improve the degassing effect. The friction between the wheel and the aluminum alloy is relatively small. Thus, the degassing rate is above 50%, the smelting time is shortened, and the production cost is reduced. 4, the graphite…
The working principle of graphite copper sleeve: general solid lubricant accounted for friction surface area 20-30%, lubrication principle of graphite self-lubricating bearing copper sleeve is in sliding friction process of shaft and bearing, graphite particles as part of transfer to the friction surface of the shaft and the bearing on the formation of a layer of relatively stable solid lubricating diaphragm. To prevent the direct adhesion of shaft and bearing wear. This combination of rationality combines the advantages and disadvantages of the metal alloy and the non-metallic antifriction material, and is complementary to each other, namely, the high carrying capacity of the metal, and the lubricity of the antifriction material. So it is especially suitable for the environment such as…
