With the rapid development of the world industry, graphite has been regarded as one of the important industrial mineral raw materials at home and abroad. At present, the graphite dies are widely used in the following aspects: - Graphite dies used for non-ferrous metal continuous casting and semi continuous casting In recent years, the advanced production methods of directly continuous (or semi continuous) producing rods or tubes from the state of molten metal were promoted at home and abroad. We have begun to use this method in domestic copper, copper alloy, aluminum, aluminum alloy and other aspects . Artificial graphite is considered as the most suitable material for continuous casting or semi continuous casting of nonferrous metals. Production practice has…
Carbon carbon composite material is carbon fiber reinforced carbon matrix composites. Carbon carbon composite material is derived from an unexpected discovery. In 1958, the United States VOUGHT CHANCE Laboratory,Carbon matrix was obtained from the carbon / phenolic experiment because of the failure of the operation. As a result, a new member of the composite family has been added. The main preparation procedure of carbon carbon composite material is : preform molding, densifying and graphitization. Densification technology is the key technology of carbon carbon composite material. The densification methods of carbon carbon composite material are mainly divided into two categories: vapor deposition and liquid phase impregnation, liquid phase impregnation is divided into resin impregnation and asphalt impregnation. The typical process of…
Graphite material has the advantages of high machining accuracy and good surface effect, especially in precision, complex, thin wall, high hardness material mold cavity processing has a greater advantage. brief introduction Graphite material has the advantages of high machining accuracy and good surface effect, especially in precision, complex, thin wall, Gao Ying material mold cavity processing has a greater advantage. Compared with copper, graphite material has the advantages of less consumption, high discharge speed, light weight, small thermal expansion coefficient, etc. Therefore, it has become the mainstream of the discharge machining materials. advantage One, fast speed; Graphite discharge faster than copper 2-3 times, the material is not easy to deformation, in the processing of thin reinforced electrode have obvious advantages,…
