1: the increasing complexity of the mold geometry and the diversification of product applications lead to more and more accurate discharge accuracy of the machine. Graphite electrode has the advantages of easy processing, high removal rate of discharge machining, small graphite loss, and therefore, some of the group of spark machine customers to give up the copper electrode and graphite electrode. Also some special shape electrode cannot be made of copper, but graphite is easy molding and copper electrode is heavy, not suitable for the processing of large electrode, these factors caused partial group base spark machine customers by graphite electrode. 2: graphite electrode is easy to process, and the processing speed is much faster than the copper electrode. For…
As the graphite block materials with thermal expansion coefficient is low, good resistance to thermal shock, neutron activation properties such as excellent performance, nuclear reactor (especially in high temperature gas cooled reactor) indispensable moderated, reflection and construction materials. In order to use the safety, the nuclear reactor needs to be compact and uniform. Graphite although has the good performance of nuclear reaction, however, the ideal graphite crystal is the structure of two-dimensional sheet, carbon level direction strength greatly, and interlayer only weak intermolecular bonding combined showed obvious anisotropy. Therefore, the properties of the material can be adjusted by making isotropic graphite or by the method of the composite material. As an important material in the construction of nuclear power plants,…
