With the increasing complexity of die geometry and the diversification of product application, the discharge accuracy of spark machine is required to be higher and higher. The advantages of graphite electrode are easy to process, high removal rate of EDM and small graphite loss. Therefore, some customers of group based spark machine abandon copper electrode

Graphite electrode is a kind of high temperature resistant graphite conductive material, which is made of petroleum coke, pitch coke as granular material, coal pitch as binder, through} kneading, molding, roasting, graphitization and machining. Graphite electrode is an important high-temperature conductive material for electric furnace steelmaking. It inputs electric energy to the electric furnace through graphite

First, the melting point of graphite electrode is very high, so it has high heat resistance. Graphite electrode materials can be divided into different grades according to the requirements of failure. At the same time, the selection of graphite electrode material is also the key factor, because the selection of material is suitable or not, the speed

Ultra-high power graphite electrode colloidal graphite is mainly used in lubrication, conductivity, sealing and other fields. Different types and types of colloidal graphite are needed in different industrial production fields. There are many kinds of colloidal graphite. Colloidal graphite includes 00 colloidal graphite, 0 colloidal graphite, 1 colloidal graphite and so on. Colloidal graphite lubrication is mainly

Roasting is one of the heat treatment processes in the industrial production of graphite sheets and graphite products. The roasting of raw products after moulding is indirectly heated with coke powder (or quartz sand) as protective medium in the roaster at a constant heating rate under the condition of isolating air. The heating time varies according
