What is the Best Tool Material Effect for Graphite Electrode Processing?

Aug. 06, 2020

As a Graphite Electrodes Supplier, share with you. Graphite as an electrode refers to the use of petroleum coke and pitch coke as aggregates and coal pitch as binder, which are made by calcining, crushing and grinding, batching, kneading, molding, roasting, impregnation, graphitization and mechanical design and processing of different raw materials. A kind of high temperature resistant and graphite conductive composite material. Graphite rods are often used as electric heating elements in high-temperature vacuum furnaces. The maximum operating temperature can reach 3000℃. It is easy to oxidize at high temperatures. Except for vacuum, it can only be used in a neutral or reducing atmosphere. Its thermal expansion coefficient is small, thermal conductivity is large, resistivity is (8~13)×10-6 Ω·m, processability is better than SiC, MoSi2 rod, high temperature resistance, extreme cold and extreme heat resistance, good price Cheaper. Graphite electrodes are mainly made of petroleum coke and needle coke as raw materials, coal tar pitch as a binder, and are made by calcination, batching, kneading, pressing, roasting, graphitization, and machining. It releases electric energy in the form of electric arc in an electric arc furnace. The conductors used for heating and melting the charge can be classified into ordinary power, high power and ultra-high power according to their quality indicators. Graphite electrodes mainly include four types of ordinary power graphite electrodes, anti-oxidation coating graphite electrodes, high power graphite electrodes and ultra-high power graphite electrodes. Graphite block is a kind of artificial graphite, and artificial graphite is made by artificial heating of coke products. Generally, if it is purified to make high-purity or carbon fiber, the added value is high.

What material is good for graphite electrode machining tools?

Graphite has good strength, low thermal expansion coefficient, good cutting performance and good thermal conductivity at high temperatures, so graphite electrodes are widely used in metallurgy, electric furnaces, electric discharge machining and other fields. In the field of EDM, the development of new graphite electrode materials and their processing technology has expanded the application range of EDM and improved its performance. Compared with copper electrodes, graphite electrodes have the advantages of low electrode consumption, fast processing speed, good processing performance, high processing accuracy, small thermal deformation, light weight, easy surface treatment, high temperature resistance, high processing temperature, and strong electrode adhesion.
