Graphite electrode introduction
Graphite electrodes are used mainly in electric arc furnace steel production. They are presently the only products available that have the high levels of electrical conductivity and the capability of sustaining the extremely high levels of heat generated in this demanding environment. Graphite electrodes are also used to refine steel in ladle furnaces and in other smelting processes.

- Q: What are the factors affecting the service life of graphite electrode in ultra high power arc furnace?
- China's graphite electrode quality standard (YB/T4090-2000) to evaluate the quality of the ultra high power graphite electrode is defined 6 physicochemical indexes, including resistivity, flexural strength, elastic modulus, bulk density and linear expansion coefficient as the quality evaluation index, ash as a reference index.
- Q: Thermal expansion coefficient of graphite
- In the graphite electrode, the national standard, the volume density in more than 1.60 of both high power graphite electrode, of course because of the national standard index is low now, the volume density of normal power graphite electrode factory can reach 1.65, such as Chengde and long carbon factory.
- Q: What are the skills of hardfacing process for wear-resistant alloy powder blocks?
- The power supply adopts the DC arc welding machine with steep drop characteristic, adopts the positive connection method, the electrode is negative, and the electrode is a high strength spectrum pure graphite rod,
- Q: Graphite powder produced by graphite electrode and what we usually call graphite is a kind of thing?
- Coal tar pitch as binder is made by calcination, batching, kneading, pressing, roasting, graphitization and machining
- Q: How can the graphite powder be processed into high quality carburizing agent? Thank you
- Basically, it can no longer be a "good" carburizing agent
- Q: Graphite electrode press device
- Graphite electrode is mainly in the petroleum coke and needle coke, coal tar pitch as binder, calcination, mixing, kneading, pressing, baking and graphitization, and made the processing machine, is a conductor in an electric arc furnace to form arc release electricity for heating and melting of the charge, according to the quality index level, can is divided into ordinary power, high power and ultra high power.
- Q: After vacuum melting of quartz crucible, there are three graphite electrode rods. What's the adjustment?
- Or did you adjust the electrode when it was installed? There are two electrode distance, two away, causing melting after different lengths.
- Q: How can I electroplate iron? I would like to use graphite as an electrode. Iron is plated on graphite with iron solution, so it can be processed into iron parts. I wonder if it can be done
- Iron plating can be, with 2 valence iron, but on the graphite joint force is good, it is difficult to say, electroplating is bad, peeling is also common. Relatively speaking, iron parts on nickel plating is relatively simple, also more applicable
- Q: What do carbon products include?
- High power electrode and ultra high power electrode. The carbon block can be divided into blast furnace carbon block, aluminum carbon block and electric furnace block. Carbon products can be divided into carbon products, graphite products, carbon fibers and graphite fibers according to the depth of processing. Carbon products can be divided into graphite products, carbon products, carbon fibers and special graphite products according to the raw materials and the production process. Carbon products according to their ash content, and can be divided into multi gray products and less ash products (including ash below l%).
- Q: How large is the permissible overload current per square millimeter of the graphite electrode cross section?
- 9A/mm2 safety current should be bare overhead, 5A/mm2 is obviously insulation lines, the indoor environment standards.
