Production Description:

Graphite electrode is made from the domestic first petroleum coke and high quality needle coke and widely used in the electric arc furnaces for production of alloy steels, metal and other nonmetallic materials, etc. The graphite electrodes include regular power, high power, super high power, ultra high power and square electrode. The range of diameters covers from 200mm to 700mm. Our products own the following characteristics: low electric resistance, good electric and thermal conductivity, high oxidation resistance, greater resistance to thermal and mechanical shock, high mechanical strength, high machining accuracy.

China Graphite Electrode for EAF Furnace with Very Good Quality

Q: Why use platinum ferroalloy instead of iron as electrode?: Silica (Silica) is widely used in paint, ink, plastic, rubber and cosmetics, are often added to increase the performance of silica, such as oil absorption, extinction, strengthen the mechanical... Etc., and can reduce the cost of...

Q: What is the difference between pyridine type nitrogen and graphite type nitrogen?: The fine structure graphite is the raw material used in the production of graphite electrode. The particle size is relatively small, generally below 0.5.

Q: Graphite electrode specifications, graphite electrode manufacturers which good?: Graphite electrode has good electrical and chemical stability. It has high mechanical strength, low impurity content and good vibration resistance at high temperature. It is a good conductor of heat and electricity. Qingdao Chenyang graphite graphite electrode quality is good, they are a direct manufacturer of graphite electrode. Hope to be of some help to you.

Q: How should carbon deposits be treated?: It is very necessary to clean the throttle valve, clean the nozzle, and clean the carbon in the engine cylinder! However, in order to reduce the trouble of cleaning, it is best to join the regular application of graphene Moqi additive in lubricating oil for engine.

Q: The graphite electrode made by the machining center adopts cooling method, which is water cooled, oil cooled and blow cold. Which is good?: In addition, the infiltration of water on graphite is not good, can not get the effect of dust removal. Now there are special graphite machine, sealing system. Air-cooled can be used, after all, the best air-cooled.

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: Jiqiu conductive graphite electrode, how to compare with copper is relatively large resistance value?: Look at what kind of graphite electrode you need. Now, the resistivity of ordinary power graphite electrode in our factory is 7.5-8.5. It is not clear that the graphite electrode is dipped in 6--7.3. copper

Q: Excuse me, why does the graphite electrode flake when electrolyzed salt water is used?: The structure of the electrolytic cell is different when the electrolytic cell is constructed with different electrolytes

Q: I remember the more lively metal, the electron?: C is a salt solution of copper metal because copper is first reduced to a single element on a graphite electrode.Moreover, the addition of dilute sulfuric acid has a H2 emission, then a H of the previous metal.
