Q:The difference between graphite electrode and graphite rod

The difference between an electrode and a rod is that the electrode has a lead conductor, and the rod is not.

Q:Classification of graphite electrodes

A graphite electrode with a current density of 18~25A/ cm 2 is used, which is mainly used in steel-making of high power arc furnace.

Q:What is anodized graphite?

Electrochemical graphite is made of graphite, coke and other raw materials, placed in the high temperature of more than 2500 degrees in the furnace, processed into products.

Q:What are the factors that affect the electrode wear rate of machine tools?

Effect of processing voltage on electrode wear. The processing voltage is the average voltage between the discharge time and the gap. When the voltage is lower than the power supply voltage (voltage) 25%, electrode loss will increase, which is due to the electrode and the workpiece is too close, the discharge column energy is too large, the electrodes generate heat radiation is too strong, at the same time, there are a large number of continuous arc discharge. But the working voltage is too high (partial load processing), bad conditions of thermal effect in the gap, is not conducive to the adsorption of copper electrode of carbon graphite, destroy the covering effect. Similarly, the electrode loss increase, therefore, corresponding to different processing standards should be selected to adjust the discharging gap voltage.

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:Is the anode of electrolytic water suitable for ordinary titanium wires?

Graphite firstFirst of all, the titanium electrode is usually not pure titanium, it should be titanium with a metal oxide coating. Secondly, the advantages of the titanium electrode is mainly to save electricity, the corrosion resistance of carbon is much stronger than that of industrial production, if the meaning is relatively large, but it is still in laboratory experiments, electrolysis of water, not what meaning.

Q:What are the losses in graphite electrode?

In what environment is the loss, friction, or in the case of high temperature, high temperature will be oxidized, and if in the case of friction, you can first use more wear-resistant graphite material. So please ask this question clearly, and then answer you, thank you.

Q:How does graphite produce solar cells?

The team at the Massachusetts Institute of Technology has confirmed that electrodes based on graphene and ITO devices are comparable in efficiency. Although the power conversion efficiency of graphene is 4.2% lower than that of a general silicon cell, it will be competitive for special use in the future.

Q:The graphite electrode made by the machining center adopts cooling method, which is water cooled, oil cooled and blow cold. Which is good?

Use oil cold. Air cooling will cause graphite dust flying, on the one hand, toxic, on the one hand there are security risks (caused by circuit short circuit). Water cooling is virtually out of use, taking into account the maintenance and maintenance of the CNC.

Q:In EDM, the electrodes are made of graphite and copper. Please tell us the difference between them

For example, the electrode is large, and this time it is necessary to consider whether the weight of the electrode is up to standard and, if so, the preferred graphite electrode
