FAQ

  1. What is the consumption of your Electrode?

    The comsumption of Our Electrode can be below 1.0kg/mt, and the everage is 0.5kg/mt.

  2. What is the reason of the problem of broken?

    There are several reasons, such as: Amperage is too high, the connection is not good, etc.

Q:Graphitized coke, graphite, broken, mixed up, how to export?
Graphite electrode pieces in different data definition of graphite scrap is different, some data and literature of the graphite particles are called not great pieces of graphite (such as graphite) and some say that graphite products have a certain size, into a block of graphite broken, we are here to say Shi Mosui is second, often called as the graphite block. The production of graphite from graphite products, graphitization and machining process. Graphite waste used as an additive and as a conductive material in the steelmaking and casting industries.
Q:800KVA and 12500 EAF transformer data graphite electrode furnace.
Graphite project: Project Description: steel furnace and iron smelting furnace, ferrosilicon smelting, electrolytic aluminum and so on, all use large surface graphite electrode.
Q:Graphite electrode press device
Ultra high power graphite electrodes. Use of graphite electrodes with a current density greater than 25A / cm 2. Used primarily in ultra high power arc furnaces
Q:Graphite electrode in milling machine processing, dust is especially big, boot 5 minutes, workshop can not open the figure, what is the solution?
This is to use the dust collector, the graphite itself is a semiconductor, can not be electrostatic dust removal
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
Q:Is the anode of electrolytic water suitable for ordinary titanium wires?
The graphite is cheaper and easier to obtain, but the carbon electrodes sold in the general market are not very pure at most times. The experiment is done for a period of time, and the carbon is inexplicably broken, especially if you need to work for a long time. So, if your graphite electrode is of good quality, it's still graphite.
Q:What is the application of wire cutting with graphite electrode?
Machine: wire cutting wire, wire EDM, wire EDM wire is the cutting machine.
Q:What is the difference between SGL graphite electrode and graphite electrode in general?
In fact, the graphite electrode abroad (including Japan) in several ways than we can control the fine, one is pure, another is anisotropic (resistance, thermal conductivity ah) usually do some control, in the strength of domestic now is also doing well, but when we are comparing high quality products, general domestic products it is basically a piece of the indicators are poor
Q:What is the difference between pyridine type nitrogen and graphite type nitrogen?
High purity graphite is said to produce graphite electrode, ash is very low, generally below 10 million.
Q:Is graphite flammable?Why do I bake pencil cores with a fever that doesn't burn?
The temperature is not enough, the composition of graphite is carbon, of course, flammable, but each kind of object burning point is not the same, the nature of graphite is relatively stable, burning point is very high, cigarette lighter this temperature is certainly not burning up.Useful words, remember to adopt Oh, thank you ~!
