FAQ
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.
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: How to improve the efficiency of graphite electrode milling, please tell me
- There are many factors that determine the need to continue producing graphite electrodes, so high-speed machining has become a key manufacturing process in the die manufacturing industry. Compared with the time required for the milling of graphite electrodes, the processing of high rigidity hard steel still takes longer. When milling dies, cavities, and complex 3D surfaces on hard steel, radial runout errors and tool deviations often result in fracture of the tool. When the tool is broken, it will not only stop the continuous processing of the steel, but also affect the quality of the product, which will lead to the scrap of the parts and the waste of the material.
- Q: Use of graphite in steelmaking
- Application of graphite electrode in smelting, alloy steel, iron alloy, graphite electrode, the strong current through the melting zone, the arc electrode into the electric furnace, the electrical energy into heat, the temperature rises to 2000 degrees Celsius, so as to achieve the purpose of melting or reaction.
- Q: How to solve the problem of graphite electrode being crushed during electrolysis
- There's no way. It's an industrial problem, and that's how graphite works.
- 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 ~!
- Q: The use of graphite as an electrode in alumina electrolysis
- The technical knowledge of electrolytic aluminum, cleaning and maintenance of alumina equipment, you can search for Baidu on the green, looking for.
- Q: Specification for graphite electrodes commonly used in steel works
- In general, the graphite electrode used in steelmaking furnace is mostly made of ordinary power and high power graphite electrode. Now, the use of ultra high power graphite electrode increases year by year, accounting for almost half of the graphite electrode.
- Q: The original battery is not necessary to form the electrode potential? Why can we use graphite as electrode only? No potential difference.
- External electronic wire and the directional movement of ions in the solution of the directional movement between the poles of a closed loop, so that the two electrode reaction, electron transfer process, ordered a current converting chemical energy to electrical energy.Attention, here, "the ion does not go ashore, the electron does not enter the water"." That is the external circuit of graphite electrode is composed of electron flow and electrolyte ion flow; graphite electrode is to produce voltage and electrolyte, and to provide or absorb electrons
- Q: Electrolytic water solution, two electrodes are graphite electrode, the negative electrode can produce large amounts of hydrogen, the anode does not produce half of oxygen, and only a small amount of it?
- Graphite electrodes react with oxygen to form carbon dioxide, soluble in water
- 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: 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.
