- Q: Why graphite can be used as conductive material?
- Widely used as electrode, graphite, carbon brush, carbon nanotubes, mercury rectifier cathode, graphite gasket, telephone parts, TV tube coating and so on in the electrical industry. The most widely used in the smelting of graphite electrode, 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 around, so as to achieve the purpose of melting or reaction. In addition, in the electrolysis of metal, magnesium, aluminum and sodium, the anode of the electrolytic cell is also made of graphite electrode. The resistance furnace used for the production of rigid sand is also made of graphite electrode as the conducting material of the furnace head.
- Q: After electrolysis of CuCl2 solution with graphite electrode for a period of time, we can observe that the graphite surface attached to the DC power supply is attached to the red material,And will the color of the solution be deep or shallow?
- Copper ions move toward the cathode, which is the graphite rod connected to the negative electrode of the DC power supply. The color of the solution becomes shallower
- Q: What is the graphite furnace electrode with a diameter of 400?
- With the development of EAF steelmaking technology, the steel-making technology is developing towards large scale and ultra high power. The graphite electrode is mainly made of large size graphite electrode and ultra high power graphite electrode.
- 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: In EDM, the electrodes are made of graphite and copper. Please tell us the difference between them
- Graphite is characterized by coarse particles, fine particles and ultrafine particlesFor different processing, you can choose different particles, the smaller the particle size, the higher the accuracyCopper has good conductivity and thermal conductivity and is used in many occasionsBut there are many factors to consider in the choice between the two
- Q: What kind of asphalt is better for natural graphite coating?
- Special graphite mainly to high quality petroleum coke as raw material, coal tar or synthetic resin as binder, the raw material preparation, mixing, kneading, pressing, crushing, mixing, molding, roasting, soaking, repeatedly repeated purification and graphitization, and made the processing machine. It is generally used in the aerospace, electronics and nuclear industry sectors. It includes pure graphite, high purity, high strength, high density and pyrolytic graphite.
- Q: What are the factors that affect the electrode wear rate of machine tools?
- Influence of pulse interval on electrode wear. When the pulse interval is large, the electrode loss increases, which is due to the deterioration of the thermal effect condition and the damage of the "covering effect".
- Q: 800KVA and 12500 EAF transformer data graphite electrode furnace.
- The graphite electrode must be roasted by a cathode or anode baking furnace, and a large amount of harmful gas and dust will be produced during the roasting process.
- Q: Excuse me, why does the graphite electrode flake when electrolyzed salt water is used?
- For example, according to connection of the electrode, which can be divided into two types of unipolar and bipolar type electrolyzer (see photo). The electrode is connected with the DC power supply parallel polarity monopolar electrolyzer, electrodes on both sides of the same, at the same time as anode or cathode. At the same time as the positive and negative electrode bipolar type electrolyzer ends respectively with DC power supply connected, as anode or cathode. The current through the electrode through the electrolysis cell in series, each side of the intermediate electrode as the anode, the other side is the cathode, so it has a bipolar electrode. When the total area at the same time, the current bipolar type electrolyzer is small, high voltage DC power supply, the required investment ratio monopolar, bipolar type filter press used. The general structure, more compact. But easy to leakage and short circuit, slot structure and operation management is more complex than the monopolar type. The monopolar electrolyzer section is generally rectangular or square, cylindrical covers a large, empty The utilization rate is low and the adoption rate is less
- Q: What is the composition of petroleum coke and what is its use?
- Medium sulphur and common cooked coke; used in large quantities for aluminium smelting. High sulfur, ordinary coke is used in chemical production, such as the manufacture of calcium carbide, silicon carbide, etc., but also as a metal casting and other fuels. Most of the petroleum coke produced in China belongs to low sulfur coke, which is mainly used for smelting aluminium and making graphite.
