Q:Will the brush grease not short-circuit the commutator?

The brush of motor is usually made of pure graphite electrode, electrochemical graphite electrode and metal fossil ink electrode material. Because it contains graphite, it has conductive effect on the one hand

Q:How do graphitized electrodes differentiate between high power and low power?

In an electrolytic cell, the current from a class called graphite anode plate into the electrolyte electrolysis industry, the anode is made of plate shape, so called graphite anode plate, widely used in electroplating, wastewater treatment, industrial anti-corrosion equipment or special materials.

Q:After vacuum melting of quartz crucible, there are three graphite electrode rods. What's the adjustment?

The shorter one is the farther away from the other, and the shorter one is the shorter one

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?

During electrolysis, cations move toward the cathode, electrons are reduced at the cathode, anions are moved toward the anode, electrons are lost at the anode and oxidized. And you use both sides of the graphite rod, is inert electrode, so there will be no copper ions added to the solution, copper in the solution of consumption, the color of natural shallow.

Q:National standard for graphite electrodes

Page 7 the international standard specifies the shape, dimensions and tolerances, technical requirements, test methods, packaging, marking, storage, transportation and quality certificates of graphite electrodes. This standard applies to high quality petroleum coke, asphalt, coke as the main raw material, through molding, roasting, impregnation, graphitization and mechanical processing made of, power supply arc furnace as conductive material of ordinary power graphite electrode. Common power graphite electrode GB

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: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:How long is the graphite electrode machining cycle?

Industrial graphite is hard and brittle, and the tool is worn more seriously during machining. It is generally recommended to use carbide or diamond coated cutting tools. When the graphite is rough, the cutter can be directly worked on the workpiece. When it is finished, it is necessary to use light knife to walk quickly to avoid the occurrence of chipping and chipping

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: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.
