Q:What is the reason that the current cannot be increased when the graphite electrode is used for anode electrolysis?Add calcium chloride and sodium bicarbonate into electrolytic water
The reason is that the resistance increases continuously, the number of ions is limited, and the conductivity is limited
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:What do carbon products include?
Carbon products can be divided into graphite electrode, carbon block, graphite anode, carbon electrode, paste, electric carbon, carbon fiber, special graphite, graphite heat exchanger and so on according to the use of products. Graphite electrode class can be divided into ordinary power graphite electrode according to the allowable current density.
Q:Can high-purity graphite be used as an electrode?
The thin and deep bone electrode can not be deformed, and the pure graphite electrode is brittle. It is better to break or deform, and can bear high temperature without deformation.
Q:Why is the production of one ton of ultra high power graphite electrode requires 1.05 tons of coke?
After calcined to eliminate ash and volatile part of the points in this process will be a lot of weight loss, in the process of crushing mixing in process of baking or graphite in high temperature heat treatment, another part of the impurities were excluded, so the raw material is higher than the rate of finished products.
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 application of wire cutting with graphite electrode?
Greatly shorten the preparatory time of mechanical processing, and improve the level of automation of the whole process of machining, and also enhance the ability of the manufacturing system to adapt to changes in production conditions.
Q:What are the factors affecting the service life of graphite electrode in ultra high power arc furnace?
China's graphite electrode quality standard (YB/T4090-2000) to evaluate the quality of the ultra high power graphite electrode is defined 6 physicochemical indexes, including resistivity, flexural strength, elastic modulus, bulk density and linear expansion coefficient as the quality evaluation index, ash as a reference index.
Q:What are pyrolytic graphite electrodes used for?
(1) the processing speed is faster: normally, the mechanical processing speed of graphite can be 2~5 times faster than copper, while the discharge processing speed is 2~3 times faster than copper;More material is not easily deformed: obvious advantages in the processing of thin electrodes; copper softening point at about 1000 degrees, easily deformed by heat; graphite sublimation temperature is 3650 degrees; the thermal expansion coefficient of copper is only 1/30.
Q:Will the brush grease not short-circuit the commutator?
Graphite, on the other hand, has good lubrication. The graphite base electrode will form a layer of carbon film when it rotates on the surface of the motor commutator. It can reduce the friction coefficient between the brush and the commutator and reduce the wear of the commutator effectively.
