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: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?
Anodic iron is directly oxidized without oxygen generation
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:Please senior doubts. The graphite electrode is used in the mold cavity In what case is graphite processing taken?
Graphite electrode has better machining stability and high production efficiency. It is easy to be used as EDM electrode material in EDM when it is processed with long pulse width and high current.
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 to solve the problem of graphite electrode being crushed during electrolysis
This graphite electrode is so true because it causes gas to expand and disintegrateTantalum electrodes can be solved and not expensive
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:Classification of graphite electrodes
A graphite electrode that allows current densities greater than 25A/ cm 2 is allowed. Mainly used in ultra high power steelmaking arc furnace.
Q:How can hydrogen be produced by electrolysis of sodium hydroxide with graphite as an electrode?
You can think so, since sodium has been reduced, so there is always an atom is oxidized, it can only be oxygen oxidation reaction
Q:Is graphite flammable?Why do I bake pencil cores with a fever that doesn't burn?
In anaerobic conditions, the ignition temperature is at least above 3000 degrees. There are many types of graphite, different types of ignition points, and the burning point of pyrolytic graphite...
