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:Can Naiduo high temperature graphite
The reinforced graphite gasket is made of flexible graphite tape or flexible graphite and is molded into ring products of different sizes. Suitable for hot water, high temperature, high pressure steam, heat exchange liquid, nitrogen gas, organic solvent, hydrocarbon, low temperature liquid and other medium. Used in compressors, machines, pumps, valves, chemical instruments, instruments, etc..
Q:MITSUBISHI machine graphite electrode processing, how does not accumulate carbon?
The three is difficult cold start, is sparking difficult, not easy car, and finally the combustion chamber carbon Yan will cause a heavy cylinder knock, low speed and acceleration noise, causing damage to the piston and crankshaft, causing the engine temperature which can seriously affect the automobile safety. Emission standards exceeded, not only through the annual inspection, but also directly aggravate the pollution of the environment
Q:How much does a graphite electrode cost about a ton?
Electrode is divided into ordinary power motor, high power electrode, ultra high power electrode, the gap between the price is still relatively large
Q:Why use platinum ferroalloy instead of iron as electrode?
General industrial grade silicon dioxide, because the preparation technology is different, can be divided into two types, one is dry, sintered (Fume Type), a wet precipitation type (Precipitated Type), and two of the surface area, the surface with hydroxyl (-OH) are the same, in general, the former the latter is more, less, the two surface has the tendency of hydrophilic, as for lipophilic polymer, such as paint, rubber... Etc.,... If the silica surface pre rendered hydrophobic, has a good effect.
Q:Do electroplating experiments, graphite as an electrode, graphite how to pre process to ensure that the coating will not fall, resulting in increased color of the solution
Both of these will be a little bit absorbed, when plating, the anode and anode inside the syrup will run on the negative pole,
Q:Electrolytic salt water why use iron as a cathode, all with graphite can not?
When electrolyzed salt water is used, the cations in the solution (H+, ionized by H2O) are moved to the cathode by the electric field force, and electrons are generated at the cathode to produce H2 hydrogen, and the hydrogen H2 generated does not react with iron
Q:Which department in the steel plant needs graphite in large quantities?
Steelmaking department. The graphite electrode steelmaking is to enter the electric energy through the graphite electrode to the electric arc furnace, and takes the arc between the electrode end and the furnace charge as the heat source to carry on the steel smelting. The electric arc furnace takes electric energy as heat source, and can adjust the atmosphere in the furnace. It is very beneficial to smelt the steel which contains more easily oxidized elements. Smelting a variety of alloys
Q:What is the application of wire cutting with graphite electrode?
With the development of science and technology, the machine manufacturing technology has undergone profound changes. Due to the social demand for diversification of products is more intense, more varieties, small batch production increasing proportion in WEDM by traditional processing equipment has been difficult to adapt to the processing of high efficiency, high quality, diversified requirements, CNC technology should be used
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
