Q: What is the striking electrode in the die making? Where is the technical point?
The electrode in die processing is edm.The discharge produces sparks and forms a "corrosion" to the other pole. The method of machining parts (dies) using this phenomenon is called edm.
Q: How to solve the problem of graphite electrode being crushed during electrolysis
I can only use the experience of the past to tell you that if you want to save money easily, the time can be considered as the costA thick graphite stick; inexpensive
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 first answer to the equation above is quite right, or it may be that a layer of calcium carbonate is attached to the surface of the electrode, which prevents the electrode from conducting and leads to an increase in resistance
Q: Does the silicon carbide heat plant require a fine structure graphite electrode? What kind of graphite products do you need?
But because the silicon carbide is too hard, it is difficult to machining, good workability, such as non special requirements, using graphite instead of silicon carbide, instead of the effect is not good, but can use a silicon carbide, easy processing, small life than silicon carbide.
Q: The reason why graphite is used as electrode
Graphite has good thermal stabilityThe softening point of copper in 1000 degrees, easily deformed by heat, the melting point of graphite is 3850 + 50 DEG C, the boiling point of 4250 DEG C, even after the ultra high temperature arc ignition, the weight loss is very small, the thermal expansion coefficient is small. The strength of graphite increases with the increase of temperature, and the strength of graphite is doubled at 2000 degrees centigrade. In comparison, the thermal expansion coefficient of graphite material is only 1/30 of copper material.
Q: Which department in the steel plant needs graphite in large quantities?
The variety and specifications of graphite electrodes used in modern EAF steelmaking are mainly determined by the technical parameters of the steelmaking furnace. 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: Please senior doubts. The graphite electrode is used in the mold cavity In what case is graphite processing taken?
Instead of copper as discharge material.1. Electrode design1 can reduce the number of individual electrodes / can be made into a composite electrode2, it can save the electrode clamp system and save the cost2, the electrode processing1, high speed milling rough processing copper block 3 times2, high-speed milling finishing faster than copper 5 times3. Good machinability4, complex geometric modeling can be realized3, light weight, its density is less than 1/4 of copper1, good thermal stability (without deformation)2 can reduce the number of individual electrodes / can be made into a composite electrode3, without deburring4. The electrode is easy to clamp4 、 electric discharge machining EDM1, roughing, the electrode loss is small2, high work removal rate3 can reduce the number of individual electrodes / can be made into a composite electrode4. No pollution to the environment in the electrolyte5, light weight, its density is less than 1/4 of copper6, excellent thermal stability, the electrode does not change7, the fine graphite electrode can be used to produce high quality workpiece surfaceDifferent grades of graphite materials can be used for processing different workpieces
Q: How can the graphite powder be processed into high quality carburizing agent? Thank you
If you are through the material can also be screened and then sold, usually 1-5 of the particle size, fine powder can only add adhesive column
Q: Graphite electrode press device
(1) ordinary power graphite electrode, using graphite electrode with current density lower than 17A / cm 2, is mainly used in steel-making, smelting silicon, refining yellow phosphorus and other common power electric stove(2) anti oxidation coating graphite electrode. The surface is coated with an anti oxidation protective layer of graphite electrode to form a protective layer which has both conductive and high-temperature oxidation resistance, thus reducing the electrode consumption during steelmaking
Q: What are the factors that affect the electrode wear rate of machine tools?
Effect of peak pulse current on electrode wear. The peak current has a great influence on electrode wear, but the curves are very different due to the different materials of the electrode and the workpiece. In the copper electrode machining steel, general peak current, electrode loss is also large, but also have a great relationship with the pulse width, so in practice, we should choose different peak current of different area according to the data processing technology of power supply and discharge pulse width, can make the processing speed is high, and the electrode loss small.
