Q:How to solve the problem of graphite electrode being crushed during electrolysis
There's no way. It's an industrial problem, and that's how graphite works.
Q:Please senior doubts. The graphite electrode is used in the mold cavity In what case is graphite processing taken?
Because of the great loss of graphite electrode in finishing, it is not suitable to be used as finishing electrode material. Because of the small coefficient of thermal expansion of graphite, it can also be used as a big electrode material in perforation processing.
Q:The original battery is not necessary to form the electrode potential? Why can we use graphite as electrode only? No potential difference.
A galvanic cell is a device that converts chemical energy into electrical energy. Electron transfer not by oxidizing and reducing agents to complete the effective collision between, but the reducing agent loss electron oxidation reaction occurs in the anode, the electron transport to the anode through the external circuit, the oxidant to the anode electron reduction reaction, so as to complete the transfer of reductant and oxidant electrons.
Q:Is graphite electrode good for foreign trade?
Profits can be made for foreign trade. Even if you produce it yourself. Traders take big head. Own production. It's hard for you to play. If you have a client, we can work together
Q:What kinds of carbon are there?
Graphite electrode class can be divided into ordinary power graphite electrode according to the allowable current density. High power electrode and ultra high power electrode.
Q:In EDM, the electrodes are made of graphite and copper. Please tell us the difference between them
Graphite is characterized by coarse particles, fine particles and ultrafine particlesFor different processing, you can choose different particles, the smaller the particle size, the higher the accuracyCopper has good conductivity and thermal conductivity and is used in many occasionsBut there are many factors to consider in the choice between the two
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:Which department in the steel plant needs graphite in large quantities?
For steel and iron alloys, graphite electrodes are used, when powerful currents pass through electrodes into the melting zone of the electric furnace to produce an arcThe electric energy is converted into heat energy, and the temperature is increased to about 2000 degrees, so as to achieve the purpose of smelting or reaction. In addition, the electrolytic goldWhen the magnesium, aluminium and sodium are used, the anode of the electrolytic cell is also made of graphite electrode. The resistance furnace for carborundum is also made of graphite electrode as the burnerConductive material.
Q:800KVA and 12500 EAF transformer data graphite electrode furnace.
The graphite electrode must be roasted by a cathode or anode baking furnace, and a large amount of harmful gas and dust will be produced during the roasting process.
