In the purchase of product within three working days, We will arrange the factory delivery as soon as possible.

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: 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: Because in the process of electrolysis of water in cathode electron generated hydroxyl, the alkaline solution increased. But with the hydroxyl reaction of sodium carbonate and sodium bicarbonate, carbonate and calcium ions exist at the same time, must produce the precipitation of calcium carbonate, the ion in the solution is reduced, thereby conductive resistance increases. Thus weakened over time current cannot be raised

Q: Specification for graphite electrodes commonly used in steel works: In general, the graphite electrode used in steelmaking furnace is mostly made of ordinary power and high power graphite electrode. Now, the use of ultra high power graphite electrode increases year by year, accounting for almost half of the graphite electrode.

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: 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: Graphite graphite graphite graphite electrode what is the use?: Natural graphite electrode is the main raw material with graphite, high purity flake graphite powder or high carbon flake graphite powder as raw material, because carbon or graphite powder purity is high, the effect of conductive graphite powder is better in smelting alloy steel, iron alloy, electrode graphite powder as raw material. The electrode produced, then the strong current through the melting zone, the arc electrode into the electric furnace, the electrical energy into heat, the temperature rises to 2000 degrees Celsius, so as to achieve the purpose of melting or reaction.

Q: Why is graphite a negative pole and copper is an anode?: The process of causing a chemical change by passing through a substance. Chemical change is the process in which material is lost or obtained by electrolysis (oxidation or reduction). Electrolysis is performed in an electrolytic cell. The electrolytic cell is composed of two electrodes, yin and Yang, which are respectively immersed in the solution containing positive and negative ions. The current into the negative electrode (cathode), are positively charged ions migrate to the cathode solution, and with the combination of electronic elements, become neutral or negatively charged molecules; negative ion transfer to another electrode (anode), electrons are given into neutral elements or molecules.

Q: What is the difference between SGL graphite electrode and graphite electrode in general?: Can not say that the more detailed the better, is relative, must be uniform within the range (after all, it is very important to choose the aggregate), such as spectral pure graphite, is not due, he is a lot of technology to producing stains, then burning, and then producing stains, the strength is quite good,

Q: How large is the permissible overload current per square millimeter of the graphite electrode cross section?: 9A/mm2 safety current should be bare overhead, 5A/mm2 is obviously insulation lines, the indoor environment standards.
