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?: Electrical discharge machining (EDM) is a spark discharge in a liquid medium at a lower voltage range to meet the required shape and size.

Q: Use of graphite in steelmaking: Application of graphite electrode in smelting, alloy steel, iron alloy, graphite electrode, 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: Where is the graphite electrode scrap?: Atoms, ions, and electrons collide with each other in strong oscillatory motion to produce more electrons and ions.

Q: What is the graphite furnace electrode with a diameter of 400?: The variety and specifications of graphite electrodes used in modern EAF steelmaking are mainly determined by the technical parameters of the steelmaking furnace.

Q: Graphite graphite graphite graphite electrode what is the use?: Of course all conductive graphite gray, conductive powder is used for professional conductive, the conductivity is different, in order to achieve its electrical resistance value, the graphite powder of different particle by the ratio to reach the ideal value of resistance. Graphite powder is pure graphite powder, requirements of mesh consistent, high purity.

Q: What are the factors that affect the electrode wear rate of machine tools?: Influence of pulse interval on electrode wear. When the pulse interval is large, the electrode loss increases, which is due to the deterioration of the thermal effect condition and the damage of the "covering effect".

Q: Electrolysis of CuCl2 solutions with graphite electrodes: After energization, electrolysis occurs, not ionizationIonization does not require energization, and can occur in aqueous or molten state.

Q: Excuse me, why does the graphite electrode flake when electrolyzed salt water is used?: Device for electrolytic reaction. The electrolysis bath comprises a tank, an anode and a cathode, the majority of diaphragm separates the anode chamber and a cathode chamber. According to the different electrolyte aqueous solution electrolysis, molten salt electrolytic cell and nonaqueous solution electrolysis. When three kinds of direct current through the electrolytic cell, the anode oxidation the reaction solution and at the interface in the cathode and the electrolyte interface reaction, to produce the required products. To optimize the design of electrolytic cell structure, reasonable selection of electrode and diaphragm material is the key to improve the current efficiency, decrease cell voltage and energy saving.

Q: I used 12V direct current, graphite electrode electrolysis sodium sulfide solution, the anode produced a large number of black material, this is why ah?: The actual electrolysis of hydrogen sulfide, which produces no black, or impurities that are absorbed by the anode, is graphite, because the dots explain the loose particles that are absorbed on the surface

Q: How large is the permissible overload current per square millimeter of the graphite electrode cross section?: Overhead wires, radiating the best conditions, allowed the current largest. The insulated wire in the house is laid in the wall, which has the worst heat release conditions and the smaller permissible current, so there are different safety currents.
