7. FAQ

We have organized several common questions for our clients，may help you sincerely：

①How about your Warranty of Graphite Electrode ？

Warranty: 1-Year for the whole light. Warranty is based on correct storage, installation, using and maintenanc

②How to guarantee the quality of the products of Graphite Electrode ？

We have established the international advanced quality management system，every link from raw material to final product we have strict quality test；We resolutely put an end to unqualified products flowing into the market. At the same time, we will provide necessary follow-up service assurance. We have D&B report and you could check details information for our company.

③How long can we receive the product after purchase of Graphite Electrode ?

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

Q:What is the role of the Pt electrode? What is the difference between the graphite electrode and the graphite electrode?: In the electrochemical process, the electrode should not affect the reaction on the working electrode, so platinum and graphite are often chosen

Q:Will the brush grease not short-circuit the commutator?: Specifically: between motor brush and collector plus grease is redundant, but it is very harmful, fat instead will not play the role of good lubrication, it will destroy the good lubrication brush itself, not superfluous".

Q:After electrolysis of CuCl2 solution with graphite electrode for a period of time, we can observe that the graphite surface attached to the DC power supply is attached to the red material,And will the color of the solution be deep or shallow?: Copper ions move toward the cathode, which is the graphite rod connected to the negative electrode of the DC power supply. The color of the solution becomes shallower

Q:I remember the more lively metal, the electron?: C metal is copper, because a dilute sulfuric acid into the H2 precipitation, then definitely not copper. And the inactive first precipitate

Q:Can high-purity graphite be used as an electrode?: High purity graphite can be used as electrode, high purity graphite as electrode has many advantages. According to the research of Qingdao Huatai graphite, we can see: 1, high purity graphite electrode is quick in opening and good in air permeability;

Q:How long is the graphite electrode machining cycle?: Industrial graphite is hard and brittle, and the tool is worn more seriously during machining. It is generally recommended to use carbide or diamond coated cutting tools. When the graphite is rough, the cutter can be directly worked on the workpiece. When it is finished, it is necessary to use light knife to walk quickly to avoid the occurrence of chipping and chipping

Q:What's the use of carbon?: Common power graphite electrode. Allows the use of current density of less than 17A/ cm 2 graphite electrode, mainly used for steelmaking, smelting silicon, yellow phosphorus and other ordinary power furnace.

Q:The graphite electrode made by the machining center adopts cooling method, which is water cooled, oil cooled and blow cold. Which is good?: Of course you do is oil cold if not toxic cooling but although graphite powder lubrication seems to have damage to the CNC, that someone with a water-cooled graphite again even with saponification liquid will rust and easy cleaning

Q:What about graphite electrodes for steel mills?: 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:Graphitized coke, graphite, broken, mixed up, how to export?: Graphite fossil oil coke is the best smelting carburizing agent. In the steel-making industry, to produce good steel, there must be good raw materials, including good carburizing agent, and the graphitization of petroleum coke is the best carburizing agent.
