5. FAQ

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

①How about your Warranty of Graphite Electrode for Arc Furnaces？

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 Graphite Electrode for Arc Furnaces？

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?

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

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:How should carbon deposits be treated?: At certain temperature, can make alloy and carbon can react in the engine surface coated with a layer of graphene film, graphene nano particles can fill the pores, wear scratches, on the friction surface repair function.

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?: The oxygen will react with the graphite and the gas will dissolve.The iron has been oxidized.

Q:Why should the carbon brush for the trolley be made of graphite?: Graphite conducts electricity and is self lubricant, resistant to wear. As for why, high school chemistry textbooks have ah.

Q:The difference between graphite electrode and graphite rod: Graphite rod for non metal products, as carbon arc gouging cutting process in an essential pre welding cutting supplies, is composed of carbon and graphite with appropriate adhesive, through the extrusion, the temperature of 2200 DEG C after baking rotary plating a layer made from copper, high temperature resistance, good electrical conductivity, is not easy fracture, suitable for metal cutting into required shape.

Q:Use of graphite in steelmaking: Graphite can be used as an agent for carburizing in the steel making industry. Carburizing uses a wide range of carbonaceous materials, including synthetic graphite, petroleum coke, metallurgical coke, and natural graphite. Worldwide, the use of graphite for carburizing is still one of the main uses of earth like graphite.

Q:Graphite powder produced by graphite electrode and what we usually call graphite is a kind of thing?: In the electric arc furnace, the electric energy is released in the form of an arc, and the conductor is heated and melted. According to the quality index, the conductor can be divided into ordinary power, high power and ultra high power.

Q:Graphite electrode press device: High power graphite electrodes. Graphite electrodes with a current density of 18 ~ 25A / cm 2 are allowed. They are mainly used in high power arc furnaces for steelmaking

Q:Classification, uses and manufacturers of graphite electrodes: Graphite as electrode(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.(2) lighter weight: the density of graphite is only 1/5 of copper. When large electrode is used for discharge machining, it can effectively reduce the burden of machine tools (EDM). It is more suitable for large-scale die applications.

Q:Do electroplating experiments, graphite as an electrode, graphite how to pre process to ensure that the coating will not fall, resulting in increased color of the solution: This graphite will eventually wear out, even if you use the nickel plate directly, the nickel plate is still wearing, but compared to graphite than the much better. You should ask the question, the brush plating industry association, oh, they study this stuff all day long.
