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: Thermal expansion coefficient of graphite: Thermal expansion coefficient (100 degrees Celsius --600 degrees Celsius) diameter 200--500 graphite electrode body is not greater than 2.410 of the negative four times per degree Celsius

Q: Use of graphite in steelmaking: At present in the world (MgO-C brick raw material for graphite and magnesium) as refractory material, has been widely used in steelmaking, has become a traditional use of graphite.

Q: Where is the graphite electrode scrap?: Finally, a bright white Ar-ICP discharge is formed, especially like a drop of water droplets.

Q: What is the application of wire cutting with graphite electrode?: With the development of science and technology, the machine manufacturing technology has undergone profound changes. Due to the social demand for diversification of products is more intense, more varieties, small batch production increasing proportion in WEDM by traditional processing equipment has been difficult to adapt to the processing of high efficiency, high quality, diversified requirements, CNC technology should be used

Q: Can Naiduo high temperature graphite: The reinforced graphite gasket is made of flexible graphite tape or flexible graphite and is molded into ring products of different sizes. Suitable for hot water, high temperature, high pressure steam, heat exchange liquid, nitrogen gas, organic solvent, hydrocarbon, low temperature liquid and other medium. Used in compressors, machines, pumps, valves, chemical instruments, instruments, etc..

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: What is anodized graphite?: Anodized graphite is mainly used for making brushes. The utility model has the advantages of good performance, high resistance coefficient and contact voltage, favorable for suppressing spark, and wide application range, and can be used for various types of motors and motors with more difficult commutation conditions.

Q: What is the composition of petroleum coke and what is its use?: Petroleum coke can be used for the manufacture of graphite, smelting and chemical industries, depending on its quality. For example, the quality of cooked sweet coke coke, mainly used in the manufacture of ultra high power graphite electrode and some special carbon products; needle coke in steelmaking industry is an important material new technology development of EAF steelmaking.

Q: How about graphite electrode high-temperature oxidation resistant coating?: Can be used, temperature characteristics of nano composite ceramic coating is more stable, and nano composite ceramic nano high temperature oxidation resistant coatings of different graphite products according to the use conditions, can the temperature of 1600 degrees, forming a dense coating on graphite coated with rust, corrosion, high temperature resistance, oxidation resistance, wear resistance and other properties.

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.
