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: Is graphite electrode good for foreign trade?: Profits can be made for foreign trade. Even if you produce it yourself. Traders take big head. Own production. It's hard for you to play. If you have a client, we can work together

Q: How to improve the efficiency of graphite electrode milling, please tell me: When the tool is broken, it will not only stop the continuous processing of the steel, but also affect the quality of the product, which will lead to the scrap of the parts and the waste of the material. Considering the foreseeable future, the graphite electrode will occupy a high position, usually used equipment for processing graphite electrode the highest efficiency mold manufacturers will unremittingly, expand and between those determined to use the hard steel processing manufacturer competition gap. The foundation of micro cutting tools, in terms of graphite electrodes, is one of its most magical words: "high speed."". The spindle speed of the high speed machining center is up to 30000~60000r/min, and the feed speed can be increased to shorten the processing period and improve the quality of the surface and edge. The motor needed to drive this type of spindle is relatively small and light, which helps to reduce cutting power and reduce tool breakage. This is critical because many of the electrodes are complex, and their production involves small, easily broken micro tools (see Figure 1).

Q: The use of graphite as an electrode in alumina electrolysis: The technical knowledge of electrolytic aluminum, cleaning and maintenance of alumina equipment, you can search for Baidu on the green, looking for.

Q: Specification for graphite electrodes commonly used in steel works: The variety and specifications of graphite electrodes used in modern EAF steelmaking are mainly determined by the technical parameters of the steelmaking furnace. With the development of EAF steelmaking technology, the steel-making technology is developing towards large scale and ultra high power. The graphite electrode is mainly made of large size graphite electrode and ultra high power graphite electrode.

Q: Synthesis techniques of carbon nanotubes: Catalytic pyrolysis is one of the widely used methods for preparing carbon nanotubes. The method mainly uses transition metal as catalyst, and is suitable for large-scale preparation of carbon nanotubes. The content of carbon nanotubes in the products is higher, but the defects of carbon nanotubes are more.

Q: Which department in the steel plant needs graphite in large quantities?: 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: MITSUBISHI machine graphite electrode processing, how does not accumulate carbon?: Carbon deposition can cause insufficient combustion of gasoline and cause engine chattering.

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?: Graphite electrodes react with oxygen to form carbon dioxide, soluble in water

Q: Graphite electrode press device: Graphite electrode is mainly in the petroleum coke and needle coke, coal tar pitch as binder, calcination, mixing, kneading, pressing, baking and graphitization, and made the processing machine, is a conductor in an electric arc furnace to form arc release electricity for heating and melting of the charge, according to the quality index level, can is divided into ordinary power, high power and ultra high power.

Q: How do graphitized electrodes differentiate between high power and low power?: In electrolysis industry, using graphite anode plate as the anode has a history of more than 100 years, the metal anode is in recent decades, the research and application of metal anode in China late last century, only in 70s the technology related to the research and experiment of metal anode, anode on electrolysis industry, mainly through the silver (2%) (0.5%): low silver lead silver alloy, lead and silver tin antimony alloy, lead calcium alloy and lead silver alloy adding nucleating agents and several stages.
