FAQ

①How about your company？

A world class manufacturer & supplier of castings forging in carbon steel and alloy steel，is one of the large-scale professional investment casting production bases in China,consisting of both casting foundry forging and machining factory. Annually more than 8000 tons Precision casting and forging parts are exported to markets in Europe,America and Japan. OEM casting and forging service available according to customer’s requirements.

②How to guarantee the quality of the products？

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.

Q: Where is the graphite electrode scrap?: Vortex ring formed in a highly ionized internal ICP can be regarded as the secondary coil of the transformer is only one turn, and the work coil water is equivalent to the primary winding of the transformer, the coupling between them, the strength and direction of the magnetic field varies with time, the electronic and ionic field acceleration continuously changes its direction of motion. Lead to Joule heating effect and incidental ionization. This gas forms a new and stable "electric flame" light source in the quartz torch tube in a very short time.

Q: The reason why graphite is used as electrode: Graphite is good in plasticity and easier to be machined preciselyGraphite material has the advantages of high processing accuracy and good surface effect, especially in the processing of precise, complex, thin-walled and Gao Ying material mold cavity. Because the cutting resistance of graphite is only 1/5 of copper material, it is easier to do manual grinding and polishing on the operation. There is no burr after graphite processing, and it is easier to realize automatic production. Complex geometric modeling can be realized.

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: 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: How can hydrogen be produced by electrolysis of sodium hydroxide with graphite as an electrode?: You can think so, since sodium has been reduced, so there is always an atom is oxidized, it can only be oxygen oxidation reaction

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: How can the graphite powder be processed into high quality carburizing agent? Thank you: Basically, it can no longer be a "good" carburizing agent

Q: What are the factors that affect the electrode wear rate of machine tools?: Effect of peak pulse current on electrode wear. The peak current has a great influence on electrode wear, but the curves are very different due to the different materials of the electrode and the workpiece. In the copper electrode machining steel, general peak current, electrode loss is also large, but also have a great relationship with the pulse width, so in practice, we should choose different peak current of different area according to the data processing technology of power supply and discharge pulse width, can make the processing speed is high, and the electrode loss small.

Q: After vacuum melting of quartz crucible, there are three graphite electrode rods. What's the adjustment?: The shorter one is the farther away from the other, and the shorter one is the shorter one

Q: How about graphite electrode high-temperature oxidation resistant coating?: Heat resistant coating is generally able to withstand 300 degrees below the temperature, commonly used aluminum heat-resistant paint, high temperature resistance can withstand higher temperatures, such as 800 degrees or more, commonly used silicone heat-resistant paint
