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: Why is graphite conductive electrode oxidized?: The reason for its oxidation is that it is oxidized at atmospheric temperature by reacting with the oxygen in the air

Q: What are the factors affecting the service life of graphite electrode in ultra high power arc furnace?: China's graphite electrode quality standard (YB/T4090-2000) to evaluate the quality of the ultra high power graphite electrode is defined 6 physicochemical indexes, including resistivity, flexural strength, elastic modulus, bulk density and linear expansion coefficient as the quality evaluation index, ash as a reference index.

Q: Why graphite can be used as conductive material?: Lubricants can not be used in high speed, high temperature, high pressure conditions, and graphite wear-resistant materials can be at the temperature and at a high sliding speed, without lubricating oil work. Many transporting corrosive media devices are widely used, which is made of graphite material piston ring, the sealing ring and the bearing, they are running, without adding lubricating oil, graphite and many metal processing when good lubricant.

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: Does the silicon carbide heat plant require a fine structure graphite electrode? What kind of graphite products do you need?: Silicon carbide graphite is very famous for its high hardness and wear resistance. It is generally used in high wear resistance machinery industry and high wear resistant sealing industry.

Q: What is the graphite furnace electrode with a diameter of 400?: 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: Which department in the steel plant needs graphite in large quantities?: Steelmaking department. The graphite electrode steelmaking is to enter the electric energy through the graphite electrode to the electric arc furnace, and takes the arc between the electrode end and the furnace charge as the heat source to carry on the steel smelting. The electric arc furnace takes electric energy as heat source, and can adjust the atmosphere in the furnace. It is very beneficial to smelt the steel which contains more easily oxidized elements. Smelting a variety of alloys

Q: The production of one ton of steel required graphite electrode: Not sure, look at your such as what is charge, and your smelting level.If the proportion of molten iron to the furnace is high, then the electrode consumption is low, 0.7kg/t, or lower. If it's cold, 1-2kg/t.

Q: How should carbon deposits be treated?: It is very necessary to clean the throttle valve, clean the nozzle, and clean the carbon in the engine cylinder! However, in order to reduce the trouble of cleaning, it is best to join the regular application of graphene Moqi additive in lubricating oil for engine.

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
