What are the advantages of china manufacturers supplier rp graphite electrodes compared with copper electrodes
1. No burr: After the copper electrode is processed, the burr needs to be manually removed, and there is no burr after the graphite is processed, which not only saves a lot of cost and manpower, but also makes it easier to realize automated production.
2. Low cost: Due to the continuous increase in copper prices in recent years, the price of homogenous graphite in all aspects is lower than that of copper, the price is relatively stable, and short-term price fluctuations are relatively small.
3. Fast speed: Graphite discharge is 2-3 times faster than copper, and the material is not easy to deform. It has obvious advantages in the processing of thin rib electrodes, but copper electrodes are easy to deform.
4. Light weight: The density of graphite is only 1/5 of that of copper. When large electrodes are used for electrical discharge machining, it can effectively reduce the burden on the machine tool (EDM).

china manufacturers supplier rp graphite electrodes and needle coke
The production process of carbon materials is a strictly controlled system engineering. The production of china manufacturers supplier rp graphite electrodes, special carbon materials, aluminum carbon materials, new high-end carbon materials, etc. are inseparable from the four production elements of materials, equipment, skills, and management. Combine the application with related proprietary skills.
The material is the key element that determines the fundamental characteristics of the carbon data, and the function of the material determines the use function of the produced carbon data. As far as the production of UHP and HP china supplier rp graphite electrodes is concerned, high-quality needle coke is the first choice, as well as high-quality binder pitch and impregnant pitch. But only with high-quality materials, lack of equipment, skills, management elements and related proprietary skills, it is also impossible to produce high-quality china manufacturers supplier rp graphite electrodes.
This article focuses on explaining some personal ideas about some characteristics of high-quality needle coke for discussion and discussion with colleagues from needle coke manufacturers, electrode manufacturers, and scientific research institutes.
Although the industrialized production of needle coke in my country is later than that of foreign companies, it has developed rapidly in recent years and has now begun to take shape. In terms of total output, it can basically meet the production of domestic carbon companies. China manufacturers supplier rp graphite electrodes Quantity demand. However, there is still a certain gap in the quality of needle coke compared with foreign companies. The fluctuation of batch function affects the production standard of China manufacturers supplier rp graphite electrodes for high-quality needle coke, especially now that it has not yet been able to meet the requirements of China manufacturers. The supplier rp graphite electrodes connector produces high-quality connector needle coke used in the production.
Foreign carbon companies produce large-standard china manufacturers supplier rp graphite electrodes, and often prefer high-quality petroleum needle coke as the main raw material coke. Japanese carbon companies also use some coal-based needle coke as raw materials, but only for china manufacturers supplier rp graphite with standards below Φ Produced by electrodes. my country’s needle coke is now mainly coal-based needle coke. The high-quality large-standard UHP china manufacturers supplier rp graphite electrodes produced by various carbon companies often rely on imported petroleum-based needle coke, especially the production of high-quality joints. Japan’s Mizushima oil-based needle coke and the British HSP oil-based needle coke are raw coke.
Now the needle coke produced by various companies is generally compared with the commercial function indexes of foreign needle coke based on conventional functional indicators, such as ash content, true density, sulfur content, nitrogen content, particle size distribution, and thermal expansion coefficient. However, in the needle coke grading, compared with foreign countries, there is still a lack of needle coke grading with different levels of functions. Therefore, most of the needle coke produced is generally “all goods”, which does not reflect the graded high-quality and competitive needle coke.
In the comparison of needle coke function, in addition to the conventional function comparison, carbon companies should also pay attention to the classification of needle coke’s coefficient of thermal expansion (CTE), particle strength, degree of anisotropy, non-compression condition and suppression condition. Characterization of the characteristics of needle coke, such as the expansion data, and the temperature range during expansion and contraction. Because these thermal functions of needle coke are very important for the control of the graphitization process in the production process of china manufacturers supplier rp graphite electrodes, of course, the influence of the thermal function of pitch coke formed by the firing of binder and impregnant pitch is not ruled out.
