The most critical factor in the development of graphite electrodes is the grade of petroleum coke used, as higher grades of the petroleum coke produce higher quality electrodes. In addition to the grade of petroleum coke, several other factors can impact the quality of the HP graphite electrode and its ability to carry a current such as length, diameter, bulk density, resistance and porosity. For example, lower grades of coke do not allow for an electric current to pass through as easily. There are two different types of graphite electrodes available. One type is called “SDGE,” which stands for small diameter High power graphite electrodes . These electrodes are most commonly used for melting scrap metal and other refractory raw materials and are used in Electric Arc Furnaces (EAF). These electrodes carry a current that creates an arc between the electrode and the refractory raw material, causing it to melt. The other electrode type is the “LDGE” or large diameter HP...

★ Overseas HP Graphite electrode production capacity is dwindling. Not only did China's graphite electrode market took a severe hit in recent years, overseas graphite electrode enterprises were also confronted with harsh environment in operationand decline in production capacity. For instance, SGL Group shut down plants inItaly, Spain and Canada, and signed an sales agreement with Showa in November2016. However, global steel output didn't show substantial drop in recentyears. In 2016, global crude steel output is 1.6285 billion tons, up 0.8% froma year earlier. Across the globe, regions that registered growth in crude steeloutput include Europe, America and Africa; those recorded decline include CIS,the Middle East, Asia and Oceania. Overseas HP graphite electrode market will facesupply shortages as well. In this context, ICCNews has reached out to and gathered information from major graphite electrode manufactures at home and abroad. ★ One manager from...

They are presently the only products available that have the high levels of electrical conductivity and the capability of sustaining the extremely high levels of heat generated in this demanding environment. Graphite electrodes are also used to refine steel in ladle furnaces and in other smelting processes. GrafTech International introduced UCAR Grade AGX ultra-high power (UHP) graphite electrodes and Grade AGX supersize graphite electrodes, 700 to 750 mm in diameter. Now GrafTech International offers unique Grade ALX pinless graphite electrodes to address the issues of stub losses and poor bottom joint performance, Grade LFX premium quality electrodes designed and engineered specifically for the ladle furnaces and non-steel applications. Graphite electrodes are also used to refine steel in ladle furnaces and in other smelting processes. The HP graphite electrodes carry the el...

Graphite electrode market finally starts to pick up this spring after nearly two sluggish years. Pricesof HP graphite electrode products have been raised across the board, with HP products registering an increase of 3000 yuan/mt and UHP products 5000 yuan/mt.This round of price increase is contributed by multiple factors. Specifically, ★ Prices of refractory raw materials have been soaring,with an increase of over 80% generally. According toinformation compiled by ICC News, up to now, domestic low-sulphur petroleumcoke prices have increased to 2000 yuan/mt from last November's November; coalpitch prices have risen to 3,300 yuan/mt from last October's less than 2,000yuan/mt. Domestic needle coke prices have now risen to 5,800 yuan/mt from theprevious 3,200 yuan/mt as well. The increase in cost in real terms is a factbeyond doubt. ★ Supply and demandwas out of balance at the previous stage. Amid prolongedrecession of domestic steel market in recent yea...

1. Diverse mold geometry are complicated and product application requirements for the accuracy of EDM discharge leads to more and more high. The advantages of the graphite electrode is easy processing, high removal rate of graphite EDM, small loss, therefore, some group based spark machine spark machine customers give up copper electrode instead of graphite electrode . In addition, some electrode the special shape of the cannot be made of copper, but the graphite is easily molded, and the copper electrode is heavy, not suitable for processing large electrode, these factors have caused some group based spark machine spark machine application of graphite electrode. 2. HP Graphite electrode is easy to processing, and the processing speed is obviously faster than the copper electrode. For example, the milling of graphite, the processing speed is 2~3 times faster than other metal processing and does not require additional manual processing, and the copper electrode needed...
