Description of Hollow Graphite Electrode

Rongxing Hollow Graphite Electrode products have strict consumption control, low resistivity, low ash content, high temperature strength, low thermal expansion coefficient, good thermal conductivity and electrical conductivity, compact structure, high oxidation resistance, high mechanical stability and other significant advantages. Its content of UHP needle coke is up to 80%. The UHP Hollow Graphite Electrode suit the operating conditions of modern arc furnaces and those main properties are of decisive importance for obtaining economical consumption rates.

Rongxing has a group of experts in the field of servicing Hollow Graphite Electrode. All of our technicians are trained engineers that have worked in furnaces or within Hollow Graphite Electrode manufacturers in the past. We know all of the EAF, Ladle, and Foundry applications throughout China and the world. Our experienced engineers offer an all-round support to the customers for taking our UHP electrodes into operation.They check and analyse the customers’ furnace conditions in order to achieve an optimal performance of the Hollow Graphite Electrode and a decrease of the specific electrode consumption. Beyond the standard procedure of selling electrodes, such as signing contracts, providing third-party testing and regular after-sales service, we support customer in many ways. This includes signing warranty agreement, ensuring the product using effect, identifying a problem before it happens and solving the problem to relieve customers of worries.
