Rongxin Graphite Electrode Introduction:

UHP Carbon Graphite Electrodes Good Price With 20 Years' Experience.

The Graphite Electrode is made of petroleum coke, Needle Coke, coal tar pitch, and the like. It is used as a conductive material in steel mills in the electric arc furnace industry. Rongxin carbon Graphite Electrodes are divided into three different types according to the current load: RP Graphite Electrode, HPGraphite Electrode and UHPGraphite Electrode. We can supply GE in various specifications for different electric arc furnaces, such as DC furnaces, AC furnaces and LF furnaces.UHPGraphite Electrodes from Rongxing suit the operating conditions of modern arc furnaces by high mechanical stability, excellent thermal conductivity, low electrical resistance, factors which are of decisive importance for obtaining economical consumption rates.

Manufacturing Process: 

Rongxin Graphite Electrode is mainly made of petroleum coke and Needle Coke, and the coal bitumen is used as a binder. It is made by calcination, compounding, kneading, pressing, roasting, graphitization and machining. It is to discharge electric energy in the form of electric arc in the electric arc furnace. The conductor that heats and melts the charge can be divided into a common power Graphite Electrode, a high power Graphite Electrode and an ultra high power Graphite Electrode according to its quality index.

 

Application of Graphite Electrodes:

Graphite Electrode is the imperative consumption materials as a electric conductor. It can be used in the industries including producing steel , corundum, phosphorus, and industrial silicon. 

 

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 Graphite Electrodes and a decrease of the specific electrode consumption.

Customers will be asked to provide electric arc furnace parameters and specifications and sizes of electrode, and complete Electrode and Furnace Data Form. This information will be carefully reviewed and used to determine the appropriate grade of electrode.
