The using of Graphite Electrode in EAF

With the rapid development of China’s economy, the demand for special steels from all walks of life has become more and more extensive, resulting in the rapid development of electric arc furnace steelmaking technology. Large-capacity ultra-high-power electric arc furnaces and large-scale out-of-furnace refining technologies have become the modern iron and steel industry. Sign. There are 18 domestic roughing electric arc furnaces above 100T, transformer capacity 65~150MV*A; there are about 30 electric arc furnaces 50~100T, transformer capacity 35~85MV*A; there are 126 LF refining furnaces 40~300T, The transformer capacity is 10~45MN*A. These electric furnaces all use different specifications of ultra-high power graphite electrodes. With the continuous improvement of arc power and continuous optimization of smelting technology, the requirements for physical and chemical indicators of graphite electrodes are getting higher and higher and the consumption indicators are getting lower and lower.

From the point of view of the average consumption level of large-scale and large-capacity ultra-high-power electric arc furnaces, the electrode consumption per ton of steel has dropped from an average of 3.5KG/T to 1.2KG/T in the past, while the average consumption of LF furnaces is lower than 0.5KG/T . Because graphite electrodes account for a certain proportion of the cost in smelting and consume a lot of money, all manufacturers attach great importance to the consumption and use effect of graphite electrodes, and they are also included in the production as an important assessment indicator.

Rongxing Group, with 20 years manufacture experience of Graphite Electrode, products has sold to Overseas nearly 30 countries. We are committed to improve the satisfied rate of customers, and strive to add value along the entire value chain of the global steel industry.

Products UHP Graphite Electrode as our advantage product, has win a lot good feedback from final users.
