Our company
Hengtai Group, one of the leading enterprises in China Carbon Industry, has been specializing in technology research and development, manufacturing and sales of graphite electrodes, carbon additive and other carbon products. Graphite electrodes are widely used in electric arc furnace and ladle furnace for steel production, ferroalloy production, silicon metal production and smelting processes. In addition to high temperature which can reach up to 3000, our graphite electrodes are featured with lower electric resistance, lower ash content, lower coefficient of thermal expansion, higher transverse strength, higher elastic modulus and higher bulk density.
