Graphite electrodes are important components in electric arc furnace steelmaking and other industrial and civil fields. They are made of high-purity graphite materials, have excellent conductivity and high-temperature stability, and can withstand high-intensity current and high-temperature environments. ZhenAn produces two major components that make up a complete graphite electrode: the graphite electrode body and the joint.
The ultra-high power graphite electrode produced by ZhenAn is an indispensable conductor and thermal conductive material in green steelmaking in electric arc furnaces. It surpasses blast furnace steelmaking in terms of environmental protection and energy saving, and represents the main direction of energy conservation and emission reduction in the global steel industry.
Graphite electrodes have a long history of more than 100 years. Graphite is a unique material in the steelmaking process and there is currently no known substitute.
Graphite has the characteristics of high temperature resistance, high thermal conductivity, low resistance, and high high temperature strength.
