Ultra High Power Graphite Electrode For Sale

As is known to all, graphite electrode as a common consumption material in eaf steelmaking and smelting, is made of petroleum coke, needle coke and coal bitumen as a binder through molding, roasting, dipping, graphenization and mechanical processing. According to its specification and quality index, divided into ordinary power, high power, ultra high power graphite electrode.

This type of graphite electrode is shaped like a cylinder with a thread area at each end. The joint matching the graphite electrode is an accessory of the graphite electrode to complete the assembly of the whole electrode. Dimensions are generally 200-500 mm in diameter and 1700-1900 mm in length.

The ultra high power graphite electrode adopts high-quality needle coke as the main raw material, which is made strictly by crushing, sifting, batching, kneading, pressing, roasting, high-pressure dipping, secondary roasting, graphitization, machining and other processes. The graphitization heat treatment is carried out in the graphitization furnace, and the temperature is up to 2800-3000°C. Therefore, it has lower resistivity and higher current density.

Ultra high power graphite electrode allows current density greater than 25A/ cm 2, mainly used in ultra-high power steelmaking arc furnace. In order to meet the requirements of higher working efficiency and lower total cost, high-capacity ultra-high power arc furnace is more and more popular. So UHP graphite electrodes with a diameter of more than 500 mm will dominate the market.
