High Power Graphite Electrode 600mm

Ultra-High Power Graphite Electrode 600mm Description

According to the classification of electric furnace steelmaking power levels, the different raw materials used in the production of graphite electrodes, and the different physical and chemical indicators of the finished products, graphite electrodes are divided into three types: ordinary power graphite electrodes (RP), high power graphite electrodes (HP) and ultra-high power graphite electrodes (UHP).
The development of electric furnace steelmaking technology (larger, single-unit capacity electric furnaces and DC electric arc furnaces) has continuously raised new requirements for graphite electrode varieties and performance. High-power and ultra-high-power electric furnace steelmaking can shorten furnace charging time, improve production efficiency, reduce power consumption, and minimize graphite electrode consumption.

Ultra-high power 600mm graphite electrodes are produced using high-quality needle coke and undergo gravity heat treatment in an inline graphitization furnace. The graphitization temperature reaches 2800-3000°C, resulting in low resistivity, allowing for high current densities, a low linear expansion coefficient, and excellent thermal shock resistance.

The quality of the joints in ultra-high power 600mm graphite electrodes is particularly important. The resistivity and linear expansion coefficient of the joint blank must be slightly different from those of the electrode blank, and the joint quality must be superior to that of the electrode blank.
