Graphite Electrodes | Tokai Carbon Co., Ltd.
The diameter of these electrodes is getting bigger: the current maximum diameter is 32 inches (800 mm). For AC Furnaces (alternating current furnaces) / Size: 16-28 inches. Alternating current furnaces require 3 columns of graphite electrodes. They mostly use 20-28 inch electrodes, the standard size in electric furnaces.

Graphite Electrodes. Graphite electrodes are used mainly in the production/recycling of steel, where steel scrap is melted in a large furnace by the heat from an electric arc, hence ‘electric arc furnaces’. Approximately 1/3 of global steel is produced in this way, making it the largest recycling process in the world.
