How to choose graphite electrode for steelmaking electric arc furnace?

Ordinary power electric furnaces use ordinary power graphite electrodes, high-power electric furnaces are equipped with high-power graphite electrodes, and ultra-high power electric furnaces are equipped with ultra-high-power graphite electrodes.

For AC steelmaking electric arc furnaces, 10-30t electric furnaces are equipped with 300-400mm diameter graphite electrodes, and 30-50t electric furnaces are equipped with 450mm diameter graphite electrodes.60-80t electric furnaces are equipped with 500mm diameter graphite electrodes, 100-170t electric furnaces are equipped with 550-600mm diameter graphite electrodes, and 200t electric furnaces are equipped with 600-700mm diameter graphite electrodes.The 250-300t electric furnace is equipped with a 700mm diameter graphite electrode.

For the DC steelmaking electric arc furnace, the 30t electric furnace is equipped with 450mm diameter graphite electrodes, the 60t electric furnace is equipped with 500mm diameter graphite electrodes, and the 70-80t electric furnace is equipped with 600mm diameter graphite electrodes.The 100-130t electric furnace is equipped with a 700mm diameter graphite electrode, and the 150t electric furnace is equipped with a 750mm diameter graphite electrode.
