Graphite electrodes are used for the recycling of steel in the electric arc furnace industry, so called “mini-mills”. They are also used in the refining of steel as well as in the non ferrous industries, where smelting processes are in use.
Graphite Electrode
ite Electrode for Scrap Steel Meltingngda graphite electrode
As we know, there are two ways to make iron. The blast furnace method and the electric arc furnace method. Graphite electrodes are widely used in electric arc furnace (EAF) and ladle furnace (LF) for steel production. It is the graphite electrodes inside the furnace that actually melt the iron. Graphite has high thermal conductivity and is very resistant to heat and impact. It also has low electrical resistance, which means it can conduct the large electrical currents needed to melt iron.
Graphite Electrodes Grades:
• Ultra-high power (UHP) electrode
• High power (HP) electroe
• Regular power (RP) electrode
Graphite Electrode For DC Furnaces(direct current furnaces)/ Size: 22-32 inches
DC electric arc furnaces requires 1 column of graphite electrodes and high maximum current density.
The diameter of these electrodes is getting bigger: the current maximum diameter is 32 inches (800 mm).
Graphite Electrodes For AC EAF Furnaces (alternating current furnaces) / Size: 16-28 inches.
Alternating current EAF requires 3 columns of graphite electrodes. They mostly use 20-28 inch electrodes, the standard size in electric furnaces.
For LF Furnaces (refining furnaces) / Size: 10-18 inches
These electrodes are for refining materials like molten steel. LF Furnaces have a smaller capacity than DC
