Our graphite electrodes are with low resistance, high density, compact structure, anti-oxidation and precise processing, then they are the best conductive material for EAF and LF.
Graphite electrodes are used for the recycling of steel in the electric arc furnace industry, so called "mini-mills." We do not simply provide graphite electrodes and nipples as stand alone products to our customers. Rather, the focus is on the delivery of an entire "product system", supported by sales and technical experts from the receipt of the customer's order, throughout the entire production process, to final product in the steel plants.
