Graphitelektroden
Our graphite electrodes for electric arc furnaces and ladle furnaces are made from high quality raw materials like petroleum coke, needle coke and pitch and, after a complex production process, are being precisely machined with CNC-technology according to customer’s requirements. Low resistivity, high bulk density and high mechanical strength are the key properties of our graphite electrodes.
We offer you high quality graphite electrodes from our international and audited producers. Benefit from our excellent technical expertise, longstanding experience and our own quality assurance in this field. We are glad to offer you our technical support as well as our warranties for product properties and even consumption rates.
