HIGH QUALITY GRAPHITE ELECTRODE PRODUCTS
GrafTech International is a leading manufacturer of high quality graphite electrode products essential to the production of Electric Arc Furnace (or EAF) steel and other ferrous and non-ferrous metals.
We have a broad portfolio of competitive graphite electrode manufacturing facilities, including three of the highest capacity facilities in the world. We are the only large scale graphite electrode producer that is substantially vertically integrated into petroleum needle coke, a key raw material for graphite electrode manufacturing. This unique position provides competitive advantages in product quality and cost.
MAXIMIZING STEEL PRODUCTIVITY THROUGH TECHNOLOGY AND SERVICE LEADERSHIP
Founded in 1886, we have over 130 years of experience in the research and development (or R&D) of graphite and carbon based solutions, and our intellectual property portfolio is extensive. We currently have graphite electrode manufacturing facilities in Calais, France, Pamplona, Spain, Monterrey, Mexico and St. Marys, Pennsylvania. Our customers include major steel producers and other ferrous and non ferrous metal producers in Europe, the Middle East and Africa (or EMEA), the Americas and Asia Pacific (or APAC), which sell their products into the automotive, construction, appliance, machinery, equipment and transportation industries.
Our vision is to provide highly engineered graphite electrode services, solutions and products to EAF operators. Based on the high quality of our graphite electrodes, reliability of our petroleum needle coke supply and our excellent customer service, we believe that we are viewed as a preferred supplier by the global EAF steel producer market.
GRAFTECH SERVICE AND SOLUTIONS
We consider sustained customer satisfaction as a key measure of product and service performance. GrafTech International’s stringent quality system focuses on the customer’s needs and satisfaction.
• Substantial vertical integration into petroleum needle coke provides a secure source of raw material supply and associated quality control, along with a sustainable competitive advantage.
• Four manufacturing facilities in different continents ensure a global footprint and a reliable graphite electrode supply in each region.
• Statistical process control used in our manufacturing process and over 130 years of experience in the graphite industry lead to the production of superior and reliable quality electrodes.
• Customer Technical Service multi-disciplinary engineers with extensive know-how in the steel and electrode industry provide consultative services and solutions in furnace operations and efficiency.
• Global experienced sales team located around the world provides continuous support and advice to customer specific needs in over 65 countries.
• A strategically located network of distributors ensure a reliable graphite electrode supply.
• With the support of ArchiTech™ Furnace Productivity System, our engineers can follow key furnace operations data and help EAF operators optimize operations.
UCAR® Grade AGX™ Graphite ElectrodesA premium grade that we recommend for AC high-power, ultra-high-power and DC furnaces operating under severe electrical or mechanical conditions.
UCAR® Grade LFX™ Graphite ElectrodesLadle furnaces have different operating parameters than melting furnaces. We recommend this premium grade for those furnaces and other low-power melting applications.
CHOOSING THE RIGHT ELECTRODE
Our technical experts can help you select the right UCAR® graphite electrode by assessing the specifics of your operating environment.
• Burner and oxygen usage• Conversion costs• Electrode consumption goals• Electrode strength and oxidation• Fume control system
• Furnace design• Power level and power input
program• Productivity goal• Refractory consumption goal
• Scrap types/charging practice• Slag practice• Steel type and grade• Tap-to-tap time• Water spray rings
