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 connecting pins as standalone 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 consumption in the steel plants.

The Blast FurnaceBlast Oxygen Furnace route was developed for the production of high quality primary steel. It is the most successful route to produce primary steel. As the availability of scrap metal and electricity increases, the number of EAF (Electric Arc Furnaces) will increase to recycle the scrap. The EAF steel will not be sufficient to cover the steel demand in the world, and both production routes have a bright future.In the beginning of the 60ies, the refractory lining of the lower part up to the middle stack of blast furnaces was turned successfully to carbon and graphite materials. SGL Group actively pushed this development. The improvement of material and design solutions has significantly increased the productivity and campaign life of Blast Furnaces since then. SGL Group has been an expert partner to the steel industry since the beginning. SGL Group is able to meet all specific requirements for Blast Furnaces due to the most comprehensive product range of the Furnace Linings Industry. The range consists of carbon and graphite grades including supermicroporous carbons and microporous ceramic carbons, glues and cements to cater to the specific needs of the different areas in the Blast Furnace or Submerged Arc (Reduction) Furnace. Intensive development work ensures continued best solutions for the future. SGL Group provides state-of-the-art machining with the tightest tolerances. Several assembly plates shorten lead-times and reduce the number of inspections.
