SGL Carbon SE products

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.

For more than 50 years, we design and produce graphite heat exchangers for many corrosive applications. Our product lines – the largest of its kind in the industry – include the full range from shell & tube to block or plate heat exchangers. DIABON® graphite makes the heat exchangers suitable for corrosive media on both service and product side and ensures high thermal conductivity.

For the processing of highly abrasive or oxidizing media, free halogens and extremely aggressive solvents, we offer a high end product line of silicon carbide (SiC) heat exchangers. SiC is one of the hardest materials available. Combined with a high thermal conductivity, this feature makes it a perfect choice for the heat exchange under most demanding chemical conditions.

Our special heat exchangers are designed for the recovery of thermal energy from flue gases. Our introduction of corrosion resistant graphite in this segment means a real innovation for the heating industry. It can enhance the overall energy efficiency of combustion processes by more than 10% and at the same time substantially reduce the operating costs of the heating system.
