Furnace Lining, test assembly tuyères

SGL Group sells off its cathodes, furnace linings, and carbon electrodes business.

As of November 2nd, 2017, SGL CFL CE GmbH and its subsidiaries (referred to collectively here as “CFL CE“) are no longer part of the SGL Carbon SE Group but independent companies. Until CFL CE creates its own website, information on CFL CE and its products will continue to be displayed here temporarily at the sole responsibility of CFL CE. SGL Carbon SE and its affiliated companies therefore assume no liability for the contents and statements appearing here.

SGL Group sold its cathodes, furnace linings, and carbon electrodes (CFL CE) business to funds advised by Triton.

Furnace Linings

The Blast Furnace/Blast 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. The improvement of material and design solutions has significantly increased the productivity and campaign life of Blast Furnaces since then. We`ve been an expert partner to the steel industry since the beginning. We are 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. The state-of-the-art provides machining with the tightest tolerances. Several assembly plates shorten lead-times and reduce the number of inspections.
