• 1969:  The Paul Wurth engineers invent a revolutionary new blast furnace charging system: the Bell Less Top^® . Herewith Paul Wurth holds a patent which is of interest to iron & steelmakers the world over.

Towards an international engineering company

• 1977:  Société Anonyme des Anciens Etablissements Paul Wurth becomes Paul Wurth S.A. From this time on Paul Wurth becomes an international market leader to the ironmaking industry. It creates subsidiaries and branches, first in Brazil in 1977, followed by Canada and the U.S. Today the Group has offices in all main steelmaking regions of the world.

• 2000:  Development of the PRIMUS^®  technology for recycling steelmaking residues: Pilot plant at ProfilArbed in Esch-Belval (2000); Industrial plants at ArcelorMittal Woiwer in Luxembourg/Differdange (2003) and at Dragon Steel Corporation in Taiwan (2009).

• 2003:  Paul Wurth creates together with Dango & Dienenthal Maschinenbau GmbH the joint company TMT Tapping Measuring Technology specialised in the blast furnace tapping and measuring technologies.

• 2004:  Paul Wurth transfers its fabrication activities within the Arcelor Group to MecanArbed Dommeldange, now ArcelorMittal Dommeldange, and is now a pure engineering company.

• 2004:  Paul Wurth acquires the German engineering company Didier - M&P Energietechnik GmbH, specialized in the field of hot blast stove technologies and refractory and lining concepts for blast furnaces. As from 2006, the legal name of the company changes to Paul Wurth Refractory & Engineering GmbH.

• 2005:  Paul Wurth S.A. takes over the blast furnace, coke making and direct reduction activities as well as the staff from SMS Demag S.p.A. in Genoa, Italy. For this purpose, Paul Wurth Italia S.p.A. is created.

• 2009:  Paul Wurth S.A. takes a 50.4% shareholding in CTI Systems S.A., a company specialized in the design and manufacture of automated systems for the lifting and handling of heavy goods and ensures thereby the enlargement of its business segments.
