Germany, Riesa: German rebar mill Feralpi Stahl is to invest in its own power substation at the premises in Riesa, Saxony.

The German subsidiary of Italy’s Feralpi Group, formerly known as Elektro-Stahlwerke (ESW) Riesa, has lined up some $187 M (€180 M) for improvement of equipment and logistics. This will include a new rolling mill, improvements in scrap handling and on-site logistics, and the power substation. Site clearance for the construction will start immediately, the company says.

The mill will be partnering with Siemens Energy as technology provider, and points out a major source of emissions which it aims to avoid in future.

Until now, sulphur hexafluoride, or SF6 for short, was used in gas-insulated switchgear (GIS), which is prone to escape through the smallest leakages. “These have a greater impact on the greenhouse effect than domestic air traffic,” says Henning Hamann, head of technical projects.

SF6 is the strongest known greenhouse gas, Hamman explains, where 100 g of the gas has the same effect as 2.5 T of CO2, and it also breaks down extremely slowly in the atmosphere, with a residence time of over 3,000 years, 25 times as long as CO2. The new type of switchgear at Feralpi Stahl will work with “clean air” made up of natural gases nitrogen and oxygen.
