Interesting that sometime in late 1908 the Societe Cockerill in Seraing was going to install an electric/Girod furnace or something like a Hroult furnace. But Qualittsstahl and Spezialstahl are recipes that are associated with a Rchling - Roderhauser furnace. Also in 1908 a Rchling - Roderhauser furnace is to be installed in Liege at the Societe des Alieries. This makes me wonder if the tubes were rolled there?

Kind Regards,
