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, Raimey- as an amateur student of metallurgy, do you know what the chemical compositions of Quality Steels and then the Rochling Special Steels are, and perhaps how they differ. Just a SWAG, but it makes sense to me that they were indeed, roll formed there in Liege- but of course, I am neither a "Frenchy or a Belgie" so perhaps, Machts nicht, Ja!!
