Abstract
1394199 Heat treating metal strip ALLEGHENY LUDLUM INDUSTRIES Inc 15 Sept 1972 [17 Sept 1971] 27140/74 Divided out of 1394197 Heading F4B [Also in Division C7] The subject-matter of this Specification is substantially the same as that disclosed in Specification 1,394,197, but the claims are concerned with a method for heat treating strip material in coil form which comprises moving said coil through successive heating and cooling zones of a furnace while circulating through the furnace a non-oxidizing gas, said coil being initially heated in an evacuated chamber prior to its passage through said furnace containing the non-oxidizing atmosphere to remove from the surfaces of said coil any water vapour.
