Abstract
1394198 Continuous heat treatment furnaces ALLEGHENY LUDLUM INDUSTRIES Inc 15 Sept 1972 [17 Sept 1971] 27139/74 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 positioning a coil in vestibule means at the entrance end of an elongated furnace, sealing said vestibule means and purging the same of gaseous contaminants, thereafter transferring the coil from the vestibule means to the furnace and moving said coil from the entrance end of the furnace through successive heating and cooling zones of the furnace while circulating through said furnace a non-oxidizing gas, and finally removing the coil from the exit end of said furnace, said coil being heated within an initial furnace section and after it has been transferred into the furnace from the vestibule means while the space around the coil is evacuated before the coil is subjected to said non-oxidizing gas within the furnace, whereby water of hydration will be removed from the surfaces of said strip material.
