Annealing Furnace
AssemblyHeats the strip in a sealed reducing atmosphere of hydrogen and nitrogen, recrystallizing the steel and reducing surface oxides so the zinc bonds. The strip leaves through a sealed snout straight into the molten zinc without re-oxidizing. A full specification article for this item is being written. Meanwhile its bill of materials and connections are below.
