ABSTRACT:
Disclosed is a combined continuous plating apparatus for hot-dip plating and vacuum deposition plating characterized in that the outlet of the gas reduction annealing furnace of a conventional continuous hot-dip plating apparatus and the inlet of the seal roll chamber of a known continuous vacuum deposition plating apparatus are connected through a pressurized chamber in order to prevent invasion of hydrogen-containing reduction gas into the vacuum deposition chamber, whereby is prevented the possibility of the hydrogen-containing gas causing an explosion should air leak into the vacuum deposition chamber.
