Abstract

A pre-coated plate of steel is heated in a furnace to form an intermetallic alloying layer on the plate at least in an area thereof. Air is pretreated through drying to produce dried air which is fed into the furnace to control the atmosphere within the furnace while the pre-coated plate is in the furnace.
