MANUFACTURING METHOD OF A HIGH MANGANESE LECTURE MOLTEN GALVANIZING STEEL PLATE WITH A SUPERIOR PLATING SURFACE QUALITY

摘要

PURPOSE: A manufacturing method of a high manganese lecture molten galvanizing steel plate with a superior plating surface quality is provided to prevent the floating dross of Fe-Al by preventing the running of a plating layer by making the content of aluminum in 0.25%.;CONSTITUTION: A manufacturing method of a high manganese lecture molten galvanizing steel plate with a superior plating surface quality comprises: a step of performing the oxidization of a high-manganese steel in order to form a porosity surface by controlling a heating time and a heating temperature of ambient gas; a step of reducing a high-manganese steel in a reducing atmosphere; and a step of performing a melting zinc coating with the reduced high-manganese steel.;COPYRIGHT KIPO 2010
