鋼板の焼鈍装置、これを含むメッキ鋼板の製造装置及びそれを用いたメッキ鋼板の製造方法
Document Type and Number:
Japanese Patent JP2012514131
Kind Code:
A
Abstract:
Provided is a method for producing plated steel sheet by means of an annealing device which includes at least one section and in which the at least one section is filled with a gas constituting a non-reducing atmosphere or a weakly reducing atmosphere to substantially improve the quality of plating onto hot-dipped steel sheet, including the plating properties, alloying properties, anti-pickup properties, plating adhesion properties, anti-flaking properties, anti-cratering properties and anti-ash properties, by using prior-art annealing equipment and heat-treatment cycle without any additional oxidation-reduction heat treatment process or large quantities of high-cost alloying elements.
