发明名称 STEEL SHEET ANNEALING DEVICE, DEVICE FOR PRODUCING PLATED STEEL SHEET COMPRISING THE SAME, AND PRODUCTION METHOD FOR PLATED STEEL SHEET USING THE SAME
摘要 Provided is an annealing device which comprises 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, as well as a device for producing plated steel sheet comprising the annealing device, and a method for producing plated steel sheet by means of such a device 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.
