摘要： PROBLEM TO BE SOLVED: To provide a method for stably and relatively easily manufacturing a galvanized steel sheet superior in press formability, and an apparatus therefor.
SOLUTION: This manufacturing method has a step of adjusting a surface morphology of the galvanized steel sheet, by spouting a liquid jet into a liquid in the vicinity of the surface of the galvanized steel sheet to cause cavitation thereon, and by causing plastic deformation on the surface of the galvanized steel sheet by impulsive force produced when cavitation bubbles collapse. The step of adjusting the surface morphology adjusts one or more of an average roughness Ra of the surface of the steel sheet, a peak count PPI of the surface of the steel sheet, and a filtered-wave center line waviness Wca of the surface of the steel sheet, through adjusting conditions of the cavitation. The manufacturing method is suitable for adjusting the surface morphology of particularly a non-annealed galvanized steel sheet having a plated film comprising mainly a η-phase.
