Title:
PLATING ADHESION EVALUATION DEVICE, PLATING ADHESION EVALUATION METHOD, EQUIPMENT FOR MANUFACTURING ALLOYED HOT-DIP GALVANIZED STEEL SHEET, AND METHOD FOR MANUFACTURING ALLOYED HOT-DIP GALVANIZED STEEL SHEET
Document Type and Number:
WIPO Patent Application WO/2019/069832
Kind Code:
A1
Abstract:
Provided are a plating adhesion evaluation device, a plating adhesion evaluation method, equipment for manufacturing an alloyed hot-dip galvanized steel sheet, and a method for manufacturing an alloyed hot-dip galvanized sheet, with which it is possible to more accurately measure the quantity of a Γ·Γ single phase and to more accurately evaluate the plating adhesion of an alloyed hot-dip galvanized steel sheet. [Problem] A plating adhesion evaluation device according to the present invention comprises: an X-ray diffraction intensity measurement unit that measures the intensity of X-ray diffraction of a Γ·Γ single phase through an X-ray diffraction method with respect to an alloyed hot-dip galvanized steel sheet; and an evaluation unit that, on the basis of the X-ray diffraction intensity of the Γ·Γ single phase and the galvanization weight, evaluates the plating adhesion of the alloyed hot-dip galvanized steel sheet.
