Title:
ON-LINE PLATING ADHESION DETERMINATION DEVICE FOR GALVANNEALED STEEL SHEET AND GALVANNEALED STEEL SHEET PRODUCTION LINE
Document Type and Number:
WIPO Patent Application WO/2015/059835
Kind Code:
A1
Abstract:
This on-line plating adhesion determination device for a galvannealed steel sheet is provided with an X-ray tube for irradiating X-rays toward a galvannealed steel sheet traveling on a conveyor line, an optical system for irradiating the X-rays emitted from the X-ray tube onto the galvannealed steel sheet as a parallel beam and causing the X-rays to be diffracted, and a detector that is for measuring the intensity of the diffracted X-rays and is disposed in a position for detecting diffracted X-rays corresponding to a crystal lattice spacing (d) of 1.5 Å or more. The emitted beam irradiance of the X-rays is made to be at least 20 W/mm2. The X-ray width direction gain in the optical system is made to be at least 0.15. The crystal lattice spacing (d) may be 1.914 Å. Additionally, the incident X-ray energy from the X-ray tube may be less than the X-ray fluorescence excitation energy of Fe-Kα.
