Title:
MOLTEN METAL BATH COMPONENT ANALYSIS SYSTEM, MOLTEN METAL BATH COMPONENT ANALYSIS METHOD, HOT DIP GALVANIZING BATH MANAGEMENT METHOD, AND HOT DIP GALVANIZED STEEL SHEET MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2023/249048
Kind Code:
A1
Abstract:
This component analysis system for a molten metal bath is provided with: a laser oscillator for emitting a laser beam; a tubular probe an open end of which is immersed in a molten metal bath, which supplies inert gas toward the open end, and which optically guides the laser beam to the open end to irradiate the molten metal; and a detection unit for detecting plasma emission from the molten metal produced by the laser beam irradiation and performing spectral analysis. The position of the open end of the tubular probe in the molten metal bath and/or the angle of the tubular probe with respect to the perpendicular direction is configured to be controllable.
