Abstract
X-ray Fluorescence analysis sytem using Si (Li) non-dispersive detector is developed and it can be applied to steel industrial analysis. The system is especially suitable to the on-line rapid analysis as the Si (Li) detector has very high sensitivity and is not affected by circumstance. The applicatinos of the system are as follows.
(1) On-line X-ray fluorescence analysis of tubings in order to distinguish the type of steel.
(2) X-ray fluorescence analysis of particular shape objects, such as wire cross-section, large forged steel etc.
(3) Thickness measurement of coating on steel sheet zinc coating thickness for galvanized sheet and paint thickness of colored galvanized sheet.
(4) X-ray diffraction
The results are very excellent, resolution power and stability are practically satisfied.
