Extract

The industrial use of X-ray fluorescence (XRF) coating gauges is a well established practice. For homogeneous coatings such as zinc or tin on steel, on-line XRF gauges are in use around the world. In continuous coating lines coils of uncoated metal are welded to one another and are coated at speeds between 100 and 2000 ft/min. Gauges are used to read cross-sheet coating profiles and determine the average coating thickness through the length of the coil. The motivation for the use of these on-line X-ray instruments is quality control, particularly coating uniformity, and raw materials savings.
