| 摘要 |
<p>The present invention relates to an installation for in-line controlling and, in real time, a bath for the hot-dip coating of a metal sheet by means of a molten metal, in particular for controlling the chemical composition of the bath and the presence of dross on the surface of the bath, comprising an LIBS (laser-induced breakdown spectroscopy) analysis system, a device for directing the laser beam onto the region to be analysed, a camera associated with a light source, so as to acquire an image of the bath at a point that it is desired to monitor the presence of dross, a control system, incorporated into a computer, for carrying out image processing, the storage of chemical analysis data using the aforementioned LIBS method, and the management of the movements of the laser beam and a system for warning an operator or a robotic mechanical device for removing dross from the surface of the bath.</p> |
