The process of defect detection and defect detection system of superfu00eccie

摘要

"The process of defect detection and defect detection system of superfu00eccie".The present invention relates to a process for detection of surface defects of a product raw metal continuous casting, such as a steel plate (4),Being carried out by means of a sensor (10) for surface defects by eddy currents, which comprises a sensor array that has at least two rows (22.24) of at least three cells to measure (21) each adjacent to and can be controlled by a control unit (12) with multiplexer.Each cell is able to generate eddy currents in the surface of the plate of rectangular section and, in an alternative way to detect eddy currents in the same area.And a process which includes a step of commanding a first cell network and a second receiving cell of the same row separated from one another by at least one cell inactive.
