EDDY CURRENT FLAW DETECTOR AND BAR STEEL ROLLING LINE WITH EDDY CURRENT FLAW DETECTOR

摘要

PROBLEM TO BE SOLVED: To shorten centering operation time and to also easily make a lift off amount proper.;SOLUTION: In an eddy current flaw detector 11, bar steel 2 rolled by rolling machines 9 passes through the center part of a cross section, and the eddy current flaw detector 11 includes a flaw detection coil 22 which makes the passing bar steel 2 form eddy current by applied current to perform flaw detection, the flaw detection coil 22 is installed in a recombination carriage 12 on the exit sides of the rolling machines 9 and on which the rolling machines 9 are loaded. The flaw detection coil 22 is installed on the exit side of the rolling machine 9 on the downstream side most among the rolling machines 9 loaded on the recombination carriage 12.;COPYRIGHT: (C)2013,JPO&INPIT
