CONTINUOUS MAGNETIC POWDER INSPECTION EQUIPMENT OF LONG SIZE STEEL BILLET

PURPOSE:To magnetize efficiently and uniformly a long size steel billet, and to detect a flaw extending over a wide dimension range, by providing a rack base being freely movable in the right angle direction against the truck running direction, a equipment for detecting the lateral position of the steel billet, etc., on a magnetizing equipment. CONSTITUTION:A inspection equipment is provided with a magnetizing equipment 40 provided with an electromagnet 56, a magnetic powder blower 65 placed so as to be adjacent to the electromagnet 56, and a truck 71 which places a steel billet M on it and runs in its longitudinal direction. Also, the magnetizing equipment 40 is provided with a rack base 41 placed so as to stride over the truck 71 and being freely movable in the right angle direction (lateral direction) C against the truck running direction (longitudinal direction) B, equipments 47, 106 and 111 placed so as to be opposed to the steel billet M on the truck 71, and for detecting a position of the lateral direction C of the steel bloom M, and a member 49 for suspending the electromagnet 56 from the rack base 41. According to such a constitution, a long size steel billet is magnetized effiiently and uniformly, and a flaw can be detecting extending over a wide dimension range.
