ABSTRACT:
A method for viewing a glowing steel body such as a billet for flaw inspection or identification. The process identification includes the step of providing identifying indicia on a surface of the billet. The billet is viewed by illuminating the billet with a source of bright light to create shadows so that the indicia or flaws can be seen, and viewing the billet from behind a protective device which permits intermittent viewing of the object. Apparatus for carrying out the method includes a shutter by which the light emitted by the billet is attenuated. The shutter employs a pair of rotatable disks having spaced, parallel axes of rotation and the disks are overlapped near their peripheries. Each disk includes a viewing opening disposed near its periphery. When the disks are rotated in the same direction and at different angular speeds, the viewing openings periodically are aligned for short periods of time. The apparatus also includes a pulsed light source having a xenon flash lamp connected across capacitors. The shutter includes a timing mechanism so that the lamp is flashed when the shutter permits viewing of the object.
