Abstract
PURPOSE:To shorten the flaw detection time required for one steel plate by installing a draining roll at a distance which is an integral multiple of the overall effective flaw detection width of a center flaw detecting mechanism device and eliminates the need to stop or decelerate the steel plate. CONSTITUTION:The draining device 6 is arranged on the downstream side of the center flaw detecting mechanism device 2 at the distance which is an integral multiple of the overall effective flaw detection width of the device 2 in a conveying direction. The device 2 performs flaw detection while scanning in the width direction of the steel plate 1, and conveys the steel plate 1 by the overall effective flaw detection width of the device 2 and stops it when one flaw detection scan is completed, and this operation is repeated. In this process, the front end of the steel plate 1 stops right below the device 6 and need not be stopped or decelerated unnecessary for the plate contacting of the device 6. Consequently, the flaw detection time required for one steel plate is shortened.
