Abstract: The present invention is directed to solving the problems associated with the detection of surface defects on metal bars as well as the problems associated with applying metal flat inspection systems to metal bars for non-destructive surface defects detection. A specially designed imaging system, which is comprised of a computing unit, line lights and high data rate line scan cameras, is developed for the aforementioned purpose. The target application is the metal bars (1) that have a circumference/cross-section-area ratio equal to or smaller than 4.25 when the cross section area is unity for the given shape, (2) whose cross-sections are round, oval, or in the shape of a polygon, and (3) are manufactured by mechanically cross-section reduction processes. The said metal can be steel, stainless steel, aluminum, copper, bronze, titanium, nickel, and so forth, and/or their alloys. The said metal bars can be at the temperature when they are being manufactured. A removable cassette includes various mirrors. A protection tube isolates the moving metal bar from the line light assembly and image acquisition camera. assembly and image acquisition camera. A contaminant reduction mechanism applies a vacuum to remove airborne contaminants.

Abstract: La p resente i nvencion s e d irige a r esolver l os p roblemas a sociados c on l a deteccion de defectos de la superficie sobre barras metalicas asi como a los problemas asociados con la aplicacion de sistemas de inspeccion de placas metalicas para las barras metalicas para la deteccion de defectos no destructivos en la superficie. Se desarrolla un sistema de formacion de imagenes especialmente designado, que esta comprendido de una unidad de computo, lineas de luces y camaras de analisis de lineas de altos indices de datos, para el proposito antes mencionado. Los objetivos de la aplicacion son (1) las barras metalicas que tienen una circunferencia/proporcion de area transversal igual a una mas pequena que 4.5 cuando e l a rea transversal es una unidad para la forma dada, (2) cuyas secciones transversales son redondas, ovales o en la forma de un poligono y (3) se fabrican mediante procesos de reduccion mecanicamente transversal. Dicho metal puede ser acero, acero inoxidable, aluminio, cobre, bronce, titanio, niquel y asi sucesivamente y sus aleaciones. Dichas barras metalicas pueden estar en la temperatura cuando estan siendo fabricadas.
