The invention relates to a method for the production of defect-free calibrated steel bars and to the assembly used for same. The inventive method combines a drawing/calibration operation with a crack-control phase and a subsequent mechanical stripping operation comprising chip removal, prior to the cutting of the bars. In this way, the value of the calibrated crack-detection depth corresponds to the surface defects on the bar and is slightly less than the stripping depth of the subsequent successive bar-stripping phase, such that defective bars are removed automatically.
Un procédé de fabrication de barres en acier calibrées sans défauts et une installation pour leur fabrication. Le procédé consiste à combiner le calibrage par étirement avec une phase de commande d'entailles et une opération ultérieure d'écorçage mécanique de la barre par élimination des copeaux avant la découpe des barres de telle sorte que la profondeur du taraudage de la détection d'entailles ait une valeur correspondant aux défauts superficiels de la barre et un plan inférieur à la profondeur d'écorçage de la phase successive de pelage de la barre, ce qui permet d'éliminer de manière automatique les barres défectueuses.
