A multiple section bars straightening/cutting system in a bar rolling line comprises a multiple section bars straightening apparatus, an inlet side introduction pinch roller, a multiple traveling section bars cutting apparatus and a rear surface tilting table having an outlet side introduction pinch roller. The multiple traveling section bars cutting apparatus includes a fixed blade and a moving blade each having a plurality of calipers formed in accordance with the cross-sectional shapes of the section bars. The rear tilting table tilts in the direction in which the blades of the multiple traveling section bars cutting apparatus move in synchronism with the movement of the blades.

Multiple bar straightening and cutting system in bar steel rolling line

A multiplicity of cooled steel products, after having been severed from an as-rolled steel, divided into sectional bars and delivered to and accumulated on a cooling hearth, are taken from the cooling hearth, and delivered to a multi-bar straightening machine. There, simultaneously with straightening, a predetermined distance from the leading ends of the bars is measured simultaneously, the forward movement of the bars is interrupted after they have advanced by said measured distance, and said forward portions are cut.
