Claims

[Claims for Utility Model Registration] (1) In a long steel cold shear line, the frame of the sizing stopper downstream of the cold shear is movable in the direction of the cold shear line;
A sizing stopper configured to move the relative position of the sizing stopper with respect to the cold shear to a corrected position corresponding to the amount of heat shrinkage of the bar steel, based on a signal from a position detector of the frame and a signal from a temperature sensor upstream of the cold shear. A sizing cutting device characterized by having: (2) The sizing cutting device according to claim 1, wherein the sizing stopper is incorporated in a rear roller table movable in the direction of the cold shear line downstream from the cold shear. (3) The sizing cutting device according to claim 1, wherein the frame of the sizing stopper is independent from the frame of the rear roller table.
