Embodiment Construction
[0025] Figure 2 shows the equipment layout of the shearing line. It can be seen from the figure that the planar shape detection device PSG 11, online ultrasonic flaw detection equipment UST 12, cropping shears 13, double shears and Split cut 14, cut to length cut 15. Among them, the UST 12 is moved from the usual installation position, that is, the cut-to-length shear 15, to the front of the cutting head shear 13 and behind the PSG 11, which is a necessary means to realize this cutting optimization. Rolling slab 2 completes the shearing to finished plate 3 according to the flow process shown in Figure 1 on such a shearing line.
[0026] 1. First, roll the slab to the entrance roller table of the plane shape detection device PSG 11, and use the plane shape detection device PSG 11 to detect the plane shape of the large slab to be rolled to obtain the plane data of the rolled slab. The plane data is an edge coordinate value obtained by the plane shape detection device PSG 11 at ...
