[0049] In order to verify the pre-control effect of the shape of the slab head and tail, the slab cutting and rolling tests were carried out in hot rolling. Taking the test as an example, the pre-control method of the shape of the slab head and tail, the head and tail cut amount of the intermediate slab after rolling and the effect on reducing the cut amount are introduced.
[0050] Slab condition: In order to verify the control effect of the slab head and tail shape pre-control under different bow heights, four groups of experiments were designed. Two slabs with the same thickness and width specifications were selected for each group of tests, one of which was pre-controlled for the shape of the head and tail (the arc bow height of the head is concave, and the arc bow height of the tail is convex), and the other is Conventional cuboid slabs are used for comparison. A total of eight slabs were selected. See Table 1-1 to Table 1-4 for slab-related data.
