The conventional width rolling method is explained with reference to Fig. 1 (a) to (c). The gap G between the left and right vertical rolls (α) is set to a predetermined dimension, and the planar shape is formed as shown in Fig. 1 (a). A rectangular slab (S) is passed between vertical rolls (α) and rolled in width,
Next, the width rolling of the slab (S) is performed again by narrowing the gap G between the vertical rolls (, 11), and further width rolling is performed by narrowing the gap G between the vertical rolls (α).The number of times this width rolling is performed is rolled a predetermined number of times according to the rolling schedule P-rule.

However, when the slab (S) is width-rolled, a fishtail (h> (b) occurs at the front and rear ends of the slab. This fishtail (15) (i5'J has a negative effect on the product yield. The length of the fishtail (b) on the rear end side in the slab advancing direction increases as the number of width rolling increases and the width reduction amount increases, and the length l!2 of the fishtail (b) on the rear end side in the slab advancing direction is the length of the fishtail (b) on the leading end side in the slab advancing direction. This is about twice as large as 12.By the way, this can be briefly explained as follows.

Next, move the vertical roll (3) forward and move the vertical roll (3) (
3) Narrow the gap between them to a predetermined dimension, move the slab (S) in the opposite direction to that shown in FIG. 6 (c), and perform width rolling as shown in FIG. 6 (g). The amount of indentation of the vertical roll (3) during this width rolling is made larger than the amount of indentation of the mold (9) during preform pressing. @The width W4 of the slab (S) after rolling is w-2, which is the original width W of the slab (S) minus the indentation amount y (see Figure 6 (c)) by the mold (9).
It becomes smaller than y. Also, during this width rolling, the slab 0)
A slight front fishtail (TI) occurs at the leading end in the direction of travel, but not at the rear end.

Thereafter, the gap between the vertical rolls (3) (3) is successively narrowed in the same manner as shown in Figure 6 (force (shi)), and the slab (
S) is sequentially moved in the opposite direction to perform width rolling of the slab β). A front fishtail (T2) is generated at the leading edge of the slab (S) in the advancing direction due to the width rolling of Figure 6 (fl), and a front fishtail (T2) is generated at the leading edge of the slab (Sl) in the advancing direction due to the width rolling of Figure 6 (S). The fishtail becomes a front fishtail (T1') that is larger than the front fishtail (TI), and the rear end fin 7: y-7--/

In this example, the number of times the front fishtail occurs is 3.
Since the number of times R1 of backfish tail is 1 in 3 times, if calculated in the same way as in the conventional example, the provisional evaluation point P is P =
3X1+2X = 5, which is 4 points less than the conventional case. This means that the fishtail is reduced compared to the conventional example.
