Embodiment 1
[0220] manufacture Figure 1 ~ Figure 3 Cooling roll with dimple correction device on the peripheral surface shown, preparation of a cooling roll with this figure 1 The quenched ribbon manufacturing apparatus of the configuration shown.
[0221] The cooling roll was manufactured in the following manner.
[0222] First, prepare copper (thermal conductivity at 20°C: 395W·m -1 ·K -1 , thermal expansion rate at 20°C: 16.5×10 -6 K -1 ) made of a roller base material (diameter 200 mm, width 30 mm), the peripheral surface thereof was subjected to cutting processing to form approximately a mirror surface (surface roughness Ra: 0.07 μm).
[0223] Subsequently, cutting is further performed to form a plurality of substantially parallel grooves with respect to the rotation direction of the roller base material.
[0224] After the grooves are formed in this way, a remaining portion is formed between the grooves arranged in parallel as a convex line.

[0231] In addition to making the shape of the grooves and ribs take as Figure 13 , Figure 14 Except for the shape shown, other cooling rolls were produced in the same manner as in Example 1. At this time, the average width of the grooves, the average width of the ridges, the average depth of the grooves (the average height of the ridges), and the average pitch of the grooves (ridges) arranged in parallel were varied, and six types were manufactured. Cool the rolls. Both use a turntable with three cutting tools at equal intervals, and form three parallel grooves at approximately constant pitches on each part of the peripheral surface. The angle θ formed between the longitudinal direction of the groove and the direction of rotation of the cooling roll was 5° in either case. The cooling rolls of the quenching ribbon apparatus used in Example 1 were replaced with these cooling rolls one by one, and the quenching ribbons were produced in the same manner as in Example 1.

[0233] In addition to taking the shape of the grooves and ribs as Figure 15 , Figure 16 Except for the shown shape, other cooling rolls were manufactured in the same manner as in Embodiment 2, and the cooling rolls of the quenched strip manufacturing device were replaced with the chilled rolls, and the quenched strips were produced in the same manner as in Example 1. The angle θ formed by the longitudinal direction of the groove and the rotation direction of the cooling roller 1 , θ 2 , either of which is 15°.
