第５図に示すものが知られている。[Prior Art] Conventionally, suction type cooling rolls for cooling hot copper strips in continuous annealing equipment or heat treatment lines have been used, for example, as shown in Figs.
The one shown in FIG. 5 is known.

A large number of suction holes 4 having a diameter of φ are provided and communicate with a suction groove 5 cut into a slit shape in the axial direction of the roll cylinder 3. Here, the suction hole 4...
・ is attracted to the suction groove 5 side, which improves the contact between the heated strip 6 and the roll cylinder 3, and also prevents poor contact at the end of the strip 6 due to the crown (axial bulge) of the roll cylinder 3. The strips 6 are brought into contact with each other by the suction force of the holes 4, and the temperature in the middle direction of the strip 6 is made to be uniform. Roll end plates 7, 7 are provided in a direction perpendicular to the axial direction of the roll body 1, and a fixed suction mounting seat 8 is arranged on one side of one end of the roll end plate 7 by a contact angle θ of the slit tube. Gas suction is performed while making contact (as shown in Figure 4). At both ends of the roll body 1 along the axial direction, bearings 9 a + for supporting the roll body 1 are provided.
Rotary joint 1 that performs 9 b s and suction/drainage
0a and 10b are provided.

ストリップ巾方向に不均一な冷却となる。The refrigerant 2 enters from one rotary joint 10a in the direction of arrow It is discharged like this. According to the cooling roll having such a structure, the suction flow path 11 as shown in FIG.
Since it is located at the center of the thickness of the roll body 3, the thickness (1) of the roll body 3 is structurally large and the amount of heat transfer is small. Further, thermal deformation due to the temperature difference (ΔT) of the roll cylinder 3 is large. Note that the amount of heat transfer (ΔT) holds true in FIG. Furthermore, because the temperature difference between the strip contacting part and the non-contacting part in the roll axis direction causes local warping in the roll cylinder 3, both ends of the strip 6 do not contact the roll cylinder 6,
Non-uniform cooling occurs across the width of the strip.
