FIG. 1 is a sectional view showing the structure of a bright continuous annealing furnace. That is, in the bright continuous annealing furnace for annealing the elongated metal rolled sheet material 1, the cooling device 3 is arranged on the outlet side of the heating device 2 in the traveling direction of the elongated metal rolled sheet material 1. A circulation blower 4 and a radiator 5 are attached to the cooling device 3, and are connected to the cooling device 3 by a discharge pipe 6 and a suction pipe 7 of the circulation blower 4. Inside the cooling device 3, a plurality of shielding plates 8 are installed vertically extending in a fold shape toward the center,
The cooling atmosphere gas 9 discharged from the discharge pipe 6 is sprayed from the discharge ports 11a, 11b, 11c toward the running direction of the elongated rolled metal sheet 1 inserted through the center thereof, and the rolled rolled metal sheet 1 and the shielding plate 8 is sucked into the suction ports 12a, 12b, 12c on the other side, respectively,
It is configured to return to the radiator 5 and the circulation blower 4 via the suction pipe 7 and circulate.

が可能となる。Therefore, the cooling atmosphere gas 9 supplied from the discharge pipe 6 and discharged from the discharge ports 11a, 11b, 11c is jetted in the traveling direction of the elongated metal rolled sheet 1 through the plurality of shielding plates 8. . Then, through the gap between the shielding plate 8 and the elongated metal rolled plate material 1, the suction ports 12a, 12
Although it is sucked by b and 12c, it is narrowed by the plurality of shielding plates 8 and the elongated metal rolled sheet material 1 and comes into contact with the elongated metal rolled sheet material 1, where the flow velocity increases and flows. For this reason, it becomes possible to improve the cooling efficiency with a relatively small flow rate of the atmospheric gas.

とができる。In the above example, the shield plate 8 is formed in the shape of a plate fold, but it is formed in a mountain shape between the discharge port 11 and the suction port 12 as shown in FIG. The cooling efficiency may be increased by allowing the gas 9 to flow smoothly. Further, as shown in FIG. 3, the shielding plate 8 on the discharge port 11 side is formed in a sawtooth shape with a large inclination, and the discharged cooling atmosphere gas 9 is more smoothly guided to the long metal rolling plate material 1 to improve cooling efficiency. It is also possible. Further, in the above example, the case where three shield plates are provided has been described, but the larger the number, the higher the cooling efficiency.

Further, the space of the bright continuous annealing furnace can be shortened, and the productivity can be improved without lowering the annealing speed of the long rolled metal sheet material.
