The present invention relates to an air supply amount adjusting device of a coil cooling station, and more particularly, to an air supply amount adjusting device which is improved to always maintain the TPM working temperature at 40 to 45 ° C. by adjusting a coil cooling time according to a TPM line working process. It is about.

In general, as shown in Figures 1 to 2, the coil cooling is a cooling fan of the cooling station to cool the coil heated for a long time in the annealing process by blowing to the appropriate temperature 40 ~ 45 ℃ during TPM operation The blowing air generated at 100 is raised to each air outlet through the underground cooling air duct 21 to cool the coil seated on the base plate 18. At this time, when the coil was seated on the base plate 18, the damper that closed the tuyere was opened and closed by hand with a wire rope, which caused a deterioration in workability due to a large number of personnel and time, and also a narrow space between the coil and the coil. There was a problem that a safety accident occurred in one workspace.

Conventionally, as shown in FIG. 1, in order to solve the above problem, a steel tube 14 is installed between the cooling air duct 21 and the base plate 18, and a damper 7 inside the steel tube 14. In the air inlet is built in, a flange (2) is installed on one side of the outer peripheral surface of the steel tube (14) and inserted into the disc housing (1) to be moved up and down by the coil; A connect arm 4 having an upper end rotatably coupled to a fixed rod formed horizontally on one side of the flange 2; A connect weight 3 having one side rotatably coupled to the lower end of the connect arm 4 and the other side being biased; The rotary tube penetrates to one side of the steel tube 14 so that one end of the steel tube 14 is fixed to the stop of the connect weight 3 and the other end of the rotating tube is coupled to the damper 7.

Therefore, the damper 7 blocks the tuyeres at the weight of the connecting weight 3 at the same time, and the up and down flange 2 is raised to protrude on the base plate 18 and the coil is positioned on the base plate 18. When it is in contact with the damper 7, the damper 7 is opened and closed by the action of the connect arm 4 by pressing the protruding up and down flange 2.

However, in the conventional apparatus as described above, the cooling time of the coil is always constant since the damper 7 of the tuyere can only open and close. Therefore, it is not only difficult to unitize the work process, but also becomes a factor that causes workability deterioration and quality defects during the TPM work, which is beyond the proper temperature range of coil cooling.

In order to solve the above problems, the present invention controls the coil cooling time according to the blowing amount by adjusting the damper of the blower so as to cool the coil by controlling the coil to an appropriate cooling temperature range in cooling the coil in the coil cooling station.
