Abstract

PURPOSE:To pass the tail end of a band steel automatically from a reel to a rolling mill by calculating remaining coil diameter of rewinding side reel and changing driving of above-mentioned reel from current control to voltage control basing on signal of the result of calculation. CONSTITUTION:A current controlling device and a voltage controlling device are provided in driving controlling devices of left and right reels. The remaining diameter of rewinding side reel is calculated by an arithmetic unit and when the coil diameter corresponding to the length of band steel necessary for deceleration is attained, the driving of the reels is changed from current control to voltage control by a remaining diameter signal. Thus, the reel sends out the coil at equal speed with the rolling mill. When the tail end of the band steel passes a tail end detector provided between the rolling mill and rewinding reel, the rewinding side reel also changes current control to voltage control. In this way, the tail end of the band steel can be passed from the reeel to the rolling mill smoothly without stopping operation at each pass.

When the deceleration is completed as described above, 2 to 3 turns of the coil remain on the unwinding reel. By doing this, the unwinding reel will send out the coil at the same speed as the rolling machine, which is the same as feeding by drive.Also, since the grip is open, , there is no problem when the last tail ends off the reel.

Other actual mud example 01 In the reverse type cold rolling mill, it may not be possible to pull out the ash for each bus, and some buses may be automatically operated in forward and reverse directions, and the tail may be removed only in the final pass.In this case, as described above There are cases where the tail end cannot be pulled out smoothly from the rolling mill using only the control method.This is because the tail end is automatically repeated in forward and reverse directions without removing the tail end at each valley pass. This is because the rolled part is not rolled at all, and the thickness of the rolled part is quite different (1 difference), so the roll gap at that time cannot be used for rolling.In this case, the tail end is detected by the tail end detector described above. (double dynamically set the roll gap to the value of the first pass).
