な影響を及ぼし問題となっていた。In this case, there is a distance of 15 to 20 mm (30 to 40 mm on both sides) between the pressure lower surface of the material to be rolled of the vertical rolls and the guide surface of the side guides, and this vertical roll rolling mill is about 2.5 m from the center of the finishing rolling mill. Since the tail end of the material to be rolled cannot be properly guided by the side guides after passing through the vertical roll rolling mill, it is installed between the vertical roll rolling mill and the finish rolling mill. The rolled material oscillates to the left and right and becomes slanted, and only one of its tail ends makes strong contact with the guide surface of the side guide and bends and bites into the finish rolling machine as it is, so-called tightening occurs, Defects such as flaws and the suspension of rolling work for that reason have a great impact on yield, facility maintainability, and operating rate, and have been a problem.

And 32 is a PG attached to one of the shafts of the left and right vertical rolls 11, 11. When the HMD 31 detects the tail end of the material S to be rolled, this detection signal is transmitted to the control device 33. On the other hand, since the PG32 converts the rotation speed of the vertical roll 11 into a pulse and transmits it to the control device 33, the pulse count number from the time when the HMD31 detects the tail end of the material S to be rolled is HMD31.
When a value corresponding to the mutual distance 1 between the vertical roll and the vertical roll 11 is reached, a vertical roll rolling machine passing signal at the tail end of the material to be rolled can be transmitted. With this signal, the vertical roll mill 1
When the electric motor 15 of the drive unit for moving the housings 13 and 13 is started, the side guides 21 and 21 (the guide rollers 22 and 22 when the guide rollers 22 and 22 are provided) are provided on both end surfaces of the material S to be rolled together with the housings 13 and 13. Contact or minute gap (about 5m on each side)
Tighten the side guide opening until it reaches m).
