<p>PURPOSE:To stabilize rolling and to improve the rolling yield by detecting the herring bone of a rolled stock at the outlet side of a rolling mill and controlling the outlet side flowing angle of the rolled stock. CONSTITUTION:A herring bone detector 11 is provided at the outlet side of the rolling mill equipped with work rolls 2, 3 and a deflector roll 1 capable of adjusting the height position and deflector roll position detector 14 are respectively arranged. In the case of rolling a rolling material 1, an aligning screw 18 is adjusted with watching the output of the detector 14 by a roll height adjuster 17 when the herring bone detector 11 detects the herring bone generation of the material 1 and the height position of a deflector roll 10 is controlled to adequately adjust the outlet port flowing angle theta of the material 1. Owing to the herring bone being corrected by the adjustment of the angle theta, the rolling is stabilized and the rolling yield is improved due to the rolling quality being improved.</p> |
