<p>PURPOSE:To reduce the generation of heat streak and to minimize the reduction of rolling efficiency by detecting whether heat streak on the surface of a steel plate exists or not and adjusting the rolling speed. CONSTITUTION:Heat streak detectors 22a, 22b are mounted on the outlet side 23a, 23b of a rolling mill, whether the heat streak exists or not on the surface of the steel plate is detected, when the heat streak is detected on the surface of the steel plate 12, the rolling speed is lowered and when the heat streak is not detected, the rolling speed is held or increased.</p> |
