摘要: The roll gap is feedback controlled in that the actual gap is detected, compared with a reference for formation of an error signal which in turn controls the relative position of the rolls. That feedback system is supplemented by augmenting the error by a signal that is directly proportional to the time derivative of the rolling force and of the stock width and inversely proportional to the force itself.
摘要翻译: 与用于形成误差信号的参考值相比较,检测到辊隙是因为检测到实际的间隙,而误差信号又用于控制辊的相对位置。 该反馈系统补充了通过与轧制力的时间导数和坯料宽度成正比的信号来增加误差,并且与力本身成反比。

摘要: Two bearing sections pertaining to feelers on arms are maintained in engagement with journal axles of two rolls and a pair of transducer elements on the arms monitors therein distance from each other in representation of the roll gap. The arms can be pivoted out of the way in that the bearing sections are removed from between the axles.
