    Abstract: Systems and methods for measuring the thermal crown of rolls in-situ (e.g., at high temperature) either inside or outside the rolling mill can include sensors that measure propagation times of mechanical waves through the rolls. In some embodiments, one or more sensors are used to measure the propagation times of ultrasonic waves traveling inside the roll and normal to the roll's axis. These measurements can be taken when the roll is still hot and can be used to determine in real-time the thermal expansion at various points along the roll.

    Abstract translation: 用于在轧机内部或外部原位（例如在高温下）测量辊的热冠的系统和方法可以包括测量通过辊的机械波的传播时间的传感器。 在一些实施例中，使用一个或多个传感器来测量在辊内行进并垂直于辊的轴线的超声波的传播时间。 当辊仍然很热时，可以进行这些测量，并可用于实时确定沿轧辊各个点的热膨胀。

    Abstract: A contactless looper for a metal substrate includes an entrance, an exit, and at least one deflection device between the entrance and the exit. The contactless looper is configured to receive a metal substrate moving in a processing direction from the entrance to the exit and impart a deflection along the processing direction in a metal substrate such that a position of the metal substrate at the at least one deflection device is vertically offset from a height of the metal substrate at the entrance of the looper. A method of processing a metal substrate with the contactless looper includes receiving the metal substrate at the entrance of the contactless looper along a passline, imparting a deflection in the metal substrate with the looper, and passing the metal substrate out the exit of the contactless looper.
