Ultrasonic Testing of Strip Thickness During Metal Rolling

在板材轧制时测量其金属厚度。防止金属被损坏或留下痕迹。向控制系统提供反馈，以影响轧制过程中的金属轧辊。研究涉及使用超声波来调查板材在轧制过程中的带材厚度。还将调查其他参数，看看在试验轧钢机和全尺寸工业轧钢机上可以观察到什么。这项研究将对金属轧制行业产生影响，因为能够在轧制过程中控制轧制过程，可以节省时间并增加其他价值。为此，这项研究是由塔塔钢铁公司赞助的。使用的超声方法是螺距捕捉斜向超声，脉冲通过毕氏显微镜发送。以前的测量方法使用辐射或依赖物理接触，然而这些方法具有超声波方法被认为可以减轻的限制。该项目与EPSRC的制造目标一致。

Measure the metal thickness of sheet metal whilst it is being rolled. Prevent the metal from being damaged or marked. Provide feedback to a control system to influence the metal rollers during the rolling process.The research involves using ultrasound to investigate the strip thickness of sheet metal whilst it is being rolled. Other parameters will also be investigated to see what can be observed on a pilot rolling mill as well as a full sized industrial rolling mill. The impact this research will have is to the metal rolling industry as being able to control the rolling process during rolling allows for time to be saved and other value to be added. To this end the research is sponsored by Tata steel.The ultrasound method being used is pitch-catch oblique ultrasound and the pulses are sent via a Picoscope. Previous measuring methods have used radiation or have relied on physical contact, however these methods have limitations that the ultrasound method is believe to mitigate.This project aligns to the manufacturing goal of the EPSRC.
