Measurement of the flatness of cold rolled steel strip or aluminum foil is a vital aspect of production quality control. Cold lamination control based on the results of this measurement crucially affects production efficiency, but further processes can modify this flatness, and it can be even lost when strip becomes cold. We describe a low-cost flatness(More)
This article describes a series of methods to detect thickness defects in DWI tinplate. These methods provide information to identify the origin of the defects, allowing fast corrections and, therefore, improving mill performance. In this approach, an adapted thickness signal is spatially sampled from the input stages of the mill's last X-ray gauge. The(More)
The draw wall ironed (DWI) tinplate market clearly trends to demand a reduction in thickness, which implies stricter tolerance levels as small variations could result in problems in the manufacturing process and therefore customer's dissatisfaction in a highly competitive market.
