Flatness measurement under hot conditions often leads to inaccurate and unreliable results. Speed, rapid and large temperature variations, heat shimmering, cumbersome calibration, water and moist are factors that complicates the measurement. This applies to all applications in hot strip and plate mills, eg. after roughing mill, finishing mill, after laminar cooling and hot leveling.
To overcome this, Shapeline has developed a solution, VeriShape, for measurement on hot material based on laser lines instead of laser points or white light.
VeriShape can be used in quarto mills, such as roughers or plate mills, but also in high speed finishing strip mills.
