%X To continuously control and improve the surface properties especially roughness(Ra),a surface roughness sensor(SRM) has been developed by CRM and industrialized by AMEPA to measure roughness parameters along with the whole length of the strip on various industrial lines.The selected measurement method is based on the principle of triangulation: a very thin line is projected on the surface and the relief is determined by analyzing the deformation of the line.The method has been validated by comparison with mechanical stylus reference measurement.The correlation between SRM and stylus is in a range of +/-10%.SRM has been installed on various lines and various products: continuous annealing line,tandem(oiled surface),galvanising line(high reflective surface),roll shop(high reflective and roughness surface).As well coated,un-coated,random(e.g.EDT) and deterministic(e.g.EBT) surfaces are concerned.The final result is an on-line sensor for assessing topography.This sensor is presently used in Europe in daily production by some production lines.Four sensors are installed in a compang in China on continuous galvanising line and on continuous annealing line.This leads to a better understanding of the influence of various production parameters on the strip surface with the possibility to directly control the process.
