In the production of hot rolled steel coil,it is necessary to detect the center position of steel coil,so as to facilitate the normal process of bundling and code spraying of steel coil.Because of the harsh production environ-ment of hot rolled steel coil,contact measurement technology is usually used to detect the center position of steel coil.The detection error caused by the impact deformation of the contact assembly in the detection device for the center position of steel coil is analyzed.In order to reduce the impact,the original contact assembly is improved into a buffer contact assembly.The detection error caused by the outer surface shape of steel coil is analyzed,and the analytical formula of error compensation is fitted by BP neural network.The detection error caused by the difference of the ending position of strip steel is analyzed,and the position of contact is judged by combining two groups of detection devices.Through the above research,the corresponding compensation scheme is put forward,which can effec-tively improve the detection accuracy of contact steel coil center position detection technology.
