66 Robotized magnetic diagnostics complex for the rolls By Sergey Murikov, Igor Artemiev, Vladimir Urtsev, Aleksandr Kudryashov, Egor Murikov, Anastasiya Vitkovskaya, Aleksandr Nichiporuk and Aleksei Stashkov The robotized complex for the magnetic diagnostics of the sheet mill rolls was developed and prepared for full scale production. The complex is installed on the unwork side of a roll grinding machine and can work with machines of any model. The measurement of coercive force allows for evaluating the non uniformity of the roll surface. The use of coercive force measurement adds more information to the other diagnostics methods and substantially improves the reliability of assessment of the roll surface condition.
