STATISTICAL DIAGNOSTICS OF ROLL SURFACE DEFECTS DOI: 10.22184/2499-9407.2021.22.1.64.68
An article proposes to evaluate the surface quality on the basis of statistical processing of the measuring results of deviation of the surface shape of the rolls, considered as a random spatial process. As an estimate of the diagnostic parameter, the value of the correlation function of the measuring signals corresponding to the adjacent surface areas is used, which creates the prerequisites for increasing the reliability of monitoring and diagnostics of rolling mills.
