Structural degradation and damage caused by a system of cracks to the steel of metallurgical equipment

Abstract

We develop an automated method for the quantitative analysis of a system of cracks aimed at the diagnostics of the state of rollers in the machines for continuous casting of blanks. A structural methodology of the identification of cracks is proposed and the efficiency of detection of cracks on the basis of computer processing of digital images is demonstrated. We also compare the parameters of a system of cracks on the oxidized surfaces of rollers when the outer layer is removed.
