Resumo

The roll wear in a hot section mill for copper is measured under industrial conditions. Fatigue and oxidative wear are found to be the main types of wear, which consist the appearance and development of a network of erosion cracks. The technique of quantitative wear measurement consists in roll remachining at a given step across the worn layer depth and fixation of the presence or absence of a network of erosion cracks on them. The finite element method is used to perform a mathematical simulation of the rolling process and to determine the main parameters, namely, the velocity, the pressure, the slip, and the full slip path on the contact surface. The obtained distributions of the parameters are compared with the results of industrial measurements. Wear localization zones are shown to correspond to the areas of intense slip and high normal pressure in roll passes. The developed recommendations point to practical importance of this work.
