Abstract

Process for the manufacture of a roller composed mainly for the guidance of packages in a continuous casting installation, comprising two concentric zones of different composition, characterized in that an external zone of stainless steel is formed by casting up to approximately 650ºC containing 11, 5 and 14.5% of chromium, an inner zone of non-drawn steel of low carbon content or modular cast iron is formed by casting, which has a coefficient of linear expansion higher than that of the metal of the external zone, and the roller thus causing a differential contraction in the two areas of the roller, which creates in the external zone compression forces that oppose the formation of cracks.
