Abstract

L'invention concerne l'industrie des métaux réfractaires frittés. On obtient un assemblage cylindrique réfractaire par manchonnage d'un corps cylindrique, en utilisant l'effet de contraction dû au frittage d'un moulage cylindrique réfractaire creux, ajusté autour du corps cylindrique. Application pour restauration de cylindres, piliers, arbres, etc, usés, en matériaux réfractaires de compositions semblables ou différentes de celle du manchon.
