Abstract

L'invention concerne un ensemble résistant à l'abrasion pour une chaîne de protection de pneu, la chaîne de protection de pneu et un procédé de fabrication de la chaîne de protection de pneu. La chaîne de protection de pneu comprend une structure en treillis formée par liaison d'ensembles résistant à l'abrasion (1) constitués d'un matériau en acier à teneur moyenne en carbone et d'anneaux de liaison (2) constitués d'un matériau en acier au manganèse à faible teneur en carbone. Dans ce procédé de fabrication, la liaison par soudage généralement pratiquée pour les anneaux de liaison dans les chaînes de protection de pneu est remplacée par une liaison par soudage d'ensembles résistant à l'abrasion, ce qui améliore l'efficacité d'élimination des bavures générées après le soudage. Dans le même temps, les anneaux de liaison constitués d'un matériau en acier au manganèse à faible teneur en carbone et les ensembles résistant à l'abrasion constitués d'un matériau en acier à teneur moyenne en carbone sont chauffés séparément, ce qui permet d'éviter des situations indésirables telles qu'une trempe incomplète, une fissure de trempe et similaire, et de prolonger considérablement la durée de vie des ensembles résistant à l'abrasion et des anneaux de liaison.
