The invention relates to a bimetallic casting serving as a wear piece in vertical mills and its method of manufacture. It includes a core (13) made of a ductile cast iron and provided with mechanical bonding elements in the form of pins (15) which are rendered integral with an outer casing (17) by casting, the outer casing being made of a non-ductile wear material having a high chromium content. Such castings are used for being mounted on the hub of a roller of a so-called vertical-axis crushing mill.
La présente invention a trait à un moulage bimétallique utilisé comme pièce d'usure dans les broyeurs verticaux et à sa méthode de fabrication. Il comprend un noyau (13) constitué de fonte ductile et muni d'éléments de liaison mécanique sous la forme de tiges (15) qui sont incorporées à une enveloppe extérieure (17) par moulage, l'enveloppe extérieure est constituée d'un matériau d'usure non ductile dont le contenu en chrome est élevé. De tels moulages sont utilisés pour être installés sur le moyeu d'un cylindre d'un broyeur à axe vertical.
