Abstract (en)
The process consists in casting an insert in a first mould, in arranging the insert thus cast in a second mould and in casting the part in this second mould around the insert, so as to form a mechanical link between the two castings. The wear-resisting part thus cast advantageously comprises an insert with a high resistance to wear, whilst the rest of the part is made from a more ductile material which is resistant to mechanical stresses. Application to grinding rollers and to hammer mill hog plates. <IMAGE>
Abstract (fr)
Le procédé consiste à couler un insert dans un premier moule, à disposer l'insert ainsi coulé dans un second moule et à couler la pièce dans ce second moule autour de l'insert de manière à former une liaison mécanique entre les deux coulées. La pièce d'usure ainsi coulée comporte avantageusement un insert à haute résistance à l'usure tandis que le reste de la pièce est en un matériau plus ductile résistant aux sollicitations mécaniques. Application aux galets de broyage et aux marteaux de broyeurs. <IMAGE>
