ABSTRACT:
Bimetal casting of wearing parts including a cast retaining part enclosing a plurality of inserts. The method consists in casting an insert in a first mould, disposing the insert thus cast in a second mould and in casting the part in this second mould around the insert in such a way as to form a mechanical bonding between the two castings. The wearing part thus cast advantageously comprises an insert having a high resistance to wear while the rest of the part is made of a more ductile material which is resistent to mechanical stresses. The primary application is in the realization of crushing wheels, termed ferrules, and crusher hammers.
