Abstract (en)
[origin: WO2011121251A1] The invention relates to a method for manufacturing a bi-material ferrule, consisting of an outer annular ferrule (17) and an inner annular ferrule bonded together; the bottom pouring of the outer ferrule (17) is carried out in a casting space (7) defined by a wall of a first ingot mould and by an upwardly movable outer wall (8) of a second ingot mould that is concentric to the former; said movable wall (8) of the second ingot mould is raised such as to uncover the skin of the outer ferrule (17) which is solidified thereagainst; bottom pouring and solidification of the inner ferrule are carried out in a casting space defined by said skin and a stationary inner wall (9) of said second ingot mould, the bonding of the two ferrules being carried out by diffusion between said ferrules; and forging and/or one of said bonded ferrules is optionally carried out. The invention also relates to a device for using said method and to a ferrule thus produced.
