Definitions
- the Applicant is the designer of the COBAP process ESS (registered trademark) defined in the European patent 1 19 365.
- FIG. 4 is a diagram representing, according to the ratio of compressibility and deformation, the curves corresponding to cores obtained according to the known techniques, blown salt core, blown sand core, sintered salt core, and according to the invention, compacting core isostatic.
- the foundry preform thus obtained is then forged with the salt core compacted by isostatic pressing at a pressure of 600 to 700 MPa.
- the salt core which has been compacted undergoes no loss of volume during the forging operation being protected by the preform itself and having been compacted with a virtual absence of vacuum between the constitutive grains of the core.
- the configuration of the core according to the invention gives it a very low compressibility.
- the design of the casting which is then forged with the core according to the invention is facilitated.
- the press force during the forging serves only to deform the core and the metal in a deviatoric manner, the rise in pressure not being affected by a decrease in the volume of the core.
- the deformation rate of the salt nucleus by isostatic compression is only 4%, whereas the deformations for a sintered salt core are 24.2%, for a sand core of 29% already at a pressure of 350 MPa, and of , 2% for a puffed salt core.
- the Applicant has therefore demonstrated the use of a salt core as part of the casting process of aluminum or aluminum alloy casting for the production of a foundry preform, said preform being transported for a forging operation at a pressure of 600 to 700 MPa, the use of a salt nucleus obtained by isostatic compression which exhibits, during the forging, a very small compression deformation of the order of 3 to 6%, and more specifically 4%, which makes it possible to work the parts with greater reliability.
