Abstract (en)
[origin: WO2014111648A1] The present invention relates to a method for manufacturing a metal component using the lost‑wax casting method, the component being made of nickel alloy, with a columnar or monocrystalline structure with at least one cavity of elongate shape, comprising the following steps of creating a wax model (20) of the component with a ceramic core (10) corresponding to said cavity, the ceramic core comprising a first land (14) for holding at one longitudinal end and a second land (16) for holding at the opposite end, creating a shell mould around the model, the mould comprising a base and the first land of the core being at the same end as the base, placing the mould in a furnace, with the base standing on the sole of the furnace, pouring the said molten alloy into the shell mould, directed solidification of the poured metal by gradual cooling from the sole in a direction of propagation. It is characterized in that the core (10) is secured to the shell mould by an anchoring means (40) providing anchorage between the first land (14) of the core and the wall of the mould, the second land (16) of the core being retained in the mould by a retaining means (17) that slides on the wall of the mould.
