摘要： A method for manufacturing a metal component using lost-wax casting is provided. The component is made of, for example, nickel alloy, with a columnar or monocrystalline structure with at least one cavity of elongate shape. The method includes creating a wax model of the component with a ceramic core corresponding to the cavity, creating a shell mold around the model, placing the mold in a furnace, with the base standing on the sole of the furnace, pouring molten alloy into the shell mold, solidifying the poured metal by gradual cooling from the sole in a direction of propagation.

摘要： A method for manufacturing a metal component using the lost-wax casting method is provided. The component is made of nickel alloy, with a columnar or monocrystalline structure with at least one cavity of elongate shape. The method includes creating a wax model of the component with a ceramic core corresponding to said cavity, the ceramic core comprising a first land for holding at one longitudinal end and a second land for holding at the opposite end, creating a shell mold around the model, the mold comprising a base and the first land of the core being at the same end as the base, placing the mold in a furnace, with the base standing on the sole of the furnace, pouring the said molten alloy into the shell mold, solidifying the poured metal by gradual cooling from the sole in a direction of propagation. The core in one example is secured to the shell mold by an anchor providing anchorage between the first land of the core and the wall of the mold, the second land of the core being retained in the mold by a retainer that slides on the wall of the mold.

摘要翻译： 提供一种使用失蜡铸造方法制造金属部件的方法。 该组件由镍合金制成，具有至少一个细长形状的空腔的柱状或单晶结构。 该方法包括用对应于所述空腔的陶瓷芯制作组件的蜡模型，陶瓷芯包括用于保持在一个纵向端的第一焊盘和用于在相对端保持的第二焊盘，在模型周围形成壳模 所述模具包括基座，并且所述芯部的所述第一平台与所述基座处于相同的端部，将所述模具放置在炉中，所述基座站立在所述炉底上，将所述熔融合金倒入所述壳模具中， 通过在传播方向上从鞋底逐渐冷却来固化浇注的金属。 一个示例中的芯通过锚固件固定到壳模具，该锚固件在芯的第一焊盘和模具的壁之间提供锚固，芯的第二焊盘通过在壁的壁上滑动的保持器保持在模具中 模具。
