The invention relates to the technical field of precision coasting and discloses a directional condensing device for a single crystal casting and manufacturing equipment. The directional condensing device for the single crystal casting comprises at least one cooling touch and a touch control module. The cooling touch is used for locally cooling a single crystal casting mold shell, and the touch control module is used for controlling the cooling touch to move in a cold chamber to be in contact with a special part of the single crystal casting mold shell to be cooled locally. By reinforced cooling of the special part of the single crystal casting mold shell in a targeted manner, the local cooling and condensing of the special part of the single crystal casting mold shell are accelerated, sothat the ideal condensing sequence of the single crystal casing is formed, the defects of mixed crystals are avoided, and the yield and quality of the single crystal casting are improved.
Description
technical field [0001] The invention relates to the technical field of precision casting, in particular to a directional solidification device and manufacturing equipment for single crystal castings. Background technique [0002] Existing single crystal castings, such as single crystal blades, are usually made of single crystal structure by precision casting and directional solidification. In the vacuum furnace, the superalloy is melted and poured into the high-temperature ceramic mold shell and slowly descends into the cold zone at a set speed, resulting in the bottom-up cooling of the ceramic mold shell and the directional solidification of the casting in the ceramic mold shell, finally forming a high temperature Alloy single crystal structure. However, the heat dissipation conditions and solidification process of various parts of single crystal castings are not well controlled, and the crystal growth is difficult to be guided correctly, and miscellaneous crystal defects ...
