The invention relates to the technical field of precision casting, and discloses a directional solidification device and manufacturing equipment for single crystal castings. The directional solidification device of the single crystal casting includes at least one cooling contact and a contact control module, the cooling contact is used to locally cool the single crystal casting mold shell, and the contact control module is used to control the The cooling contact moves in the cold chamber to contact specific parts of the single crystal casting mold shell for local cooling. The invention strengthens the cooling of the specific part of the single crystal casting mold shell, accelerates the local cooling and solidification of the specific part of the single crystal casting mold shell, forms an ideal solidification sequence of the single crystal casting, avoids miscellaneous crystal defects, and improves the single crystal casting process. Yield rate and quality of crystal castings.
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 ...
