Beschreibung
Zusammenfassung:	The invention discloses an anti-rupture bottom plate for a single-crystal casting and a preparation method of the anti-rupture bottom plate. With the adoption of a special bottom plate case design, bottom plate rupture and deformation caused by pulling due to temperature differences in different case areas can be eliminated, and the single-crystal casting success rate is improved. 本发明公开了种单晶铸件用防破裂底板及其制备方法，采用特殊底板模壳设计，消除模壳不同区域温度差异造成拉扯而形成的底板破裂和变形，提高单晶铸造成功率。
