Verfahren zur Herstellung von monokristallinen Stücken
摘要
A process and apparatus for fabricating monocrystalline castings are disclosed in which molten metal is poured into a mold having vertically arranged, individual mold cavities, the solidification front is controlled to progress vertically upwardly from the bottom, and a single crystal grain is selected by a selection device placed in the lower part of the mold. The invention consists in directly superposing a multiplicity of individual mold cavities one above the other in a string, several such strings capable of being placed in parallel between a common metal sprue cup and a chilled plate to increase production capacities.
