Abstract
The apparatus for the production of directionally solidified castings (10) in a vacuum casting plant comprises a cooling attachment with members (60) between a flat cooling plate (6) and the mold shell (2), by means of which member zones of different orientation of the direction of solidification can be produced in the casting. This apparatus is particularly suitable for the production of components in the form of a wheel--e.g. turbine wheels in aircraft jet engines--in which a radial alignment of the texture structure is advantageous in order to increase strength.
