Definitions
- Each cast basket strainer 2 can have, e.g., 2 to 5 cavities 13 .
- the plates each have a cast basket strainer 2 of approximately the same width (from one plate wall 10 to the opposite plate wall 10 ) and heights/lengths (from the upper edge of the partition 8 to the lower one), but plates of different thicknesses are preferably produced in a cast basket strainer 2 at the same time.
- the height resulting from the vertical alignment of the cavities 13 results in each case in a metallostatic pressure which has a positive effect during casting. The casting process is also faster as a result.
- the different casting components such as the longitudinal wall 5 , partition 9 , plate wall 10 can each be exchanged/replaced with one another.
- the casting components are fabricated, e.g., from GJS. All casting components can be finished.
