Abstract Scope |
The stability of the Aluminium DC casting process is dependent on tight control of a multitude of parameters. Even slight fluctuations within the defined production process window of crack sensitive wrought aluminum alloys are potentially detrimental. However, for certain parameters the extent to which their variance can be reduced is severely limited. For that reason, the continuous casting process for AA-7075 rolling slabs is modelled using MAGMA CC. Model assumptions are validated experimentally in an industrial DC casting pit. Different mold and cooling conditions as well as casting temperatures are simulated and their effect on the stress distribution in the slab is investigated. Criteria are developed to assess the tendency towards casting defects, such as center cracks due to process parameter fluctuation. The findings are used to identify potential for process optimization. |
