Heat Transfer Measurements During DC Casting of Aluminium. Part II: Results and Verification for Extrusion Ingots

  • Chapter
Essential Readings in Light Metals

Abstract

Measurements were carried out during ordinary production runs of DC hot top mould casting of extrusion ingots. Measured values cover the initial shell formation within the mould as well as direct water cooling zones/mechanisms below the mould. A separate two-dimensional mathematical casting model (Dystal) was then used to verify the measured heat transfer values. This was obtained by using these values as input, recalculating observed temperature time curves for selected points moving with the ingot. Also calculated and observed sump profiles were compared.
