Summary

This paper presents a comparison of three-dimensional steady state calculations of mass and heat transport with temperature and sump profile measurements during the DC casting of rolling ingots of an AA3004 and AA5182 alloy. The calculations are made with different CFD codes, which have been cross-checked in a previous benchmark. The temperatures are measured in specific planes of the melt pool using an array of thermocouples. In addition, the shape of the solidification front is scanned with a mechanical device. Simulated thermal fields and measured temperatures are compared for two completely different flow situations: In the first case the usual casting technique using a spout and distributor bag is applied, while in the second case the distributor bag is removed. Since certain features of the temperature field pattern are closely related to specific flow phenomena the comparison provides a means to assess the validity of the flow calculations. In both cases the results agree well with the related measurements.
