| Abstract Scope |
The cooling configuration of the mould has a significant influence on the heat transfer behaviour of the ingot. In this paper, taking a large 500 × 2000 mm aluminium alloy flat ingot as the subject of study, a numerical model coupling melt flow and heat transfer during direct-cooling casting was established to investigate the effects of the mould’s copper plate thickness and effective length on the heat transfer behaviour of the ingot. The results indicate that increasing the thickness of the copper plate raises the temperature of the ingot’s hot face and leads to a deeper liquid pocket; extending the effective length of the mould increases the thickness of the solidified shell as the ingot exits the mould, causing the liquid pocket to deepen further. This study provides theoretical guidance for optimising the mould cooling structure and improving the heat transfer behaviour of large aluminium alloy flat ingots. |
