“…Therefore, the determination of interfacial heat transfer coefficient (IHTC) is vital ahead of the simulation of the solidification process. In fact, the IHTC depends upon multiple factors such as die coating thickness, insulating pads, chill and casting geometries, pouring temperature, surface roughness, alloy composition, metallostatic head, mould temperature and other mechanical boundary conditions [3][4][5][6]. Its determination is often carried out by manual adjustments to reduce the difference between the experimental observation and the numerical prediction.…”

Cooling heat flux effect in both primary and secondary cooling zone has been studied in semi-continuous casting of copper billet. Sufficient cooling is essential to reduce casting defects and to get high productivity, however low rate of solidification is aimed in order to get coarser grain size and softer metal for less losses in extrusion. A three-dimensional numerical model has been developed including solidification behavior of copper through mushy zone. At steady state and constant casting speed, solid shell thickness is monitored during the reduction of cooling rate at mould region to avoid breaking out. Heat flux intensity at mould plays important role not only in the formation of solid shell thickness. But, pool length and mushy zone thickness can be significantly increased by decreasing primary cooling intensity. Increase intensity of secondary cooling zone for two particular cases of primary cooling is tested. First case is tested at mould inlet water temperature of 38˚C, and second case at water temperature of 63˚C. Results showed that the combination of increasing secondary cooling intensity and reduction of primary cooling intensity can increase pool length and mushy zone thickness. Also, it is shown that, secondary cooling intensity can be magnified by up to 1.5 times for cooling water temperature of 63˚C to get pool length close to that of water temperature of 38˚C.
