Abstract

The fluid flow pattern inside the continuous casting mould is mostly asymmetrical about the central plane and oscillating. Present work studies the frequency of flow oscillation for different mould dimensions, SEN position and its configuration, fluid inlet condition into the mould etc. A time average symmetry has been observed in the prevailing flow pattern inside the mould. However, this symmetry is disturbed when the SEN is displaced from its symmetrical position by more than four percent of the mould width. An upward SEN port angle and increase of flow rate increase the frequency of flow oscillation significantly. The use of a buffer over the continuous casting mould does not reduce the frequency of flow oscillation.
