The precipitation and growth behavior of titanium nitride (TiN) inclusions during the continuous casting of high carbon wire rod grade steel SWRH 72A was investigated based on the thermodynamic calculations. Titanium is a tramp element in this grade and its pick up in liquid steel mainly takes place from the ladle alloy additions. Titanium in liquid steel is the limiting factor for the growth of TiN inclusions as it diffuses slowly in steel than nitrogen and enriches in interdendritic liquid regions creating favorable conditions for TiN precipitation. It was also observed from this study that the temperature for the formation of TiN inclusion decreased with decrease in titanium for a fixed nitrogen. Titanium nitride inclusions precipitate in steel during solidification even with low titanium and nitrogen content due to the effect of elemental segregation. Solidificationsegregation of both titanium and nitrogen increased with increase in cooling rate and their segregation tendency increased rapidly with increasing solidification fraction. The effect of titanium, nitrogen and cooling rate on the growth radius of titanium nitride inclusion was studied and validated with actual inclusion measurement.
