In continuous casting, it is difficult to determine the temperature distribution and solidification thickness using experimental techniques. This paper aim at analysing the temperature distribution and solidification thickness of the liquid cast in the mould numerically with respect to the pouring temperature of 1546 oC and mould preheat temperature of 320oC. The Garlerkin Finite element method was used to discretize and analyse the temperature distribution. The pouring temperature dropped from 1546oC to 1532oC for 50sec, after a time interval of 100sec droped to 1525 oC and further dropped to 1513oC at the outlet of the mould zone. This result corresponds with the results obtained from literature which had a mould outlet temperature of about 1515oC. The thickness was observed to increase after some time to about 2.4375cm which aid the downward movement of the liquid cast into the solidifying steel shell.
