Abstract：Prediction and control of steel microstructure during continuous casting process is an essential task for steel production. Studies on the micro- structural parameters, which are hardly measured directly during high temperature solidification process, have significance for that purpose. Dendrite growth is an important phenomenon during steel solidification process, which is the main existing style in the inner side of the solidifying steel. In the current paper, a simplified numerical method for the dendrite growth was used to analyze and calculate some micro- structural parameters for both medium carbon steel and AISI304 type stainless steels under different casting conditions. The dendrite tip radius, dendrite growth velocity, dendrite arm spacing, temperature gradient and the dendrite tip temperature in the front of solid and liquid interface were investigated and comparisons of these parameters for the two steel grades were carried out. Parametric studies for these two steel grades were also studied. The comparisons showed that the micro- structural parameter values of stainless steel were all smaller than that of the carbon steel due to its special compositions and solidification mode characteristics.
