Abstract A mathematical model was proposed to study the influences of temperature fluctuation on initial peritectic solidification process in continuous casting. The variation of interface positions and volume fractions of three different phases—delta, gamma and liquid phase—were calculated under different cooling rates, carbon content and temperature fluctuation amplitudes. The results showed that remelting between dendritic structures, unstable variation of interfaces between delta-gamma, and volume fractions variation of different phases happened when there was temperature fluctuation, which lead to uneven growth and stress concentration in the shell. These phenomena are especially serious in the hypo-peritectic steel casting processing. It is considered that the temperature fluctuation is one of the important reasons lead to strong crack sensitivity and difficult casting of the peritectic steels.

Key words: continuous casting peritectic transformation temperature fluctuation initial solidification
