Abstract: During directional solidification of multicrystaline silicon, solidification rate is an important parameter that affects the product quality, but it is difficult to measure directly. In this study, based on the thermal equilibrium in the thermal field of directional solidification furnace, a solidification rate calculation model was established and the effect of temperature on the solidification rate was studied. The results show that there is a regular change trend of temperature gradient ratio in liquid and solid phase during solidification .The theoretical value of solidification rate obtained by this model is in good agreement with the experimental value. It can provide support for the evaluation and regulation of the solidification rate during directional solidification of multicrystaline silicon.
