Abstract

Based on the principle of downward continuous unidirectional solidification in the preparation of thin-walled copper tube

the physical and mathematical models of one-dimensional steady heat transfer for temperature field were established by analytical method. The effects of main parameters on the whole temperature field and solid-liquid interface and its mechanism were comparatively analyzed by combining calculated results with experimental data. The reasonable parameters were calculated under the condition of the highest casting speed in the limitation of existing processing parameters.
