| Abstract: | To improve thermal fatigue properties an improved mould was suggested based on thermal fatigue and simulated tests. Thermal stress changes in both the practical and the improved ingot moulds in the processes of casting steel and water bath were analyzed by the finite element method. The result shows that thermal stress is main reason to destroy the ingot mould. The effectiveness of the improved ingot mould was also explained. |
