Abstract：
The solidification process of P91 steel ingot with different riser heights was simulated.The distribution of shrinkage cavity was predicted by Anycasting software.For the accuracy of simulation,using the original process and optimize riser height after mould casting experiment,contrast examined the results of simulation and test results of shrinkage cavity defects.The results show that the riser height original mould casting process design could lead to ingot solidification shrinkage cavity defects are produced,after optimization of riser height can enhance the feeding effect of risers,prevent the shrinkage caused by solidification shrinkage of steel ingot the core production,significantly improve the performance of the steel ingot.
