| Abstract: | This paper introduces an applying software package based on the numerical simulation for calculating the temperature field of no-head ingots′solidification processes and predicting the porosity and shrinkage cavity.In terms of the quality cases of produced ingots and their according forgings the software was proced to be reliable by comparison with computed results.The influence of some technological parameters on the inherent quality of no-head ingots was analyzed and an optimized technological scheme was put forward. |
