Simulation Analysis of Compaction Effect of Upsetting and Drawing on the Core of Back-up Roll
This paper simulates the forging and compaction process of the Back-up roll produced by 83T ingot,combines several upsetting and drawing tools for simulation of compaction process values while using the same process parameter to analyzes the equivalent strain and Q value of the core of the forging.The results show that most favorable equivalent strain and largest Q value of the core of the forging can be achieved by combining the hanging type upsetting disc and the 1500KD drawing tool,by using this method,better compaction can be achieved and core defects can be reduced.
