摘要

Computer modelling using an FEM-based program, ie Forge 2008, was carried out. Laboratory modelling of the process of free hot forging in shaped anvils was conducted to close up metallurgical defects. Results obtained from the simulation modelling were processed by using a commercial statistical package, ie Statistica 60 PL. The influence of the anvil shape and main parameters of the forging process on closing up metallurgical defects were determined. On the basis of the investigation carried out, the optimal values of main forging technological parameters and suitable groups of anvils to be used in particular forging stages are proposed for the elimination of metallurgical defects.
