Abstract
Computer modelling using an FEM-based program, Forge 2D®, was carried out in the study. Laboratory modelling of the process of free hot forging in shaped anvils was conducted to the closure of metallurgical defects.Results obtained from the simulation and laboratory modelling were processed by using a commercial statistical package, Statistica 6.0® PL. The influence of the anvil shape and main parameters of the forging process on closure of metallurgical defects were determined.On the basis of the investigation carried out, the optimal values of the main forging technological parameters of and suitable groups of anvils to be used in particular forging stages are proposed for the elimination of metallurgical defects.
