SIMULATION OF THE SEMI-FINISHED METALLIC MATERIALS THROUGH THE FINITE ELEMENTS METHOD

摘要

The development of expert programmes, which utilize in principal the finite elements analysis, simultaneously with the appearance of always stronger computers (from the point of view of the memory and computing speed) allows the tackling of numerous theoretical and practical problems, from which the heat and mass transfer in the metallurgical installations takes an important place.The paper treats the modalities in which such a system (Flux-Expert ) is applied in the simulation in the heating (with technological aim) of a semi-finished product with a given geometry and a set of a specific thermo-physical properties.For an easy understanding of the principles used in the system, a short analysis of the finite elements method in made.The heating of an individual part with a relatively simple geometry is made, in a furnace with a prevalently radiant heat transmission.The utilized heating process is the transitory one, the equations system being non linear.The optimal heating variant is bound with the possibilities of placing the semi-finished product in the precincts and the adopted heating regime.The variation of the temperature on the section, for a chosen time sample, offers a good criterion of comparison between the studied variants.
