CONTRIBUTIONS REGARDING THE PRODUCTION OF SOME C_(++) LANGUAGE SOFTWARE, BASED ON MATHEMATICAL MODELING OF SOME HEATING SYSTEMS FOR STEEL INGOTS WITH COLD INITIAL CONDITION

摘要

In this paper it is presented the mathematical modelling of a heating system for steel ingots put into furnace in cold condition. It is presented both the heat exchange in the furnace precinct and the heat transfer inside the metal. At the same time, it is designed in AUTOCOD the algorithm of achieving the C_(++) language software for the heat exchange mathematically modelled. It is aimed to get a closeness as high as possible between the imposed theoretical conditions and the industrial experimental conditions. Sums of Bessel -Fourier infinite strings as well as Bi, Fo and r/R criteria relations are used.
