| Abstract: | Based on analyzing heat transfer mechanism in a roller-hearth furnace about to be created by a certain company,which is heated by radiant tube,a two-dimensional heat transfer mathematic model for slabs heating process was established.Then,computer numerical simu-lation system of slabs was developed,solved by TDMA numerical calculation method with alternative implicit pattern.Lots of numerical simulation calculations were done.Solutions from the simulation system lay theoretical foundation for on-line computer optimal control system of roller-hearth furnace,which will be put into operation. |
