This paper presents a finite element model for describing the temperature field of heat treatment furnaces. In the model, such complicated nonlinear factors as boundary conditions, physical properties and radiation etc. are considered. Based on the model, the three dimensional nonlinear FEM analysis system MARC is used to simulate the temperature field of 72 kW pit-type carburizing furnace, where an incremental iteration method is also used. The computer simulation results are well consistent with those of measurements. The work provides an excellent method for the virtual operatioin of heat treatment furnaces. It may become one of the core technologies of intelligent heat treatments.
