Abstract

By using the finite element analysis method

temperature distribution and the heat transfer in the internal heating type multistage continuous vacuum furnace were analyzed as the theoretical basis for establishing the modeling.The ANSYS software was adopted to simulate the steady temperature field in vacuum furnace to obtain temperature distribution diagram of vacuum furnace and output value of the special nodes as theoretical modeling data.By measuring temperature of the special nodes in the vacuum furnace

the experimental data was extracted and compared with the simulated ones.The results show that the error of the model is less than 3.6%.
