Simulation of Electromagnetic Field and Temperature Field in Microwave Sintering Cavity
As a new heating method,microwave heating is widely used in many fields including material sintering because of its incomparable advantages over traditional heating methods.However,the mecha-nism of microwave action on sintered materials is still unclear,and there is no sufficient systematic re-search on dynamic simulation and optimal design of microwave heating process,which limits the populari-zation and application of microwave sintering technology in a wider range.Therefore,the distribution of e-lectromagnetic field and temperature field of the high temperature layer,insulation layer and material in the microwave resonator are simulated,the dynamic changes of temperature and electromagnetic field of the material,high temperature layer and insulation layer in the microwave heating process are analyzed,and the effects of different sintering positions on microwave heating efficiency and uniformity are studied.By mastering the field distribution in the microwave sintering cavity,the suitable sintering position of the sample is found,and good sintering effect is obtained.
