Abstract：During the process of microwave heating, the temperature distribution in a material submitted to microwave radiation is governed by interaction and absorption of radiation by medium, which accompany processes of transportion due to the dissipation of the electromagnetic energy into heat. A series of important factores which affect temperature-rising characteristic of carbon-containing chromite fines in microwave field are analysed in the paper. First of all , structure of resonance cavity for heating and multi permatron coupling mode affect the distribution of microwave field, combining with the variety of heat and physical properties such as specific heat and dielectric properties. The relationship between dissipation power of microwave and temperature can be solved by calculation, then the temperature-rising curve fitting of carbon-containing chromite fines can obtain by it. It is valid for temperature-rising characteristic of metallurgy material for microwave in similarity field structure with different material, proportioning and volume.
