对含碳铬铁矿粉在微波场中的升温特性作了分析。首先是分析加热谐振腔体的几何结构、耦合方式及物料的位置等来推测微波场分布，并通过实验进行了验证；进而分析了冶金化学反应的详细过程，结合含碳铬铁矿粉在微波场中的相关热及物理性质的变化，得出了在这个反应过程中物料的等效损耗因子；最后通过微波耗散功率与物料温度的关系的模拟计算，拟合出含碳铬铁矿粉的升温曲线。这种方法对于分析不同物料、不同配比、不同体积条件下在类似场结构下的微波冶金物料的化学反应过程中升温特性也是有效的。
Temperature rise characteristic of carboncontaining chromite fines during the process of reaction in microwave field is analyzed. Firstly, we predict the distribution of microwave by using structure of resonance cavity, multipermatron coupling mode and the position of the material during heating process, which is validated by experiment; then the detailed process of chemical reaction of metallurgy is analyzed, combining with the variety of heat and physical properties, the temperature inspired by dissipation power equation can be figured out in simulation, finally the fitting curve of temperature rise can be obtained. It is also valid for temperature rise characteristic of metallurgical material caused by microwave in similar field structure with different material, composition and volume.
