中文摘要

采用微波谐振腔微扰法测定碳质还原剂和锌窑渣混合物料的吸波特性，研究碳质还原剂配入锌窑渣不同比例时混合物的吸波特性与材料的复介电常数（ε″）、微波场内热源强度P(P=ωε″E2V)的关系。测试和分析结果表明，在粒度为147 ～175 μm条件下，通过比较复介电常数的大小确定了椰壳碳和锌窑渣最佳配比为18%，焦碳和锌窑渣最佳配比为28%，石墨和锌窑渣最佳配比为16%，在此配比条件下得到了ε″和P的最大值，并且3种碳质还原剂和锌窑渣混合物料的吸波特性发生了突变。

英文摘要

The microwave absorbing characteristics of the mixtures of carbonaceous reducer and zinc kiln slag were measured by the technique of microwave cavity perturbation and the relationships between P(P=ωε″E2V) and the microwave absorbing characteristic of the mixtures were studied. The results indicated that when the particle size of the mixtures is in the range of 147～175 μm, the optimal proportions are 18% (coconut’s carbon:zinc kiln slag),28% (coke：zinc kiln slag) and 16% (graphite：zinc kiln slag),respectively. Under those proportions, ε″ and P reach sharply to maximums and the characteristics of microwave absorbing of mixtures change.
