摘要
本文探讨了微波加热在工业锡粉熔化中的应用。对离心雾化法制备的金属锡粉的形貌和粒径进行了表征锡粉颗粒均且呈球形，90% 的颗粒粒径为38~75 μm。过介电性能测试，研究了锡粉的微波吸收特性微波的穿作用对锡粉具有良好的整体加热能。温度高于150℃时，微波加热锡粉的主要机制是电导损耗设计开发了20 kW 微波熔炼锡合金装备，并将其应用于产业化该装备的加热率与常规方法相比能提高10 倍以上，缩短了熔炼工艺研究结果表明，微波加热加快了升温率，缩短了熔炼时间，锡回收率为97.79%，渣量仅为1.65%，其他损失低于0.56%；单位能耗仅为0.17 kW·h·kg−1远低于传统方法所要的能量。因此微波冶炼提高了加热效率，降低了能耗。
