摘　　要：以酸溶性钛渣为原料,探讨酸溶性钛渣在微波场中的升温特性,通过对酸溶性钛渣进行微波加热及保温处理,考察在不同微波加热温度及保温时间条件下,对酸溶性钛渣微波改性后样品二氧化钛品位及硫、碳含量的影响。结果表明:提高微波加热温度与增加保温时间,有利于物料在微波场中氧化更加彻底,低价钛与铁及铁的氧化物的氧化反应使得总量增加而二氧化钛含量相对下降,同时也实现了酸溶性钛渣在微波场中较高的脱硫率与脱碳率。The laboratory investigation on temperature rising characteristics of acid soluble titanium slag in microwave field were carried out in different microwave heating temperature and holding time. The grade of titanium oxide and content of carbon and sulfur in the treated samples were regarded as significant test indexes. The results indicated that improving microwave heating temperature and increasing holding time were beneficial for the oxidation reaction of low valence titanium composition and iron oxide. Though the total mass of reaction product increased, the content of TiO2 in product relatively declined. In the meantime, high rate of desulfurization and decarbonization of acid soluble titanium slag was achieved in microwave field.
