摘要
通过微型烧结试验研究了钛对烧结矿基础性能的影响。研究结果表明:钛对烧结矿影响较大。随着钛质量分数的升高,混合矿的连晶强度和同化性温度升高,而液相流动性和黏结相强度降低。钛在烧结过程中易与Ca O反应生成高熔点的钙钛矿,减少铁酸钙物质形成,改变烧结矿矿相结构,不利于矿粉之间结合。实际生产中,应该减少混合矿的钛质量分数,从而提高烧结矿质量。
The influence of titanium on the basic characteristics of sinter is investigated by mini-sintering and sinter pot test. The results show that titanium has a great influence on sinter. With the content of titanium increasing,the crystal in-tensity and the assimilation temperature of mixed ores rise,but the liquid phase fluidity and the binding phase strength de-crease. Titanium reacts with CaO to generate high melting point perovskite in sintering process and reduces the formation of calcium ferrite material,which changes ore phase structure of sinter and goes against the combination among mineral powder. During the production,reducing the content of titanium can improve the quality of sinter.
