【摘要】 在铁矿粉烧结过程中,铁矿粉与CaO反应生成的液相的流动特性,是衡量烧结混合料能否有效粘结的重要指标之一.采用微型烧结法和基于流动面积的粘度测量法,以10种常用进口铁矿粉为对象,研究其液相流动特性及其影响因素.分析了铁矿粉的液相流动特性对实际烧结过程的影响.结果表明:不同种类的铁矿粉由于其自身特性的不同,所生成的液相的流动能力及其随温度、碱度的变化规律有很大差异.更多还原

【Abstract】 In the sintering process of iron ores, the fluidity of sintering liquid phase created by iron ores reacting with CaO is one of the important indexes that evaluate whether the sintering mixture can consolidate effectively. 10 kinds of imported iron ore fines were used to investigate the fluidity of liquid phase in iron ores and analyze its influential factors by the minitype sintering method and the viscosity evaluation method based on flow area. The effect of the fluidity of liquid phase in iron ores on the realistic sintering process was discussed. The results indicate that different iron ores have different fluidities of liquid phase in sintering conditions due to their inherent characteristics.更多还原
