中高度烧损进口铁矿粉烧结性能试验研究

针对首钢矿业公司烧结厂中高度烧损进口铁矿粉的品种及数量不断增多的供应现状，为探索含铁原料变化对烧结矿生产、质量及成本等方面的影响规律，寻求科学合理的原料搭配比例，对现有原料结构条件下不同铁矿粉的同化温度、液相流动性等烧结基础特性进行了研究，并模拟烧结生产实际情况对不同品种的铁矿粉进行了实验室配矿烧结试验。通过试验，摸索出了各种进口铁矿粉的烧结性能及其合理的配矿比例范围，认为通过合理配矿，能够解决中高度烧损进口铁矿粉在烧结矿生产应用中的产品质量和经济效益等矛盾。

Experimental Research on Sintering Performances of Imported Powder Iron Ores with High and Medium Ignition Loss

In view of the increased varieties and quantity of the imported powder iron ores with high and medium ignition loss that are supplied to the Sintering Plant of Capital Steelg Mining Co. , to investigate the effect law of the change in iron - containing raw materials on the production, quality and cost of sintering ore and to seek for a scientifically rational raw material proportioning, study was made on the basic sintering characteristics such as assimilation temperature and liquid phase flowability of various powder iron ores under the existing raw material structure conditions. Laboratory ore blending and sintering test was also made on various powder iron ores by simulating the real production conditions. Through the tests, the sintering performances of various types of imported powder iron ores and the range of their rational proportioning ratio were found out. It is considered that the rational blending of ores can solve the contradiction between the product quality and the economic benefit in the application of imported powder iron ore with high and medium ignition loss in the production of sintering ore.
