在铁矿粉烧结过程中，需要充分把握铁矿粉的烧结行为和作用，考察其同化性、液相流动性、黏结相自身强度、连晶固结强度等烧结基础特性，有助于企业通过烧结优化配矿有效使用铁矿粉资源。近年来，国内外在铁矿粉烧结理论和技术方面取得了长足的进步，尤其体现在低温烧结、厚料层烧结技术的发展、褐铁矿使用技术的完善、预还原烧结的开发、镶嵌式烧结的设计、高温特性研究的不断深入等方面。这些技术的创新主要围绕如何高效利用铁矿粉资源进行，通常是源于资源的劣化和环境的恶化。然而，铁矿粉的优与劣其实是相对的，通过发挥其优势、抑制其劣势的方式，使得这种矿从劣质变为相对的“优质”，并通过这些新技术使其优点凸显、缺点被弥补，那么该矿的使用量、技术指标就能得到提高，也就具有“优”的品质。通过这些研究，实现了对劣质铁矿粉资源的高效利用。本文对此进行综述。

The quality of the sinter influences its behavior in the blast furnace and the technical parameters of the blast furnace. The quality and the properties of the sinter are mainly determined by the properties of the iron ore powder. In recent years, the iron and steel industry faces with increasing cost pressures, as the quality of the powder iron ore deteriorates and its price increases. Meanwhile, an important progress is made in the technology of the iron ore sintering, especially in the development of the low temperature sinter and high-depth sinter, the improvement of limonite technology, the design of pre-reduction sintering and Mosaic Embedding Iron Ore Sintering (MEBIOS), and the improvement of high temperature properties of iron ore sintering, which will be briefly reviewed in the present paper. These technologies are aimed for more efficient use of the iron ore powder resource, related with concerns for resource degradation and environmental deterioration. The quality of ore is only a relative concept - a "low" quality ore can become relatively "high" if its strengths are exploited and weaknesses suppressed. These new technologies can reduce the consumption of ore and improve the quality of the final product, which are characteristic of a "good" ore, which means the efficient use of inferior resources.
