本文叙述了炼铁原料物理结构研究的意义,介绍了有关物理结构测定的方法-水银测孔仪。文中引述了作者所做的部分铁矿石、烧结矿与球团物理结构实验结果,讨论了多孔固体原料按气孔半径大小分布的总表面积与还原性能的联系,指出炼铁原料物理结构研究在还原动力学理论研究工作中的作用。 This article describes the significance of the research on the physical structure of raw materials for iron making, and introduces the method of measuring the physical structure - the mercury porosimeter. In this paper, some experimental results of the physical structure of iron ore, sinter and pellets made by the authors are introduced. The relationship between the total surface area of ​​porous solid material distributed according to the stomatal radius and the reduction performance is discussed. It is pointed out that the physical structure of raw material for ironmaking The role of motivation theory in research work.
