The purpose of the present research is to investigatethe slag-forming processes in a 11 M~3 blast-furnace smelting Pao-Tou iron ore. Petrographical examinations supplemented by White test studies show that the chief mineralconstituents present in the primary slag are calcium oxide, fluorite and wustite. From a comparison of the slag-forming processes in a 11 M~3 blast-furnace smelting Pao-Touiron ore with that smelting an ordinary acid ore, a new mechanism for the formation of theprimary slag in smelting the former ore has been proposed. In addition, it has been found thatthe plastic region in smelting Pao-Tou iron ore is smaller than that in the usual case, thereby,considerably facilitating the driving of the blast-furnace by improving the penetrability of thecharge column.
