Observation of the reactions between iron ore and metallurgical fluxes
网页2021年7月16日The lime and BOF slag have similar levels of molten iron ore at 1400°C with results of 32% and 34%, respectively, while limestone had a significantly higher result of 64% liquid material. Lime and BOF slag gained very similar liquid percentage however, the nature of the liquid fraction and its dispersion throughout the samples differ greatly.

Steelmaking Process an overview ScienceDirect Topics
网页During the steelmaking process, fluxes that consist of lime (CaO) or dolomitic lime, with iron and scraps, are charged to the furnace. There is a certain amount of free lime (f-CaO) in steel slag. Free lime, with a specific gravity of 3.34, can react with water to produce Ca(OH) 2,with a specific gravity of 2.23, which results in volume increase ( Fig. 9.1 ).
