Viscosities of Blast Furnace Slags
Granulated iron blast furnace slags have been collected from ironmaking plants in Shougang.The viscosities of the industrial slags have been measured using the custom designed rotating bob apparatus which enables control of the gas atmosphere and rapid quenching of the samples on completion of the experiment.The experiments were carried out using Mo bob and crucible under ultra-high purity Ar flow.The microstructures and phase compositions in the quenched slag samples after the viscosity measurements were determined by Electron Probe X-ray Microanalysis (EPMA).The major chemical components of the iron blast furnace slag are A12 O3,CaO,MgO and SiO2 that account for over 95wt%.Corresponding synthetic slags made from these pure chemicals have been used to evaluate effects of minor components such as sulphur,MnO,TiO2 and FeO on viscosity of the iron blast furnace slags.It was found that the viscosities of the synthetic slags are significantly higher than that of the corresponding industrial slags.The difference in viscosity between industrial slags and synthetic slags will provide useful indications to apply the results of the synthetic slags to the real iron blast furnace slags.The present measurements are compared with available literature data and model predictions.
