Round robin' project on the estimation of slag viscosities
Scandinavian Journal of Metallurgy, 2001
A ''round robin'' project has been carried out to determine the accuracy and reliability of various models used to estimate the viscosities of industrial slags. The 21 participants were divided into measurement suppliers and modelling participants. Reference materials were issued to the measurement suppliers to check the validity of the viscosity data supplied. A data base of viscosity-temperature-composition data was established for 8 different categories of slags. Chemical compositions were issued to the different modelling participants and the predicted viscosities were compared with calculated values. For mould fluxes, the

Effect of CaO/ SiO 2 ratio on viscosity and structure of slag
Metalurgija, 2015
L. Řehackova, S. Rosypalova, R. Dudek, J. Dobrovska, J. Kukutschova, VSB-TU Ostrava, FMMI, Ostrava, Czech Republic The objective of this work is experimental determination of temperature dependences of viscosity of the molten CaO Al2O3 SiO2 system and assessment of impact of CaO/SiO2 ratio on viscosity and structure of this system. Experimental measurements of viscosity were performed with use of the high-temperature viscometer Anton Paar FRS 1 600. Viscosity was measured in a rotational mode during heating at the rate of 3,3 °C/min in the temperature interval from 1 673 to 1 873 K. Viscosity in the molten oxide system is determined by the internal structure. Exact clarification of the change of structure of the oxide system caused by the increased content of CaO was performed by Fourier transform infrared spectroscopy.
Concepts and measurement of velocities and viscosities at the slag-metal Interface
2012
Dynamic studies on the mass transfer of surface-active elements from gas to molten iron through a suitable slag phase were carried out using sessile drop technique incorporating an x-ray imaging system. The surface active elements in focus were sulfur and oxygen using the slag systems CaO-SiO2-Al2O3-FeO and CaO-SiO2-Al2O3 respectively. In both cases, the slag was saturated with alumina in order to prevent any slag compositional changes due to reactions with the alumina crucible. Proper sulfur and oxygen potentials were maintained in all phases for both cases. X-ray videos were taken that were later processed to identify the oscillation of the molten iron drop occurring during the mass transfer. The oscillations were traced to the surface movement occurring due to the concentration difference of sulfur/oxygen at the interface, which created an instantaneous area change at the slag–metal interface. This area change was due to the combined effect of Marangoni flow and interface dilatat...

Metallurgical and Materials Transactions B, 2007
The viscosities of high alumina blast furnace slags were experimentally determined by the rotating cylinder method using the Brookfield digital viscometer model LVDV-II+ pro. Two different slag systems were considered for the current study, the CaO-SiO 2-MgO-Al 2 O 3 quaternary and the CaO-SiO 2-MgO-Al 2 O 3-TiO 2 quinary system. Experiments were conducted in the temperature range of 1650 to 1873 K. The effects of temperature, basicity, TiO 2 , and silica activity of slags on viscosity were studied. The viscosity decreases with basicity for high alumina blast furnace slags with basicity in the range of 0.46 to 0.8. At high basicity (~0.8), slag viscosity decreases even with a small amount of TiO 2 (~2 pct) addition in the slag. With an increase in silica activity in the range of 0.1 to 0.4, the slag viscosity increases, the increases being steeper below the liquidus temperature.
Characterization and evaluation of the hydraulic activity of water-cooled slag and air-cooled slag
Cement and Concrete Research, 2001
Water-cooled slag (WS) and air-cooled slag (AS) were characterized chemically and mineralogically and a comparative study of their reactivities with 10% and 20% lime was conducted using an accelerated chemical method. Both types of slag have the same chemical composition, but WS is completely vitreous materials and the main mineral composition of AS is gehlenite. The kinetics of the WS–lime and AS–lime reactions were investigated in suspension by the determination of the proportions of unreacted lime and the combined water up to 28 days. Both slags underwent hydration at room temperature. The rates of hydration were rapid in the first 3 days, but subsequently it depressed due to the formation of dense layer of hydration products on the unhydrated slag grains. The hydration products were identified by X-ray diffraction (XRD) and SEM combined with EDX. The hydration products formed depend on the lime contents. The results obtained suggest that AS may be used in the production of low strength building units or may be used with WS in the production of slag cement.
Some fundamental aspects of the dry slag granulation process
There is a growing interest in development of a dry slag granulation (DSG) process so as to recover the sensible and latent heats from molten slags and convert iron blast furnace slags into a glassy phase that is a suitable replacement for Portland cement. The combination of waste heat recovery and conversion of slag into a saleable product could result in significant reductions in waste and emissions associated with production of steel and cement. The present paper covers some of the fundamental aspects of the reactions taking place during dry granulation of molten slag. In particular, the cut in sulphur emission from slag during DSG as compared with conventional wet granulation process and the dynamics of slag droplet collision with solid surfaces will be covered.
