Accurate Viscosity Calculation for Melts in SiO<sub>2</sub>–Al<sub>2</sub>O<sub>3</sub>–CaO–MgO Systems

Abstract: The viscosity of SiO 2-Al 2 O 3-CaO-MgO system and its subsystems are of fundamental importance for control and optimization of metallurgical, material, energy and geological phenomena. In this work, an accurate and simple viscosity model suitable for use in numerical simulations was established for SiO 2-Al 2 O 3-CaO-MgO system and its subsystems, based on the physically meaningful MYEGA equation. The model was calibrated by 4403 viscosity data measured in non-graphite crucibles. It was found current model ca… Show more

“…blast furnace slags, metallic slags), and a good knowledge of slag and aluminosilicate melt properties is important to produce high quality mineral wool. The most important melt properties to be controlled during the fiberization process are density [4], surface tension [4], viscosity [6] and liquidus temperature [7,8]. Once fibers are produced, their quality is decided by their geometric features (distribution of diameter and length), as well as mechanical properties such as Young's modulus [9,10] and surface hardness [10] of fibers.…”

“…Technical works related to industrial 2 of 12 operations with added CaO and Al 2 O 3 are also available in the literature [10][11][12][13]. While there are indications of improvements in slag viscosity properties [14][15][16], systematic thermodynamic information related to the effect of CaO and Al 2 O 3 in the Cu 2 O-FeO x -SiO 2 system is at the moment not reported in the literature.…”

“…1) Over the past decades, abundant viscosity models have been developed, and the details and limitations of these models have been well documented. [2][3][4][5][6] In the previous work of Reddy et al, [7][8][9][10][11] a structure-based viscosity model was proposed to represent the viscosity of the silicate and borate systems. The present paper describes…”
