“…As a result, more alumina (exceeding 15% in many enterprises) or titania (more than 10%) occur in the BF slag, resulting in higher viscosity, worse fluidity, and poor operational stability [4][5][6][7][8][9][10]. So it is essential to studying the viscous behavior of BF slag with more alumina (above 15%) or titania (above 10%) for optimizing the iron-making operation.…”

on the viscosity of high alumina and medium titania blast furnace slag was analyzed. An increase in CaO/SiO 2 ratio from 1.14 to 1.44 resulted in higher slag viscosity and break point temperature. They also increased with increasing Al 2 O 3 content but decreased with adding B 2 O 3 and Al 2 O 3 simultaneously at a fixed CaO/SiO 2 ratio of 1.14, which suggested that the effect of B 2 O 3 on viscosity and break point temperature is predominant compared to Al 2 O 3 . Apparent activation energies of CaO-SiO 2 -MgO-Al 2 O 3 -TiO 2 -B 2 O 3 slag were found to be between 74 and 169 kJ/mol.
