Abstract

The viscosities of CrO-containing slags obtained using high temperature equilibrium technique were measured by the rotating cylinder method at 1823 to 1948 K (1550 to 1675°C). The slag viscosity decreased with increasing CrO contents. CrO also exhibits a strong basic character in slags, and can act as a network modifier to depolymerize the slag network structure in CaO–SiO2-based slags. The dependence of the slag degree of polymerization (DOP) on the CrO content further validates these observations.
