Abstract

Carbon-bearing iron oxide pellets with the acid component of slag are rapidly heated and reduced in the temperature of 1623 K. The change of slag composition during the reduction is measured by the quantitative point analysis of EPMA. Viscosity of synthesized slag with as same as composition formed in the pellet are measured. The oscillating-plate viscometer is useful to measure the viscosity of slag with high FeO content.
