Spinning properties of slag fiber according to viscosity model

Abstract

Slag means residues that occur during the steelmaking process. Measuring the high temperature viscosity of the slag is difficult and high cost. So, viscosity models can be used to predict the trends in viscosity as a function of the key variables, and so assist in the selection of process conditions and the optimization of the performance of slag fibers. Slag fibers with compositions similar to glass/carbon fibers are also expected to be suitable for spinning at a log viscosity value of 2.8–3. The fiberizing temperature of glass fiber is more than [Formula: see text] and the fiberizing temperature of basalt fiber is more than [Formula: see text], while the slag fiber can be spun at a low temperature.
