Determination of the liquid steel viscosity curves using a high temperature rheometer

Abstract

Rheological measurements of high melting temperature materials require specialist equipment, which allow to obtain high temperature inside. This situation take place in case of iron alloys. In literature there is lack of information about rheological properties of liquid iron solutions. This paper is intended to supplement the data in this regard; included in the study of iron solutions rheological properties: five chemical composition with carbon amount in the range between 0.39 - 0.89%, while used shear rate in the range between 40-180 s-1. Obtained viscosity values are set in the range between 0.002-0.018 Pa•s. The obtained results could be used for verification of the model which calculate the parameters of liquid iron alloys during casting, in which the viscosity is one of the mane parameter.
