Abstract
To control the shear property of a calcium silicate mold flux, we incorporated carbon (C) into it in the form of SiC. We measured the flux's viscosity using a rotationary viscometer to quantify its shear-thinning behavior and analyzed its structure to determine its degree of polymerization. Silicon carbide had the strongest shear-thinning property at C content = 1 wt pct and had the highest shear-thinning property ever achieved in a mold flux. The degree of shear-thinning property for silicon oxy-carbide glass followed the Oswals-De Waele power law model. This mold flux will improve the quality of continuously-cast steel by providing appropriate lubrication between the mold wall and the steel shell.
