Influences of Electromagnetic Stirring Process Parameters on SiC Particle Distribution in Steel Matrix

Abstract:

SiC/Fe composite was prepared using electromagnetic stirring approach. The distribution of SiC particles in steel matrix was affected, in a different manner, by stirring power and stirring time in three test particle addition methods. When particles were blown from bottom of molten steel by airflow, the dispersion coefficient of particles was lower with reduced stirring power and prolonged stirring time. In contrast, when particles were dispersed directly by funnel or injected a block premade by particles and a small amount of matrix, the particle dispersion coefficient was increased following the decrease of stirring power or stirring time. This study provided a guidance of how to achieve a more uniform distribution of SiC particles in steel matrix.
