To check the application possibility of zircon grains for high Mn-high Al steel grades, laboratory experiments are carried out to investigate the sintering behaviors of the mixed filler sands of chromite and zircon grains. It is found that the mixed filler sands have a good sintering performance without the impact of liquid steel, and the sintering is continuously accelerated with the increase of zircon addition. During sintering, the zircon grains will decompose into zirconia and SiO2, and react with chromite grains to generate a liquid phase. Liquid steel enhances the sintering of the filler sands significantly, and the Mn and Al contents in steel play an important role. In case of high Mn-high Al steel grades, the effect of Mn on the sintering is more remarkable than that of Al, and the mixed filler sands are seriously sintered. Zircon sand grains are not suitable for high Mn-high Al steel grades.
