QTi3.5 10graphite(mass fraction,%) slurry was prepared using electromagnetic mechanical stirring technology. The distribution of graphite particles in QTi3.5 10graphite slurry was studied using cold quenching method. The results show that solid fraction of QTi3.5 10graphite slurry increases with the decreasing stirring tern perature. There is a linear relationship between solid fraction and stirring temperature. With increasing solid frac tion, the rising of graphite particles in slurry is restricted gradually. When the solid fraction is larger than 42.5%, the rising of graphite particles in slurry can be controlled, and QTi3.5 10graphite slurry with uniform distribution of graphite particles can be prepared.
