Abstract: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 temperature. There is a linear relationship between solid fraction and stirring temperature. With increasing solid fraction, 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.
Key words: QTi3.5; electromagnetic-mechanical stirring; graphite particles; solid fraction
