  • The composites of 20%TiC/ZG270-500 were made by means of squeeze casting, and it's realizable for TiC particles getting into molten steel with the action of foam carrier. Then TiC particles motion behaviors in air gap and conditions for TiC particles getting into molten steel were investigated during the gasification and extinction of foam carrier. The experimental results show that TiC particle motion velocity increases with the increase of pouring temperature, filling velocity and cross-section ratio of exhaust orifice to metal cavity. There is a critical velocity that the TiC particle should exceed for getting into molten steel. The greater of TiC particle motion velocity, the easier for them getting into molten steel, and the more uniform distribution of TiC particles in steel matrix.
