| Popis: |
Al–Ti-B grain refiners are used as a grain refining agents in twin-roll casting. Although Al3Ti particles in the rod dissolve, principal inoculant of TiB2 remains undissolved and initiate heterogeneous nucleation. TiB2 particles with higher density than liquid Aluminum are in tendency to settle as they are released from the melting grain refiner rod. Experimental studies showed that Ti concentration varies at different depth of the liquid metal in the launder. As samples were gathered from the bottom, not only the chemical content, but the metallographic analysis of the samples clearly exhibited that melt at the bottom of the launder heavily bear TiB2 particles and oxides. The trajectories of the particles upon revealing from different position of the depth and their settlement were also simulated in finite element analysis (FEA) and experimental findings were confirmed. |
