| Abstract |
The solidification phenomena during the continuous casting of 150㎜ diameter billet was simulated by heat transfer analysis using the Crank-Nicolson method. The calculated results were compared with experimentally measured data. The mold cooling followed by the more powerful secondary cooling and the air gap formation during the continuous casting of free cutting brass can yield the wider dendrite arm spacing and the coarser lead particle size in the surface layer than in the core region. |
