摘要

The hot-top EMC (electromagnetic casting) method was put forward, namely, the shape of top liquid column was formed by the hot-top in the screen and the semi-suspended liquid column was formed by the electromagnetic force nearby the liquid-solid interface frontier. Using the numerical simulating technique, the temperature distribution was discussed, the effect of parameters such as upper-conduct distance (UCD), cool ing water rate of flow, pouring temperature and liquid column height on casting velocity were studied, the relationship among them was confirmed finally. According to the calculated results, the hot-top EMC shaping system was designed and a lot of experiments were performed. The pure Al thin slabs of 480 mm × 20 mm × 850 mm were made successfully. The result showed that the casting velocity curve obtained experimentally almost coincides to the calculated one.
