Trial Production of Disk Caster for Thin Bar

In this study, a disk caster to cast thin bars was proposed and assembled, and the test casting of thin bars was carried out. The disk caster consists of a casting disk, a dam disk, and a tundish. A groove was machined on the side of the casting disk and, enclosed by the dam disk, acted as a mold in which to cast the bar. The diameters of the casting and the dam disks were 600 and 400 mm, respectively, and the cross-sectional area of the groove was 59.5 mm2. The casting speed was varied from 4 to 10 m/min. Molten Al–5%Mg was poured into the groove from the tundish. The groove was filled by the molten metal, and the bar could be cast continuously. The effect of the rotation speed of the dam disk on the casting of the bar was investigated.
