CASTING PROCESS FOR CONTINUOUS CASTINGS

摘要

In a process of withdrawing castings while vertically oscillating a mold formed with long side walls and short side walls in vertical continuous casting, the long side walls are separated from the castings by operating a hydraulic cylinder 4 in the time zones for which the castings are applied with a large frictional force. On the contrary, the separated long side walls are made close to the castings in the other time zones for which the castings are not applied with the large frictional force. By repeating the separation and approaching of the long side walls, it is possible to obtain the castings reduced in the depths of oscillation marks and suppressed in segregations at oscillation mark trough portions.
