Continuous casting rods of aluminum alloy, casting method of continuous casting rod, continuous casting equipment

摘要

PROBLEM TO BE SOLVED: To provide a continuous casting apparatus with which an aluminum alloy-made continuously cast bar is cast, the continuously cast bar having excellent machinability and forgeability by mostly comprising columnar crystal and/or granular crystal while suppressing the production frequency of plumose crystal in the longitudinal direction of the continuously cast bar and by uniformizing unevenness of crystal grain diameters.;SOLUTION: In the continuous casting apparatus for casting the continuously cast bar from molten aluminum alloy 255, a vibration-giving device 411 which imparts mechanical vibration to molten aluminum alloy near the solidification surface via the solidification surface of the cast bar 1 from the surface of the cast bar 1 during the casting, is arranged.;COPYRIGHT: (C)2011,JPO&INPIT
