METHOD FOR CONTINUOUSLY CASTING HIGH PURITY ALUMINUM ALLOY

摘要

PURPOSE: To obtain a cast slab having fine and uniformized casting structure. ;CONSTITUTION: In a method for continuously casting an aluminum alloy which is solidified while rotating unsolidified molten metal by giving a rotary magnetic field generated with a rotary magnetic field generator 4 around the cast billet 6 during solidification to the unsolidified molten metal 5, the casting is executed in the conditions of 5-60Hz an alternate frequency for generating the rotary magnetic field, 6000-24000AT product of current (A) by the number of coil turns (T) and ≥0.2(H/D) ratio of a depth (H) in the unsolidified molten metal to a short side length (D) in the cast billet.;COPYRIGHT: (C)1995,JPO
