Title:
活性金属の鋳造方法
Document Type and Number:
Japanese Patent JP7043217
Kind Code:
B2
Abstract:
In this casting method for an active metal, in an induction melting furnace (3) using a water-cooled copper crucible (2), a thin ingot (S) of an active metal is cast by tapping a melt M from a tapping hole (5) provided in a base section of the crucible (2) into a mold (4), wherein, when casting is performed under casting conditions in which the ingot has a diameter (D) of at least 10 mm, the ratio (H/D) of the height H of the ingot to the diameter D of the ingot is at least 1.5, and the weight of the melt M tapped in casting is no more than 200 kg, the temperature of the melt M during casting is set to be higher than the melting point of the active metal and casting is performed while the casting velocity V (mm/s), which is the velocity at which the casting advances in the mold 4, is controlled so that the relationship with the height H of the ingot satisfies V ≤ 0.1H by adjusting the opening diameter of the tapping hole 5.
