HOT CHAMBER CASTER FOR ALUMINUM ALLOY

WIPO Patent Application WO/2015/068757

A1

[Problem] To provide a hot chamber caster for an aluminum alloy in which the casting speed is high and the problem of melting damage to the internal mechanism does not occur even when molten aluminum alloy is used. [Solution] A molten metal injection main cylinder part (120) made of ceramic is provided in a melting furnace (110). A valve body (150) is provided in the molten metal injection main cylinder part (120) at a position lower than that of an injection path (130). Application and removal of gas pressure of a predetermined pressure in an internal space (123) in the molten metal injection main cylinder part (120) is controlled by a pressurizing unit (160). When the pressurizing unit (160) applies the gas pressure, the valve body (150) moves in a closing direction, and the molten metal in the molten metal injection main cylinder part (120) is die-cast from the injection path (130) into a die (200). When the pressurizing unit (160) removes the gas pressure, the valve body (150) moves in an opening direction, and the amount of molten metal necessary for the next die-casting is fed into the internal space (123).
