Title:
DEVICE AND METHOD FOR TREATING A MELT WITH HIGH SHEAR AND STRONG ELECTROMAGNETIC STIRRING
Document Type and Number:
WIPO Patent Application WO/2017/113520
Kind Code:
A1
Abstract:
Provided are a device and method for treating a melt with high shear and strong electromagnetic stirring. The device is mainly composed of a crucible (4), a core rod (5) installed within the crucible (4), and an electromagnetic stirring device installed outside the crucible (4). The electromagnetic stirring device comprises a water tank (1) and an electromagnetic stirrer (3) placed in the water tank. The shape of the crucible (4) is semi-conical or cylindrical. The shape of the core rod (5) is a semi-conical or cylindrical structure at the upper end and a spiral structure at the lower end. The centre of the core rod (5) is a hollow structure, with the shape thereof being semi-conical or cylindrical. The core rod (5) and the crucible (4) are coaxial. The device can be used for treating an alloy melt, such as an aluminium alloy, a magnesium alloy, a copper alloy, a zinc alloy and a titanium alloy, and a particle-reinforced metal based composite material thereof. The temperature field and ingredient field of a metal melt treated by the device are very uniform, and a moulded blank and parts have fine and uniform textures, uniformly distributed ingredients, reduced casting defects and improved properties.
