Based on the knowledge to defects and advantages of traditional ingot casting, a new approach for casting of aluminum alloy ingot, based on heat conduction by rotating heat pipes, is put forward in this paper. Different from the conventional casting method that cooling around ingot, the microstructure and properties of casting ingots can be significantly improved due to cooling of molten liquid from the central by rotating heat pipes proposed by this paper. Through simulation on the working process and the fields of flow and temperature, it can be speculatively seen that the ingot solidification is from inside to outside and that inner stress inside the ingot is compressive. The influences of speed of heat pipe bundle, casting speed and casting temperature on the temperature field in the ingot have been systematically studied. The ingots with different sizes can be prepared by changing size and structure layout of the heat pipes.

Ingot Solidification

Abstract LESCALLOY UT-19 VAC-ARC is a premium quality carburizing steel with high hardenability. It is produced by vacuum are remelting (VAR) to provide a preferred ingot solidification and superior microcleanliness. It is used for aircraft gears, pinions and other carburized parts that require a high minimum core hardness. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness. It also includes information on corrosion resistance as well as forming, heat treating, machining, joining, and surface treatment. Filing Code: SA-394. Producer or source: Latrobe Steel Company.
