Abstract

An array-jet large-size isometric aluminum alloy ingot additive manufacturing device and method are disclosed. The array-jet large-size isometric aluminum alloy ingot additive manufacturing device comprises a liquid aluminum spraying mechanism with array nozzles disposed in an atmospheric pressure chamber and a movable condensing mechanism located below the liquid aluminum spraying mechanism and arranged in a vacuum chamber and a control mechanism. The control mechanism sends an upward guiding command to a release mechanism and issues a three-dimensional movement command to the movable condensing mechanism, so that the aluminum liquid in the liquid aluminum spraying mechanism is sprayed to the surface of the movable condensing mechanism in a continuous array flow according to a preset pathand rapidly condensed to form an ingot. The array-jet large-size isometric aluminum alloy ingot additive manufacturing device has high production efficiency, and can prepare an oversized aluminum alloy ingot. The solidified structure is a full equiaxed crystal without macroscopic segregation.

Description

technical field

[0001] The invention relates to a technology in the field of metallurgy, in particular to an array spraying type large-size fully equiaxed crystal aluminum alloy ingot additive manufacturing equipment and method. Background technique

[0002] Semi-continuous casting is a method of manufacturing large-size aluminum alloy ingots routinely used in industry, mainly including two methods: one is hot top casting, and the other is direct chill casting. The advantage of hot-top casting is that the liquid level is stable during the casting process, but deep liquid pockets are formed in the center of the ingot, and the solidification structure contains a large area of ​​columnar crystal regions, and the macro-segregation from the center to the edge of the ingot is serious, and there is a high Internal stress remains, the ingot is easy to crack, and the yield is low, so it is not suitable for the production of aluminum alloy ingots with high alloy content. The advantag...
