Abstract
A method and apparatus for manufacturing an equiaxed crystal aluminum alloy cast ingot by using additive manufacturing and rapid solidification techniques are provided. The apparatus comprises: a metal heating mechanism and a negative pressure cooling mechanism. The metal heating mechanism is located above the negative pressure cooling mechanism and is connected thereto by a nozzle. The negative pressure cooling mechanism comprises a vacuum chamber having an air inlet hole and an air outlet hole, and a three-dimensional moving ingot mechanism disposed inside the vacuum chamber. The three-dimensional moving ingot mechanism comprises a moving ingot and a two-dimensional moving platform vertically connected to the moving ingot. A water cooling mechanism is disposed outside the moving ingot, and the moving ingot is driven by a precision motor to precisely move up and down.
