摘要
The method and apparatus for manufacturing an equiaxed aluminum alloy ingot by additional manufacturing and rapid solidification include a metal heating mechanism and a negative pressure cooling mechanism, and the metal heating mechanism is located above the negative pressure cooling mechanism, and the nozzle ( It is connected to a negative pressure cooling mechanism via 5), and the negative pressure cooling mechanism is installed inside a vacuum chamber (8) provided with a gas entry hole (12) and an exhaust hole (13) and inside the vacuum chamber (8). The three-dimensional moving ingot mechanism has a moving ingot (18) and a two-dimensional moving table (10) connected in a direction perpendicular to the moving ingot, and the moving ingot has a moving ingot mechanism. A water cooling mechanism is installed on the outside of (18), and a precision motor (11) drives the moving ingot (18) so as to be accurately displaced up and down. By using a means of injecting a liquid instead of spray forming, the denseness of the alloy ingot is improved, oxidation is reduced and the production efficiency of the ingot is improved, and the non-macroseparable aluminum having an equiaxed crystal structure is used. And its alloy ingots can be manufactured rapidly. [Selection diagram] Fig. 1
