[0002] Blowing foamed aluminum (also known as bubble aluminum or foamed aluminum alloy) is a process method for forming a porous foam structure by introducing a high-temperature gas into an aluminum melt. Common injection gases include argon, nitrogen, hydrogen, etc., and bubbles are formed in the aluminum matrix and obtain a stable pore structure upon solidification. This material has low density, good damping performance, and excellent specific strength. In the production process of foamed aluminum, the aluminum liquid produced by blowing is conveyed into the forming stage through a dedicated conveying system, which may use devices such as plunger pumps to achieve quantitative conveying of the aluminum liquid to ensure the consistency of the pore structure and mechanical properties of the foamed aluminum.

The equipment uses a simple crank linkage mechanism to achieve reciprocating motion of the horizontal gas outlet pipe, and uses an arc-shaped transition device to convert the aluminum melt foam from upward lifting to horizontal transmission. The process and equipment of the present application are simple, accurate in operation control, and can adjust the foam size formed in the aluminum melt by changing the reciprocating motion frequency of the gas outlet pipe, the pressure and flow rate of the compressed gas, or the diameter of the gas outlet micropore, thereby achieving the purpose of accurately controlling the pore size and density of the foamed aluminum product with high efficiency and low cost.
