Problems solved by technology

[0002] Due to the large number of voids inside foamed aluminum, it has light weight and high strength, and has the advantages of absorption, impact resistance, electromagnetic shielding, low thermal conductivity, etc. It has been widely used in rail transit, aerospace, military, automobiles, etc. In many fields, there are many preparation methods for running donkeys at present, such as direct melt foaming method and gas foaming method. At present, the direct melt foaming method is the most mature. The disadvantage is that its foaming rate is insufficient and the internal bubbles are uneven, which seriously affects the product quality. At the same time, with the wide application of foamed aluminum, the demand for it is increasing

Abstract

The invention provides an automatic continuous foaming formation type production technology process. The technology process is characterized in that molten aluminum is quantitatively transferred into a foaming bin after being foamed for the first time; nitrogen is charged, and thus the molten aluminum which is foamed for the first time and transferred into the foaming bin is foamed for the second time, wherein the temperature of the molten aluminum foamed for the second time is 750-900 DEG C; a casting die set is preheated during the processes of transferring and foaming the molten aluminum, and the preheated die set performs automatic casting while being transferred from a casting station to an output station; aluminum ingots which are respectively automatically output and cast through the die set subjected to the casting are cooled to the temperature of 200-300 DEG C and then output to the next process; a die conveying mechanism is used for controlling a plurality of production processes such as the processes of preheating of the die, secondary forming of the molten aluminum after the first foaming, die casting, and cooling of foamed aluminum, and all the production processes are automatic, so that the technological problems on increasing of the yield of the foamed aluminum and improving of the uniformity of the foamed aluminum and bubbles in the prior art can be solved.
