Production system for continuously manufacturing foamed aluminum through gas foaming method

Abstract

The invention relates to a production system for continuously manufacturing foamed aluminum through a gas foaming method. The production system for continuously manufacturing the foamed aluminum through the gas foaming method comprises a heat preservation bin, a nitrogen supply station and a preheating chamber and further comprises a conveying mechanism, a foaming mechanism and a control mechanism, wherein the conveying mechanism linearly conveys a mold group arranged on the upper side of the conveying mechanism and a connecting assembly used for controlling output of the heat preservation bin and the gas supply station, the foaming mechanism is used for secondary foaming of molten aluminum, and the control mechanism is used for controlling all steps to be operated in order. In the secondary foaming process of the molten aluminum, the staying time of gas in the molten aluminum is prolonged, so that the foaming rate is improved, the loss of nitrogen is reduced, the foaming period is shortened, and therefore the production efficiency is improved; in the operation process of the conveying mechanism, all the steps are controlled to operate in order according to the movement displacement of the conveying mechanism, and the automatic production process of the foamed aluminum ingots is formed. The production system for continuously manufacturing the foamed aluminum through the gas foaming method has the advantages of being simple in structure, high in foaming efficiency, uniform in foaming, controllable in quality, efficient in production and environmentally friendly and saving energy.

Description

technical field [0001] The invention relates to the field of foamed aluminum production, in particular to a production system for continuously preparing foamed aluminum by a gas foaming method. Background technique [0002] The application of aluminum continues to increase due to its low density, high stiffness, corrosion resistance and good formability. This trend is particularly evident in the automotive industry, household appliances and construction industries, where there is a huge demand for aluminum with complex shapes and high strength. However, the production equipment and system of foamed aluminum in the prior art have the defects of uncontrollable foaming, discontinuous production, low production capacity, high energy consumption, high production cost and cumbersome process, the qualified rate of products is low, and the production There are many problems such as low safety factor. [0003] A foamed aluminum production system disclosed in Chinese invention paten...

Problems solved by technology

[0004] The technical solution disclosed in the above technical solution mainly integrates the various process sections in the traditional aluminum foam production process. Compared with the traditional production process, it aims to form a continuous production process; its shortcoming is that the entire production equipment The structure is complex, the unit output of aluminum liquid is realized by the original crucible dumping method, its production efficiency is low, and the foaming process is simply realized by a foaming furnace, and the foaming effect is difficult to control, so the above technical scheme exists, and the equipment structure is complex , low production efficiency and uncontrollable quality of foamed aluminum
