Embodiment Construction

[0015] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0016] like figure 1 Shown is the process flow chart of the foamed aluminum manufacturing method of the present invention. The raw material aluminum ingots are sent to the foamed aluminum production line, put into a heating pot, heated and melted, poured into the foaming box, and added into the foaming box. Paoji foaming--sent out by the conveyor belt after foaming, placed on the ground to cool naturally--cut into pieces according to customer requirements after cooling--after cutting, put them on a hydraulic press to compress to a certain height--according to customer specifications Edge trimming--packaging--completion, the foaming agent uses titanium hydride.

Abstract

The invention discloses a production method for foamed aluminum. The method sequentially comprises the following steps of: feeding an aluminum ingot serving as a raw material into a foamed aluminum production line; placing the aluminum ingot into a heating crucible; heating and melting the aluminum ingot and pouring the molten aluminum ingot into a foaming box; adding a foaming agent into the foaming box for foaming; conveying the aluminum ingot out by using a conveyor belt after the foaming is finished; placing the foamed aluminum ingot on ground and naturally cooling the foamed aluminum ingot; cutting the cooled aluminum ingot into slices according to requirements of a customer; placing the sliced aluminum ingot on an oil press to compress by a certain height; cutting edges according to the specification of the customer; and packaging the aluminum slices to obtain the foamed aluminum. Because a porous structure is adopted, the foamed aluminum has semi-permanent sound-absorbing performance, is made of metallic material, fire-resistant completely and is completely free from hazard of noxious gases; the porous structure can effectively absorb energy and has a remarkable energy-absorbing effect in high-impact deformation rate; and the foamed aluminum does not have toxicity or smell or produce dust, peculiar smell or harmful substances to human body such as arsenic acid and the like and can be completely recycled and prepared from waste aluminum.

Description

technical field [0001] The invention relates to a foamed aluminum noise reduction technology, in particular to a foamed aluminum production process, foamed aluminum and a noise-reducing sound-absorbing board. Background technique [0002] With the high speed of rail transit, the vibration and noise caused by train operation will become more severe, and the high-speed rail transit line will pass through many cities. Life, and even affect the normal operation of nearby schools, research institutes, hospitals, banks, etc. [0003] The experience of developing high-speed rail transit abroad shows that the application of vibration and noise reduction products can not only reduce the fatigue and wear of vehicles, tracks, and electrical equipment, reduce maintenance costs, but also reduce the impact of vibration and noise on residents and buildings along the line. To this end, we should actively learn from the successful experience of foreign countries, vigorously study the vibrat...
