Abstract

The invention relates to continuous production equipment for a foam aluminum alloy. The continuous production equipment comprises a smelting heat-preserving furnace, a molten aluminum thickening furnace, a continuous foaming furnace, a rolling device and a cooling system, wherein the molten aluminum thickening furnace comprises an intermediate frequency furnace body I, a movable furnace cover and a stirring device; the intermediate frequency furnace body I is used for receiving molten aluminum flowing out of a chute; one side of the bottom of the intermediate frequency furnace body I is provided with a conveying valve bank which is connected with the continuous foaming furnace and is used for conveying thickened molten aluminum to the continuous foaming furnace; the conveying valve bank comprises a ceramic conveying tube, a high-temperature adjusting valve and an executing mechanism; the continuous foaming furnace comprises an intermediate frequency furnace body II, a furnace cover and a stirring device; the bottom of the intermediate frequency furnace body II is provided with a ventilation brick; a gas supplying device is arranged on the ventilation brick; one side of the upper part of the intermediate frequency furnace body II is provided with a foam aluminum alloy outflow port which is connected with at least two groups of movable furnace nozzles; molten aluminum foam in the furnace is conveyed to the rolling device through the movable furnace nozzles for molding by rolling. According to the continuous production equipment, the foam aluminum alloy is produced by adopting a continuous foaming and casting way, and foam aluminum sections of various sizes and various section specifications can be prepared.

Description

technical field [0001] The invention relates to metal smelting equipment, in particular to a continuous production equipment of foamed aluminum alloy. Background technique [0002] Foamed metal is a new type of porous engineering material with excellent physical properties and good mechanical properties developed rapidly in the late 1980s. The porous structure of foamed aluminum alloy has the functions of sound absorption, sound insulation, heat insulation, flame retardancy, and shock absorption. , absorbing impact energy, electromagnetic shielding and other characteristics, it has a very broad application prospect in many fields such as national defense and national economic construction, and has become one of the important research contents in the high-tech field of material science in the world today. [0003] In the preparation of foamed aluminum alloys, the current mature production processes include melt foaming method and infiltration method, which are mainly produced...

AI Technical Summary

Problems solved by technology

For example, the stirring force of the electromagnetic stirring method used is too small, and more pores cannot be obtained, and foamed aluminum alloys with different porosity cannot be produced; Production, but the high-temperature aluminum liquid introduced through the diversion hole cannot be quantitatively input, and the design of the vent pipe, such as the "L" type vent pipe, is difficult to manufacture, and it is often immersed in high-temperature aluminum liquid, which is easily blocked by aluminum corrosion and then fails
