Foamed aluminum production line based on blowing foaming

Abstract

The invention relates to the technical field of foamed aluminum production, in particular to a foamed aluminum production line based on blowing foaming, which comprises a smelting furnace, a foaming tank, a liquid storage tank and a molten aluminum transfer mechanism, a blowing unit is inserted into the foaming tank and used for filling gas into the molten aluminum to form bubbles, and a vertical cooling and lifting device is further arranged on the foaming tank and used for pulling the foam of the molten aluminum to the front; the liquid storage pool is arranged beside the foaming pool and communicates with the bottom of the foaming pool, a high-temperature radar liquid level meter is arranged above the liquid storage pool and used for monitoring the liquid level of molten aluminum in the liquid storage pool, and when the liquid level of the molten aluminum is lower than a low value, the molten aluminum in the smelting furnace is transferred into the liquid storage pool through a molten aluminum transferring mechanism; stopping until the high-temperature radar liquid level meter monitors that the liquid level of the molten aluminum in the liquid storage tank reaches a high level value; by means of the foamed aluminum production line, automatic liquid supplementing in the blowing method production process is achieved, manual liquid supplementing operation is not needed, and potential safety hazards are reduced.

Description

technical field [0001] The invention relates to the technical field of aluminum foam production, in particular to an aluminum foam production line based on air blowing and foaming. Background technique [0002] As an important branch of metal foam, aluminum foam is based on aluminum or aluminum alloy, and is a new type of material that combines structure and functionality with the improvement of production technology. And the development of the national economy, the application of aluminum foam in aerospace, transportation, construction engineering, machinery manufacturing and other fields is becoming more and more in-depth and extensive. In order to further reduce energy consumption in the production process of foamed aluminum, improve production efficiency, and ensure product quality and consistency, those skilled in the art have made unremitting efforts. [0003] At present, the blowing method is a relatively common method used in the production of foamed aluminum. It bl...

Problems solved by technology

[0004] However, in the existing production process of the blowing method, most of the pourable aluminum melting furnaces are used to replenish liquid to the liquid storage tank or directly to the foaming tank. Using this method to replenish liquid will result in excessive heat loss, and the aluminum liquid will be added The volume control is not accurate enough; the existing operation of replenishing liquid to the liquid storage tank or the foaming tank is manual operation, which is low in efficiency and poor in accuracy. Contact also brings certain security risks
