Aluminum ingot and aluminum scrap double fusion system alloy furnace

Abstract

The invention discloses an aluminum ingot and aluminum scrap double fusion system alloy furnace. The furnace comprises a fusion furnace body, and an aluminum scrap fusion pool, an aluminum ingot fusion pool and a double mechanical stirring system which are positioned behind the fusion furnace body; and the double mechanical stirring system comprises an aluminum scrap stirring system and an aluminum ingot stirring system, the aluminum scrap stirring system is connected with the aluminum scrap fusion pool, and the aluminum ingot stirring system is connected with the aluminum ingot fusion pool. The aluminum ingot and aluminum scrap double fusion system alloy furnace can realize simultaneous fusion of aluminum scraps and aluminum ingots, makes the aluminum scraps, aluminum ingots and an aluminum liquid in the fusion furnace body form double annular cycle, avoids the abuse of multi-time opening of a furnace door for adding aluminum ingots and removing slag in the alloy aluminum melting process, reduces heat loss in the fusion furnace, avoids impact of frequent opening of the furnace door on a refractory material nearby the furnace door, prolongs the service life of the refractory material nearby the furnace door, reduces wastes of the raw material industrially-pure aluminum and the cost investment, reduces the labor intensity of workers in high temperature environment, and creates comprehensive values and benefits for aluminum alloy production enterprises.

Description

technical field [0001] The invention relates to the technical field of aluminum alloy production and processing, in particular to an alloy furnace with a double-melting system for aluminum ingots and aluminum chips. Background technique [0002] At present, in the process of secondary processing and alloying of aluminum in aluminum smelting enterprises, when aluminum ingots are added to the melting furnace for alloying, they need to use forklifts to add aluminum ingots to the melting furnace in batches, and use burners in the melting furnace to heat and melt In this process, the flame of the burner directly heats the aluminum ingot, causing a large area of ​​aluminum products to be burned, and the oxidized slag inclusion is very serious. It is necessary to open the furnace door regularly and add a slag cleaning agent to clean the molten liquid in the furnace. , the slag removal process lasts for a long time, resulting in a large amount of heat loss in the furnace; in addit...

Problems solved by technology

[0002] At present, in the process of secondary processing and alloying of aluminum in aluminum smelting enterprises, when aluminum ingots are added to the melting furnace for alloying, they need to use forklifts to add aluminum ingots to the melting furnace in batches, and use burners in the melting furnace to heat and melt In this process, the flame of the burner directly heats the aluminum ingot, causing a large area of ​​aluminum products to be burned, and the oxidized slag inclusion is very serious. It is necessary to open the furnace door regularly and add a slag cleaning agent to clean the molten liquid in the furnace. , the slag removal process lasts for a long time, resulting in a large amount of heat loss in the furnace; in addition, during this process, a large amount of aluminum liquid will adhere to the slag removal tool, and will be taken out of the furnace with the reciprocating slag removal. The molten aluminum needs to be recycled twice, and the recycled aluminum needs to be smelted again, which increases the cost and causes a great waste of manpower and material resources

[0003] In addition, the smelting and feeding process must be carried out manually by a forklift, which is very dangerous. Opening the furnace door at the same time will cause heat loss again, and the addition of aluminum ingots will increase the temperature difference of the molten aluminum in the furnace, resulting in over-burning. Further increase the burning loss of raw materials; in addition, when the furnace door is opened, it is impacted by cold air, and the refractory materials near the furnace mouth are vulnerable to functional damage
