Stirring slag scraping machine used for molten aluminum mixing furnace

Abstract

The invention discloses a stirring slag scraping machine used for a molten aluminum mixing furnace. The stirring slag scraping machine used for the molten aluminum mixing furnace comprises a base, a movable platform, a forward stretching mechanism and a stirring slag scraping mechanism; the movable platform is arranged on the base; the forward stretching mechanism is arranged on the movable platform; and the stirring slag scraping mechanism is arranged at one end of the forward stretching mechanism. The stirring slag scraping machine used for the molten aluminum mixing furnace is simple in structure, the slag scraping efficiency of the slag scraping machine is greatly improved, and shaking of the slag scraping machine in the slag scraping process is reduced to the maximum extent; and by means of stirring, dispersed slag in the molten aluminum mixing furnace is precipitated out, and high practicability is achieved.

Description

technical field [0001] The invention relates to the technical field of aluminum liquid mixed production, in particular to a stirring slag remover for an aluminum liquid mixing furnace. Background technique [0002] In the continuous production line of aluminum ingot casting, when producing aluminum ingots or aluminum rods, it is necessary to mix liquid metal aluminum with other metals in a certain ratio in the mixing furnace, and the furnace body in the mixing furnace itself contains slag, aluminum slag, Oxide and the bulk electrolyte carried when transferring the aluminum liquid produced by electrolytic aluminum, if these impurities are not removed in the mixing furnace, the quality of the aluminum ingot or aluminum rod will be affected, and the slag will also block the outlet of the aluminum liquid mixing furnace There are two ways to solve this problem, one is to reduce the slag at the source, and the other is to reduce the aluminum in the mixing furnace. Filter the liqu...

AI Technical Summary

Problems solved by technology

The existing method is to reduce the slag in the mixing furnace as much as possible by combining the two, but it is inevitable that oxides and slag in the mixing furnace itself will appear in the mixing furnace. , and to ensure precise operation, the technology is very difficult, the consumption of consumables is high, and the cost is high

Especially now, the sources of raw materials for molten aluminum are becoming more and more complex, and the amount of aluminum slag and oxide skin is increasing. How to reduce the slag in the mixing furnace has become a technical problem

In order to solve this technical problem, most enterprises have adopted a slag removal device while stirring the mixing furnace. However, the existing slag removal device firstly lacks the slag holding capacity of the slag removal head, which makes the slag removal efficiency of the slag removal device relatively low. Low, and the time to complete a slagging is too long, resulting in a rapid drop in the temperature of the mixing furnace, and correspondingly in order to keep the temperature in the mixing furnace at a certain level, it is necessary to increase the supply of electric energy or natural gas, thereby increasing reduce the consumption of energy; at the same time, the existing slag removing device cannot thoroughly clean up the slag in the molten aluminum, or the slag removing efficiency and effect of the existing molten aluminum mixing furnace are low, and the existing slag removing device is During the slag removal process, due to the large distance between the slag removal head and the supporting body of the slag removal device, the slag removal head tends to shake along with the mechanical movement of the slag removal device during the slag removal process, thereby displacing the The slag returns to the molten aluminum again, which seriously affects the slag removal efficiency and slag removal effect of the slag removal device
