Description

Technical Field

[0001] The invention relates to the technical field of aluminum processing equipment, and in particular to a powder adding device in an aluminum liquid furnace. Background Art

[0002] The main purpose of adding powder into the aluminum liquid furnace is to improve the smelting process. Specifically, adding coal powder, silicon powder, etc. can act as a reducing agent to react with alumina in aluminum ore, reduce the smelting temperature, accelerate the reaction speed, improve production efficiency, reduce energy consumption, and improve the quality of aluminum liquid. The addition of refractory powders such as non-stick aluminum castables can enhance the corrosion resistance of the furnace lining, extend the service life of the furnace body, and ensure the quality of aluminum liquid. In the process of adding powder, usually an inert gas is used as a carrier to send powdered flux into the aluminum liquid furnace. In the powder spraying and refining process of the aluminum liquid furnace, the furnace mouth of the aluminum liquid furnace needs to be opened. An overly large furnace mouth will cause the heat of the aluminum liquid furnace to dissipate faster, while a smaller furnace mouth is prone to the phenomenon that the powder spraying mechanism cannot be inserted. Therefore, in the process of adding powder, it is necessary to dynamically adjust the size of the furnace mouth opening according to actual conditions. The existing powder adding equipment generally has a fixed powder adding range and cannot be adjusted. Therefore, the present invention proposes a powder adding equipment in an aluminum liquid furnace to solve the problems existing in the prior art. Summary of the invention
