Multi-furnace casting method for aluminum ingot, and chute assembly and casting equipment for implementing method

Abstract

The invention discloses a multi-furnace casting method for an aluminum ingot, and a chute assembly and casting equipment for implementing the method. The chute assembly comprises more than two main chutes connected between tap holes of corresponding mixing furnaces and casting production lines respectively, wherein the main chutes are sequentially connected through branch chutes; flow division structures are arranged at joints of the main chutes and the branch chutes; adjusting devices for adjusting the slopes of the branch chutes to change the flowing direction of diffluent molten aluminum in the branch chutes are connected to the branch chutes. Molten aluminum flowing out from any mixing furnace can flow to any casting production line, so that influence on the production efficiency of the aluminum ingot is eliminated; more importantly, the molten aluminum can continuously flow into any mixing furnace, so that aluminum block waste caused by casting interruption can be reduced; in addition, normal maintenance operation over other unused mixing furnaces can be reasonably and effectively scheduled, so that the mixing furnaces can be scientifically recycled, and the production cost is lowered.

Description

technical field [0001] The invention relates to a multi-furnace casting method for aluminum ingots and a chute assembly and casting equipment for implementing the method. Background technique [0002] In the aluminum electrolysis industry, the casting of aluminum ingot products is mainly realized by aluminum ingot casting equipment, and the aluminum ingot casting equipment is mainly composed of a mixing furnace, a chute assembly and a casting production line, and the chute assembly is the link between the mixing furnace and the casting production line The device, that is, the aluminum liquid flows out from the hole of the mixing furnace and enters the casting production line through the chute. [0003] Traditional aluminum ingot casting equipment generally has one furnace with one line, that is, one mixing furnace is connected to one casting production line. For foundry workshops, in order to improve production efficiency, there are more than two mixing furnaces in one found...

Problems solved by technology

In this case, if each casting production line is to be fully put into use, it must be ensured that each mixing furnace can be filled with molten aluminum in time, mainly because in the casting process, once there is a pause, it is easy to generate a large amount of waste aluminum blocks, both It causes waste and affects production efficiency. Moreover, if the delay is too long, the temperature in the mixing furnace will drop, and it is very troublesome to heat the mixing furnace. However, in the actual production process, it is difficult to meet the input requirements of all mixing furnaces. Liquid aluminum is required; more importantly, since each mixing furnace has to be shut down after a period of use and the slag is cleaned inside, otherwise the normal use of the mixing furnace will be affected. Once the furnace is shut down, the corresponding The casting production line cannot be put into use, which affects the production efficiency of aluminum ingots

Therefore, for aluminum ingot casting equipment with more than two mixing furnaces, the casting method of one furnace and one line cannot achieve a reasonable and effective recycling of each mixing furnace.
