Embodiment 1

[0040] A cleaning method for an aluminum alloy dry cleaning furnace, mainly comprising the following steps:

[0041] Step 1. Wash the furnace for the first time

[0042] Put the aluminum ash with a furnace group capacity of 1.2‰ into the hearth of the dry cleaning furnace for the first furnace cleaning, stir and spread the aluminum ash evenly with a stirring rake, keep the temperature at 875°C, and keep the temperature for 2 hours; use a stirring rake to clean the furnace Stir evenly around to make the slag absorb the aluminum liquid precipitated in the furnace, and immediately remove it after stirring.

[0043] Step 2, the second furnace washing

[0044] Put the aluminum ash with a capacity of 0.75‰ of the furnace group into the furnace of the dry cleaning furnace for the second furnace cleaning, stir and spread the aluminum ash with a stirring rake, and keep the temperature at 825°C for 2 hours; use a stirring rake to clean the furnace Stir evenly around to make the slag a...

Embodiment 2

[0051] A cleaning method for an aluminum alloy dry cleaning furnace, mainly comprising the following steps:

[0052] Step 1. Wash the furnace for the first time

[0053] Put the aluminum ash with a capacity of 1‰ of the furnace group into the hearth of the dry cleaning furnace for the first furnace cleaning, stir and spread the aluminum ash evenly with a stirring rake, keep the temperature at 900 ° C, and keep the temperature for 2 hours; use a stirring rake to clean the furnace Stir evenly around to make the slag absorb the aluminum liquid precipitated in the furnace, and immediately remove it after stirring.

[0054] Step 2, the second furnace washing

[0055] Put the aluminum ash with a capacity of 1.0‰ of the furnace group into the furnace of the dry cleaning furnace for the second furnace cleaning, stir and spread the aluminum ash with a stirring rake, keep the temperature at 850°C, and keep the temperature for 2 hours; use a stirring rake to clean the furnace Stir even...

Embodiment 3

[0062] A cleaning method for an aluminum alloy dry cleaning furnace, mainly comprising the following steps:

[0063] Step 1. Wash the furnace for the first time

[0064]Put the aluminum ash with a capacity of 1.5‰ of the furnace group into the hearth of the dry cleaning furnace for the first furnace cleaning, stir and spread the aluminum ash evenly with a stirring rake, and keep the temperature at 850°C for 2 hours; use a stirring rake to clean the furnace Stir evenly around to make the slag absorb the aluminum liquid precipitated in the furnace, and immediately remove it after stirring.

[0065] Step 2, the second furnace washing

[0066] Put the aluminum ash with a capacity of 0.5‰ of the furnace group into the hearth of the dry cleaning furnace for the second furnace cleaning, stir and spread the aluminum ash with a stirring rake, keep the temperature at 800°C, and keep the temperature for 2 hours; Stir evenly around to make the slag absorb the aluminum liquid precipitate...

Abstract

The invention dsiclsoes a cleaning method of an aluminum alloy dry cleaning furnace, and belongs to the field of alloy smelting. According to the cleaning method, the problems that in the aluminum alloy smelting process, when the products with high impurity volume change into the product with low impurity volume, the cost is high, and the working efficiency is low are solved. The method comprisesthe following steps that aluminum ash with 0.1-0.15% of a furnace set volume is put into a hearth of a dry cleaning furnace, the temperature is kept within the range of 850-900 DEG C, and the time is2 hours; the periphery of the hearth is uniformly stirred, aluminum ash adsorbs liquid aluminum separated out of the hearth, and the aluminum ash is pulled out after stirring; the aluminum ash with 0.05-0.1% of the furnace set volume is put into the hearth of the dry cleaning furnace, uniform stirring and paving are carried out, the temperature is kept within the range of 800-850 DEG C, and the time is 2 hours; and uniform stirring is carried out on the periphery in the hearth, so that the aluminum ash absorbs the liquid aluminum separated out of the hearth, and the aluminum ash is pulled outafter stirring. The cleaning method of the aluminum alloy dry cleaning furnace is high in working efficiency and low in production cost.

Description

technical field [0001] The invention belongs to the technical field of alloy smelting, and in particular relates to a cleaning method for an aluminum alloy dry cleaning furnace. Background technique [0002] At present, in the aluminum alloy smelting industry, as the price of non-ferrous metals continues to rise and the market is flooded with waste aluminum materials, recycled aluminum alloys are mostly used as casting production materials in the civil aluminum alloy industry, such as the auto parts industry and building materials industry. Due to the variety of aluminum materials recycled and purchased, the types and contents of metal elements contained in them are also uneven. Therefore, in the aluminum alloy smelting industry, when products with high content of impurity elements such as recycled aluminum are converted into pure aluminum products with low content of impurity elements , the cost rises and the work efficiency decreases. [0003] At present, there is no effe...
