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.
