Abstract

The invention discloses a method capable of using recycled aluminum for pressure casting of an aluminum alloy. The method comprises following steps that firstly, the recycled aluminum alloy is sortedaccording to the impurity content from low to high, the recycled aluminum with the low impurity content is fed, and the recycled aluminum and an electrolysis aluminum ingot are heated and melted; secondly, alloy liquid in the first step is subjected to electromagnetic stirring, and a silicon ingot is added into the alloy liquid in the first step to form alloy liquid; thirdly, the recycled aluminumingot with the higher impurity content is added into the alloy liquid in the second step; fourthly, Cu, Sn and B are added in the alloy liquid in the second step or the alloy liquid in the third stepto make an aluminum melt; fifthly, a deslagging agent is added into the aluminum melt, and stirring and deslagging are carried out; sixthly, the aluminum melt obtained after deslagging is continuously heated and standing is carried out; seventhly, the aluminum melt obtained after deslagging is transferred to a heat preservation furnace to be subjected to heat preservation, the made aluminum meltis subjected to pressure casting, and the radiator is made; the invention further discloses a composition of the aluminum alloy used by the radiator. The recycled aluminum resources are reasonably applied, and in combination with the smelting and pressure casting technology, the radiator which is high in strength and good in heat conduction is obtained.

Description

technical field [0001] The invention relates to the field of alloys, in particular to a method for preparing a radiator by using recycled aluminum and the aluminum alloy used in the radiator. Background technique [0002] High thermal conductivity Al-Si cast aluminum alloy is of great significance in energy saving and environmental protection. With the improvement of life in our country, there are more and more cast aluminum alloy household heating systems. Although compared with steel materials, the thermal conductivity of aluminum alloy has been greatly improved, but people have not fully understood the potential of aluminum alloy thermal conductivity, and the work of tapping the potential is not deep enough. Because the main energy consumption of a family is concentrated in heating. As our country enters a well-off level in an all-round way, people have a higher pursuit of life. Heating equipment has expanded from the north of the Yellow River to the south of the Yangt...
