Abstract

The invention discloses a casting method of a foam aluminum alloy platform. The casting method comprises the following steps: (1) recovered aluminum alloys are fed in a smelting furnace for smelting,and are heated to 700-730 DEG C to form melts; (2) aluminum powder of 100-200 meshes is fed as tackifier; and foaming agents are fed in the melts by adopting a melt foaming method; (3) the prepared melts are cast in a mold cavity through a casting mold gate; the mold preheating temperature is controlled within 140-200 DEG C before casting; the casting temperature is 700-730 DEG C; the casting speed is 1 kg / s; the melts are cooled by water after uniform casting in a mold; and the foam aluminum alloy platform is obtained after removal of the mold. Waste recoverable aluminum alloys generated in the industry and the life are adopted as raw materials for melt casting to form the foam aluminum alloy platforms; and the foam aluminum alloy platforms can be assembled for lengthening, are enough inpressure resistance and deformation resistance, and are high in corrosion resistance.

Description

technical field [0001] The invention belongs to the technical field of recycled aluminum alloy reuse, and in particular relates to a casting method of a foamed aluminum alloy platform. Background technique [0002] With the development of education, the improvement of teaching equipment is imminent. The original traditional wooden or composite board platform has the disadvantages of easy corrosion and high noise, which affects the effect of learning and lectures, and the cost is high, and it is a whole. The platform is not easy to move and move. However, the recycling of aluminum alloy materials produced by the extensive use of aluminum alloy materials in the fields of construction, civil, industry, transportation, military and aerospace will cause waste and pollution. Therefore, it is necessary to find out for the reuse of recycled aluminum alloys. A new way of exploiting. And so far, there has been no relevant report on the use of recycled aluminum alloys to prepare foam...
