Abstract

The invention discloses a smelting preparation method for an anti-cracking aluminum alloy section bar. The smelting preparation method comprises the following operation steps: (1) preparing aluminum alloy melt, wherein the aluminum alloy melt is prepared from the following materials in parts by weight: 55-65 parts of 3003 aluminum ingots, 32-42 parts of waste aluminum products, 5-10 parts of boron carbide and 5-10 parts of nanometer quartz sand powder; adding the materials to a smelting furnace; scattering a layer of covering agent to the surface of the melt to cover the melt when the furnace materials are heated up to be softened and collapsed, wherein the covering agent comprises the following components in parts by weight: 10-20 parts of CaO, 10-25 parts of Al2O3, 35-45 parts of SiO2, 12-30 parts of C and 12-23 parts of coal ashes. According to the smelting preparation method disclosed by the invention, the waste aluminum materials are added to the material ingredients, and the waste aluminum materials are smelted by one step and stable in components, and so the waste aluminum waste materials added to the ingredients are beneficial to stabilizing the performances of the aluminum section bar and reducing the possibility that the quality of the aluminum section bar is affected by undetected materials during the smelting process of the melt. The dosage proportion of the relevant ingredients in the aluminum section bar formula is adjusted, so that the formula is further optimized.
