Embodiment Construction

[0029] The present invention will be further described below in conjunction with examples, but it is not limited to the following examples.

[0030] A smelting preparation method for electrostatic powder sprayed aluminum alloy profiles includes the following operation steps:

[0031] (1) Making aluminum alloy melt:

[0032] According to the following parts by weight (kg) of raw materials: 55 parts of 3003 aluminum ingots, 32 parts of discarded aluminum products, 5 parts of boron carbide, and 5 parts of nano quartz sand powder. The fineness of boron carbide is 5-8μm. Join the smelting furnace, and when the temperature is raised until the charge starts to soften and collapse, sprinkle a layer of covering agent on the surface of the melt. The covering agent is composed of the following parts by weight (kg): 10 parts CaO, 10 parts AL 2 O 3 , 45 parts SiO 2 , 12 parts of charcoal, 23 parts of fly ash;

[0033] 2) Refining treatment:

[0034] Use refining agent to refining the aluminum alloy...

Abstract

The invention discloses a smelting preparation method for an electrostatic powder-plated 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 for facilitating the stable 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 chromizing treatment is carried out on the surface of the aluminum alloy section bar, so that the corrosion resistance of the oxide film on the surface of the aluminum alloy section bar and the binding force of the aluminum alloy section bar and the coating are improved.

Description
