Embodiment Construction

[0023] The present invention will be further described below in conjunction with embodiment, but not limited to following embodiment.

[0024] A method for smelting and preparing aluminum alloy profiles with chromization treatment, comprising the following steps:

[0025] (1) Configuration of aluminum alloy melt:

[0026] According to the following parts by weight (kg) of raw materials: 55 parts of 5052 aluminum ingots, 32 parts of discarded aluminum products, 5 parts of boron carbide, and 5 parts of nano-ceramic powder, the fineness of boron carbide is 5-8 μm, and the above raw materials are added In the smelting furnace, when the temperature rises until the charge starts to soften and slump, sprinkle a layer of covering agent on the surface of the melt; when the charge is completely melted, the melt should be properly stirred to make the temperature in the molten pool uniform, Add magnesium ingots in the body; control the mass percentage of each element in the melt as follo...

Abstract

The invention discloses a smelting preparation method of a chromized aluminum alloy profile. The smelting preparation method comprises the following operational steps: (1) configuring an aluminum alloy melt: mixing the following raw materials in parts by weight: 55-60 parts of 6063 aluminum ingot, 30-40 parts of waste aluminum product, 5-10 parts of chromium carbide and 5-7 parts of glass slag powder, adding the raw materials into a smelting furnace, heating till a furnace charge is softened and collapses, and scattering a layer of covering agent on the surface of a molten solution for covering; and properly stirring the melt after the furnace charge is completely molten so as to enable the temperature in a melting bath to be uniform and consistent and finally adding a magnesium ingot into the melt. The waste aluminum material is added into the raw materials for mixing so as to be conductive to stabilizing the performances of the aluminum profile and reducing the possibility of affecting the quality of the aluminum profile due to the appearance of the non-detected materials during the smelting of the aluminum liquid; and the surface of the aluminum alloy profile is chromized, so that the anti-corrosion capability of an oxide film on the surface of the aluminum alloy profile and the bonding force between the aluminum alloy profile and a coating are improved.

Description

technical field [0001] The invention relates to a method for smelting and preparing aluminum alloy profiles with chromization treatment, and belongs to the technical field of aluminum alloy material processing. Background technique [0002] Aluminum alloy is the most widely used non-ferrous metal structural material in the industry, and has been widely used in aviation, aerospace, automobiles, machinery manufacturing, and ships. With the rapid development of science and technology and industrial economy in recent years, the demand for welded structural parts of aluminum alloys is increasing, and the research on the weldability of aluminum alloys is also in-depth. The wide application of aluminum alloy has promoted the development of aluminum alloy welding technology, and the development of welding technology has expanded the application field of aluminum alloy, so the welding technology of aluminum alloy is becoming one of the hot spots of research. The aluminum-plastic pan...
