Embodiment Construction

[0025] The present invention will be further described below in conjunction with embodiment, but not limited to following embodiment.

[0026] A method for smelting and preparing aluminum alloy profiles, comprising the following steps:

[0027] (1) Configuration of aluminum alloy melt:

[0028] According to the following parts by weight (kg) of raw materials: 55 parts of aluminum ingots, 30 parts of discarded aluminum products, 5 parts of chromium carbide, and 5 parts of glass slag powder, the fineness of chromium carbide is 5-8 μm, and the above raw materials are added to smelting Furnace, when the temperature rises until the charge begins 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, and finally to the melt Add magnesium ingot; control the mass percentage of each element in the melt as follows: 0.17%≤Si≤0.25%, 1....

Abstract

The invention discloses a smelting and preparation method of an aluminum alloy profile. The smelting and preparation method comprises the following steps of: preparing an aluminum alloy melt; preparing from the following raw materials in parts by weight: 55-60 parts of aluminum ingots, 30-40 parts of waste aluminum products, 5-10 parts of chromium carbide and 5-7 parts of glass dreg powder, wherein the fineness of the chromium carbide is 5-8 mu m; feeding the raw materials into a smelting furnace, heating till the furnace materials are softened and collapsed down, and scattering a layer of covering agent on the surface of the melt to cover; when the furnace materials are completely smelted, appropriately stirring the melt so as to make the temperatures at every part of the smelting pool uniform; and finally adding magnesium ingots into the melt. By carrying out chromizing treatment on the surface of the aluminum alloy profile, the corrosion resistance of an oxidation film on the surface of the aluminum alloy profile and the binding capability of the aluminum alloy profile with a coating are improved.

Description

technical field [0001] The invention relates to a method for smelting and preparing aluminum alloy profiles, 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 panel is a new type of material...
