Embodiment 1

[0023] A preparation method of a high-density, lightweight engineering vehicle frame material, the specific method is as follows:

[0024] (1) Take the aluminum alloy raw material, melt it at 740°C, and mix the components evenly. Take the sample for testing, and perform feeding according to the test results, and the feeding temperature is 740 °C. Then carry out refining, refining temperature is 740 ℃, refining agent dosage is 0.8kg / t-Al, time is 10 minutes, and the refining agent contains MgCl 2 , KCl and MgO. Double-tube refining is adopted, and the height of the bubbles is below 80mm, so that the components are further mixed evenly. Then, the refined product is slag-removed once, the scum on the surface of the melt is cleaned up, and the sample is taken again for analysis. After passing the qualification, the converter temperature is controlled at 740 ° C, and the slag removal time is 10 minutes, so that the surface of the material is smooth and free of dirt. After the gu...

Abstract

The invention relates to a method for preparing a frame material for high-density and lightweight engineering vehicles, and belongs to the technical field of aluminum alloy manufacturing. The method comprises the following steps: (1) smelting and casting the aluminum alloy to obtain an aluminum alloy ingot; (2) homogenizing the aluminum alloy ingot and performing composition detection; (3) extruding the aluminum alloy ingot; (4) extruding the aluminum alloy ingot; The final aluminum alloy ingot is quenched, stretched and straightened, cut to length, and double-stage artificial aging. Samples are taken for inspection to obtain frame materials for engineering vehicles. By controlling the manufacturing process of the aluminum alloy and the content of various chemical components in the aluminum alloy, the present invention makes the alloy composition more stable, the performance is higher than that before the transformation, and the tensile strength, yield strength, elongation, Brinell hardness, etc. Aspects are higher than the national standard. By improving the performance of the aluminum alloy, the amount of aluminum alloy used in the construction vehicle can be effectively reduced, so as to achieve the purpose of reducing the weight of the construction vehicle itself.
