Embodiment Construction
[0016] A kind of production technology of aluminum alloy sheet material for automobile, it is characterized in that comprising the following steps:
[0017] (1) Meet the following requirements according to the mass percentage of elements: Mg0.8-1.2, Si0.6-1.1, Cu0.3-0.5, Fe0.2-0.3, Mn0.5-0.8, Zn0.1-0.2, Ti0.05 -0.15, Bi0.4-0.7, Sb0.3-0.5, Ga0.1-0.2, Y0.04-0.06, Ce0.03-0.05, Pm0.02-0.03, the balance is Al for batching, and the charge is put into smelting The furnace is smelted at 740°C. After the metal is completely melted and stirred evenly, a sample is taken from the middle of the depth of the molten aluminum and on both sides of the furnace for analysis. After the analysis is qualified, it can be converted into a furnace;
[0018] (2) After the melt is transferred to the static furnace, using nitrogen as a carrier, spray refining agent powder into 2 / 3 of the depth of the molten aluminum for refining. The nitrogen pressure is 1.3kg / mm, the refining temperature is 720°C, and t...

Abstract
The invention discloses a production technology of an automobile aluminum alloy sheet. The above aluminum alloy comprises, by mass, 0.8-1.2% of Mg, 0.6-1.1% of Si, 0.3-0.5% of Cu, 0.2-0.3% of Fe, 0.5-0.8% of Mn, 0.1-0.2% of Zn, 0.05-0.15% of Ti, 0.4-0.7% of Bi, 0.3-0.5% of Sb, 0.1-0.2% of Ga, 0.04-0.06% of Y, 0.03-0.05% of Ce, 0.02-0.03% of Pm, and the balance Al. Small amounts of a plurality of alloy elements comprising Y, Ce, Pm, Ga, Bi and the like are added to refine crystal grains and change the recrystallization state, so the high temperature strength, the fatigue resistance, the wear resistance, the impact resistance and the like of the alloy are improved, casting, rolling and heat treatment technologies are improved, and good comprehensive performances are obtained. The aluminum alloy sheet produced in the invention has excellent strength, wear resistance, impact resistance, fatigue resistance, high temperature resistance and the like, and can be widely used in all components of the body, wheels, fuel tank, cylinder body and the like of an automobile.
Description
technical field [0001] The invention relates to a production process of aluminum alloy plates and strips for automobiles, belonging to the technical field of aluminum alloy materials. Background technique [0002] In recent years, the use of aluminum alloy in vehicles has been widely valued, replacing other materials (such as steel, plastic, etc.) and other structures. Although aluminum alloy has the advantages of good formability, good thermal conductivity, good plasticity, and high strength, its fatigue resistance, impact resistance, wear resistance, and high temperature resistance still need to be improved. Contents of the invention [0003] In order to solve the above problems, the present invention provides a production process of aluminum alloy plate and strip for automobiles with high high temperature strength, good shape, high impact resistance, high wear resistance and high fatigue resistance, so as to prolong the service life of aluminum alloy materials. [000...
