Embodiment

[0026] Such as figure 1 A preparation process for a high formability 6111 aluminum alloy automobile sheet is shown, comprising the following steps:

[0027] A. Ingredients: The aluminum alloy raw materials for the preparation of aluminum alloy plates are mixed according to weight percentage, namely: Si: 0.5-1.0%, Fe: 0.1-0.4%, Cu: 0.6-0.8%, Mn: 0.2-0.4%, Mg : 0.6~0.8%, Cr: 0.10%, Zn: 0.10%, single impurity ≤0.05%, total ≤0.15%, the balance is Al;

[0028] B. Melting and casting: Put the configured aluminum alloy raw materials into the melting furnace in turn for melting. The aluminum alloy raw materials are industrial pure aluminum, industrial pure Mg, industrial pure Zn, master alloy Al-Si, master alloy Al-Cu, master alloy Al -Fe, intermediate alloy Al-Mn, etc., and use flux to refine and cover. After feeding, start stirring when aluminum water appears in the furnace. After stirring evenly, it will be melted into liquid aluminum alloy. The melting temperature is 700-760 ° C....

Abstract

The invention belongs to the technical field of metal materials, and relates to a preparation process of a high-formability 6111 aluminum alloy automobile sheet. The process comprises the following steps: casting, three-stage homogenization, hot rolling, annealing, cold rolling, annealing, cold rolling, solid solution quenching and pre-aging. An intermediate annealing process in the cold rolling process is carried out on a continuous annealing line, and the annealing schedule is 480 DEG C/20 s. Through mutual cooperation of hot rolling, medium annealing and cold rolling processes, An r value excellent in three directions is obtained, the solid solution quenching and pre-aging processes are combined with an existing continuous annealing production line, the process is more suitable for actual industrial production, and finally the high-formability 6111 aluminum alloy automobile plate material capable of being applied to industrial production is obtained.

Description

technical field [0001] The invention belongs to the technical field of metal materials and relates to a preparation process of a highly formable 6111 aluminum alloy automobile plate. Background technique [0002] Under the urgent situation that the world's industrial development requires energy saving and environmental protection, some developed countries have formulated automobile fuel economy regulations and increasingly strict exhaust emission regulations. Therefore, reducing the weight of automobiles to reduce energy consumption, reduce pollution, and improve efficiency has become an important measure for major automobile companies to improve their competitiveness. Aluminum alloy and its processing materials are widely used in the automotive industry due to a series of excellent characteristics such as low density, high specific strength and specific stiffness, good elasticity, good impact resistance, corrosion resistance and good processing performance. important mater...
