Embodiment 1

[0053] Step 1, the smelting furnace is loaded with raw materials and melted;

[0054] Pour the raw materials into the molten aluminum and heat to melt. Stir twice during the melting process. Stir the bottom material in the furnace evenly. The stirring time is 4 minutes each time. Add slagging agent during the second stirring. The raw material is pure aluminum ingots. And electrolytic aluminum liquid, without adding other waste materials, aluminum ingots account for 30%;

[0055] Step 2. Adjust alloy content:

[0056] Sampling the melt obtained in step 1, adding different alloys after detecting the alloy composition, and adjusting the mass ratio of alloy content and composition: Fe0.3%, Mg 0.3%, Si 1.0%, Cu≤0.2%, Zn≤0.2% , Mn0.15%, Ti0.1%, Cr0.10%, and the balance is Al. After the charge is completely melted, when the temperature of the melting furnace rises to 710°C, slag removal and stirring are carried out for 8 minutes, and then the first sampling is carried out. When the...

[0063] Step 1, the smelting furnace is loaded with raw materials and melted;

[0064] The raw materials are poured into molten aluminum and then heated and melted. Stir three times during the process of melting the material. Stir the bottom material in the furnace evenly. The stirring time is 6 minutes each time. Add slagging agent during the second stirring. The raw material is pure aluminum ingot And electrolytic aluminum liquid, without adding other waste materials, aluminum ingots account for 45%;

[0065] Step 2. Adjust alloy content:

[0066] Sampling the melt obtained in step 1, adding different alloys after detecting the alloy composition, adjusting the mass ratio of the alloy content to: Fe0.5%, Mg0.8%, Si1.5%, Cu0.2%, Zn0. 2%, Mn0.2%, Ti0.15%, Cr0.10%, and the balance is Al. After the charge is completely melted, when the temperature of the smelting furnace rises to 720°C, carry out slag removal and stirring for 10 minutes, and then take the first sampling , when t...

Embodiment 3

[0073] Step 1, the smelting furnace is loaded with raw materials and melted;

[0074] The raw materials are poured into molten aluminum and then heated and melted. Stir 2-3 times during the process of melting the material. Stir the bottom material in the furnace evenly. The stirring time is 5 minutes each time. Add slagging agent during the second stirring. The raw material is pure Aluminum ingots and electrolytic aluminum liquid, without adding other waste materials, aluminum ingots account for 40%;

[0075] Step 2. Adjust alloy content:

[0076] Sampling the melt obtained in step 1, adding different alloys after detecting the alloy composition, adjusting the mass ratio of the alloy content to: Fe 0.2%, Mg0.35%, Si 1.2%, Mn0.1%, Ti0.08% , Cr0.05%, and the balance is Al. After the charge is completely melted, when the temperature of the smelting furnace rises to 710-720°C, carry out slag removal and stirring for 8-10min, then take the first sampling, and add compounding at th...

Abstract

The invention discloses a casting and rolling method of 6××× series aluminum alloy plates for automobiles, which includes smelting furnace-loaded raw materials, melting, adjusting alloy content, electromagnetic stirring, refining, slag removal, standing, turning the furnace, discharging, and on-line Crystal refinement, degassing, slag removal by filtration, and casting and rolling. After the strips are obtained, they are cut and coiled to become casting and rolling billets. The cast-rolled billet processed by the present invention has good mechanical properties, the strip hardness is 60-90HV, the tensile strength is 150-200MPa, the yield strength is 120-160MPa, the elongation after breaking is 20-30%, and the product is bent at 90° without cracks , to meet the next production requirements.

Description

technical field [0001] The invention relates to the technical field of aluminum alloy casting and rolling, in particular to a casting and rolling method of 6××× series aluminum alloy plates for automobiles. Background technique [0002] The production of cold-rolled strip by twin-roller casting-rolling machine has the advantages of short process, low investment, energy saving and environmental protection, etc., but the production efficiency of conventional aluminum strip casting and rolling process is low, the types of alloys that can be cast and rolled are limited, and the internal structure of cast-rolled slab And the mechanical properties are far lower than those produced by traditional hot-rolled slabs. For the production of high-alloy products with high deep-drawing properties, especially the production of automotive sheet blanks, and for the large improvement in casting and rolling production efficiency, it is still It is a difficult problem in the development of a new...
