| Abstract Scope |
Based on the needs of improving efficiency and saving cost, the production of 8021 aluminum alloy for aluminum-plastic film by short-flow casting and rolling process instead of the traditional long-flow hot rolling process has become one of the hot spots in the research of aluminum foil design and development. In this paper, we take the industrial experimental production of 8021 cast-rolled sheets as the research object, combined with thermodynamic calculations and microscopic characterization techniques to study the influence law of Al-Ti-B wire addition and cast rolling thickness on the organization, second phase and mechanical properties of cast rolled sheets. The results show that Al3Fe is converted to Al(Fe, Mn)Si, α-AlFeSi and β-AlFeSi during the temperature reduction process, and that under the condition of keeping the aluminum flux unchanged, the addition of Al-Ti-B wire and the thickness of cast-rolled sheets significantly affect the microstructural characteristics of cast-rolled sheets. Increasing the Ti content and cast-rolled thickness will improve the microstructure and compositional homogeneity of the cast-rolled sheets, and the mechanical properties can be improved. |
