Progress and development trend of aluminum alloy twin-roll casting process
As one of the advanced preparation methods for aluminum alloy sheet and strips,the twin-roll casting(TRC)process is in line with the current dual carbon strategy requirements of"carbon peak and carbon neutrality",and plays a significant role in promo-ting the development of China's high-end lightweight aluminum alloy industry towards green and intelligent directions.The paper summarized the development history and current situa-tion of aluminum alloy TRC process through systematic research and analysis.It focused on the formation mechanism of segregation defects in high-alloying aluminum alloy cast-rolled sheets,systematically elaborated the experimental research of electromagnetic field and nu-merical simulation in the aluminum alloy TRC process,and analyzed the development trend of TRC technology.The paper provides reference and guidance for the development of high-end lightweight aluminum alloy TRC technology in China.
