Simulation Study on the Solidification Process of 6061 Aluminium Alloy by Twin-roll Casting
Based on NF6-300 vertical twin-roll thin strip continuous casting machine,the three-dimensional model of the casting and rolling zone of the two-roll casting and rolling process was established by using finite element software.The results show that with the increase of casting temperature and casting rolling speed,the overall temperature in the casting and rolling zone increases,the trans-verse temperature segregation degree decreases,the solidification end point moves to the exit,and the height distribution becomes more uniform.The optimum parameter combination of casting and rolling process of 6061 aluminium alloy is as follows:casting tem-perature is 690～710℃,casting and rolling speed is 13～15 m/min.
