Abstract Scope |
Due to the lightweight production technology of automobiles, aluminum alloys have advantages over steel, and a better understanding of the temperature distribution and freezing point position during the casting process is very important for producing high quality aluminum strips.In this paper, the enthalpy- porosity solidification model of ANSYS FLUENT software was used to establish a two-dimensional mathematical model of the two-roll casting and rolling zone of 6061 aluminum alloy, and the flow, heat transfer and solidification in the molten pool were simulated.Different casting parameters (casting speed, cooling strength and pouring temperature) were simulated and calculated. Analyze the influence of different process conditions on the degree of temperature field distribution and the location of freezing point, and determine the reasonable range of process parameters under high-speed casting conditions. Numerical calculations using existing models provide guidance for 6061 aluminum alloy twin roll casting. |
