摘　　要：以等价比热容法为研究基础,提出了双辊薄带铸轧凝固过程中的宏观数学模型和微观数学模型,以固相率为媒介实现了宏微观数学模型的耦合求解。通过Al-4.5Cu金属液的实际双辊薄带铸轧凝固试验,验证了微观数学模型的有效性和可靠性,为铸轧工艺的优化提供可行性参考。Based on the equivalent specific heat method, the macro and microscopic mathematical model for twin roll thin strip in casting solidification process were put forward, the mathematical model was solved by coupling taking solid phase fraction as media. Through the casting solidification test of actual twin-roll strip of AI-4.5Cu liquid metal, the validity and reliability of the mathematical model were verified, which can provide a feasible reference for optimizing casting process.
