鉴于双辊薄带连铸等轴晶区半固态铸轧组织对产品性能的重要性,应用Calcosoft软件中的FE-CA方法对薄带柱状晶组织进行模拟,模拟结果与实验结果基本吻合,实现了柱状晶区的可视化.应用建立的微观组织模型,研究了三种工艺参数对柱状晶区宽度的影响.结果表明:随着熔池液面高度的增加,薄带柱状晶区宽度增加;随着浇铸温度和铸辊转速的增加,薄带柱状晶区宽度减小.
In view of the importance of the semi-solid cast-rolled microstructure of the equiaxed zone, such as twin-roll strip casting, to the product performance, the strip columnar grain structure was simulated by FE-CA method in Calcosoft software. The simulation results are in good agreement with the experimental results The effect of three process parameters on the width of the columnar grains was studied.The results show that the width of the columnar grains increases with the increase of the bath height, With the increase of casting temperature and casting roll speed, the width of columnar zone decreases.
