在已建立的理论数学模型的基础上,以1Cr18Ni9Ti不锈钢为研究对象,模拟预测了薄带钢连铸过程的主要工艺参数(浇注温度、浇注速度及熔池高度)对双辊薄带钢凝固组织中柱状晶区比例、柱状枝晶间距和取向度的影响规律,从而为通过工艺优化来控制双辊薄带钢的凝固组织和实现对双辊薄带钢质量的最佳控制提供了理论依据。 Based on the established mathematical model, 1Cr18Ni9Ti stainless steel was taken as the research object to simulate and predict the main process parameters (pouring temperature, pouring speed and pool height) of the continuous casting process of thin strip, The proportion of columnar grains, the distance between columnar dendrites and the degree of orientation, which provides a theoretical basis for controlling the solidified structure of the twin-roll thin strip and optimizing the control of the quality of the double-strip thin strip through the process optimization.
