摘　　要：基于数值模拟，采用正交实验的方法研究了Cu／Al／Cf充芯连铸工艺。结果表明，二冷水距结晶器距离11、连铸速度v、芯管长度12作为主要参数，对连铸质量影响最大，且存在明显的单调关系；一冷水流量，和铝液温度腓为次要因素。最佳工艺参数分别为：一冷水流量产280L／h，二冷水距结晶器距离11=50～60mm，连铸速度v=80～100mm／min，芯管长度12=75～80mm。Based on the numerical simulation, Cu/Al/Cf continuous core-filling casting process was investigated through orthogonal test. The results show that the distance between secondary cooling water and crystallizer l1, drawing speed v and core tube length l2, as major factors, have the greatest impact on the quality of continuous casting slab. Meanwhile, there exist some monotonous relations between these parameters and the influences. Flow of primary cooling water f and liquid aluminum temperature T are the minor concern. The optimized parameters of continuous core-filling casting process are f=280 L/h, l1=50-60 ram, v=80- 100 turn/rain, l2=75-80 mm.
