摘　　要：通过进行高炉空气动力学模型试验,用二次旋转组合设计的方法建立了描述相对于层装,混装改善块状带透气性的数学模型。讨论了模型的预报及各因素之间的等高线图,为混装工艺的实际应用提供了理论依据。A mathematical model is developed through aerodynamic modelling on a blast furnace in laboratory using the method of secondary rotary combination design.The model describes the permeability improvement over layered charge when using mixed charge. Predictions and contour diagrams among various factors obtained from the model are discussed so as to provide theoretically the application of mixed charge process.
