摘　　要：运用正交试验法设计了回转窑焙烧低品位菱铁矿的实验方案。试验结果说明,焙烧温度是影响菱铁矿焙烧矿质量的第一因素,风煤比和给矿量对焙烧指标也有重要影响,而焙烧时间对焙烧影响不显著。A research on roasting of poor siderite with orthogonal experimental method was carried out. It is shown that roasting temperature is the most important factor. The proportion of air and coal also has important effect on magnetization roasting. However, roasting time has little effect on magnetization roasting.
