Based on the property research and the benefit calculation about PCI of single type of coal and blended coal home and abroad, Shougang optimized model of coal blending calculation for pulverized coal injection (PCI) is established. The model companied the cost of coal blending, coal grinding and technical and economic indexes of blast furnace (BF) quite well based on meeting all properties indexes. And the good applicability of model has been proved by industrial experiments further.
