一、序言改善矿石原料的质量,大家知道,这是高炉增产和高炉焦比降低的最重要方法之一。高炉生产的理论和实践,对矿石原料的质量提出了下列总的要求:1)含铁量应尽量地高,有害杂质的含量应尽量地低;2)还原性高;3)透气性高;4)碱度高;5)堆比重大。高炉的矿石原料要能满足上述总的要求,必须具 First, the preamble to improve the quality of ore raw materials, we all know, this is one of the most important ways to increase blast furnace and reduce the coke ratio. The theory and practice of blast furnace production put forward the following general requirements for the quality of ore raw materials: 1) the iron content should be as high as possible, the content of harmful impurities should be as low as possible; 2) the high reducibility; 3) 4) Alkalinity is high; 5) Heap proportion is big. Blast furnace ore raw materials to meet the above general requirements, must have
