3进口铁矿烧结经济分析对进口铁矿作经济分析时，应以最终炼1t铁需要花多少钱来衡量。这里既作烧结原料成本分析，又计算出炼1t生铁所需要的烧结矿量和炼1t铁所需要的烧结矿原料成本。在烧结生产中，常常引入“单烧值”的概念，即单独以某一种矿石进行烧结时，在一定的碱度下， 3 imported iron ore sintering economic analysis of imported iron ore for economic analysis, the final refining 1t iron should be how much money to measure. Here are both raw material cost analysis of sintering, but also calculate the required amount of sinter 1t pig iron refining and refining 1t iron required sintering cost of raw materials. In the sintering production, often introduced the concept of “single firing value”, that is, when sintering with a certain kind of ore alone, at a certain alkalinity,
