摘要:

针对原料煤灰分高、黏结指数低的特点,通过优化原料结构及200 kg焦炉试验,优选出最佳的配煤结构,并进行了生产实践。结果表明,在优质煤降低5%~15%的条件下,FC80焦与FC83焦强度指标持平,能满足1 000 m3以下高炉用焦质量要求。

Abstract:

In View of the characteristics of high ash content and low caking index of raw coal,an optimum coal blends was selected by optimizing the raw material composition and through 200 kg pilot oven test,and the production was put into practice.The results showed that under the condition of reducing the premium coal by 5%~15%,the strength index of FC80 coke and FC83 coke are equal,which can meet the requirements of coke quality for blast furnace smaller than 1,000 m3.
