| 摘 要： | 为降低配煤成本,增加气煤、气肥煤等省内煤炭资源的利用量,提高煤气发生量,缓解焦炉煤气供应不足,济钢在小焦炉试验、工业试验的基础上,调整了6 m焦炉配煤方案,增配了10%的省内气煤、气肥煤,吨煤成本降低7.5元,年降配煤成本1095万元。焦炭质量水平变化整体上对高炉影响不明显,能满足高炉要求。

| Abstract: | In order to decrease coal blending cost,add gas and fat-gas coal of Shandong Province utilization and increase coke gas throughput,on the base of 20 kg test oven experiment and pilot test,we added 10 percent gas and fat-gas coal of Shandong Province in 6 m coke oven coal blending.Then cost of coal blending per tone was decreased by 7.5 yuan and the cost was decreased by 1.095 million yuan in a year.At the same time,the change of the coke quality indexes had no obvious influence on the blast furnace and could meet the needs of BF. |
