| Abstract: | Through paying more attention to the quality of raw material and fuel, optimizing burden structure, implementing the mixed injection of bituminous coal and anthracite, improving blast furnace operation system, stabling furnace temperature, improving the coal gun and strengthening iron tapping and other measures, Laiwu Steel＇ s 3 200 m3 BF achieved the low-energy consumption smelting. The pulverized coal injection rate reached to 170 kg/t, the large coke ratio reduced to 300 kg/t and the average fuel ratio reduced to 515 kg/t. |
