| Abstract: | Aiming at the condition of actual raw material and fuel for No.2 1 000 m^3 blast furnace, Laiwu steel optimized the screening opera- tion and burden design. Through replacing the vibration screen and optimizing the working mode of the screen, the charged powder of raw material and fuel was decreased to 3 percent; through strengthening the screening for lump ore and up and down regulating system, the permeability was ameliorated; through reasonable use small coke, the utilization ratio of coke was increased. Then the blast furnace was stable and regular working. |
