The Practice to Adjust the Material System of 1^#1880m^3 Blast Furnace

The contrast of some key indicators before and after adjusting material system after the blowingin of l^#1880m^3 of the ironmaking plant in Laiwu steel was carried out, especially the change of key parameters including the wind pressure of blast furnace, the level of permeability index and the temperature level at the top of blast furnace, and the furnace resistance to external fluctuations, before and after adjusting the material system were introduced in the paper, and through the comprehensive contrast of indexes ,the material system summarized and adjusted was is suitable for l^#1880m^3 blast furnace, and the paper mainly focused on the furnace running conditions of key time nodes after overhaul and blowing-in.
