Abstract：After heavy repair of No 4 blast furnace, the pulverized coal system can not satisfy the capacity of pulverized coal injection. Revamping of the pulverized coal system was performed as the heavy repair of No 5 blast furnace. The pulverized coal preparation system adopted the process circuit of single pipeline of parallel hoppers, densephase transport technology and straight injection, which can satisfy the injection process of No 4 blast furnace.
