Lean Design and Improvement of Supporting Blower for Angang 2 # Blast Furnace
Due to the adjustment of the production mode of the blast furnace,the blower often operates under the condition of small air volume and high air pressure,and the operating point is close to the surge vent regulating line,so the anti surge valve is often opened,the unit is in the vent operation state,the blower output cannot be fully utilized,and the operating cost is high.In addition,when the blast furnace blower is started,the air supply check valve cannot be opened normally due to the limitations of process technology and other conditions,affecting the normal air supply of the blast furnace.This article describes the innovation and transformation methods carried out according to the actual situation on site.After the implementation of the methods,the problems can be solved,and some solutions can be given to the same industry when encountering the same problems.
