Description
technical field [0001] The invention relates to the technical field of blowers, in particular to a method for transforming an axial flow blower. Background technique [0002] Axial-flow blast furnace blower is an important air supply equipment for ironmaking blast furnace. Due to many factors such as complex structure, high degree of automation, many public and auxiliary supporting equipment, and high manufacturing level requirements, the investment cost of designing and manufacturing a new blast furnace fan is high. It has become an important way for many iron and steel enterprises to reduce investment in equipment assets by using new technologies to expand and transform old fans to meet the air supply requirements of new blast furnaces. [0003] In recent years, iron and steel production capacity has been severely overcapacitated. Resolving overcapacity, eliminating backward enterprises, and pursuing comprehensive utilization and circular development have become the only w...
