Outstanding performance and cost savings at Blast Furnace Blowers

The Shougang Jingtang United Iron & Steel Co., Ltd. with an annual steel output of about 10 million tons of iron and steel is located in the Caofeidian Industrial Zone of Tangshan City, Hebei Province.
For the two 5500 m3 blast furnaces a blower station is necessarily set up. Three axial-flow BF blowers (two in operation and one stands by) are installed inside the blower station. The maximum air volume of the blowers is 10000 Nm3/min and the air pressure at outlets is 0.65 MPa(a).
