Maximum performance and significant cost savings at the 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 two 5500 m3 blast furnaces a blower station is necessarily set up.

• 11 synchronous motors (including three 60MW High Voltage motors, the largest ever installed in China, to drive the giant blowers)
• 6 sets of LCI’s (Load Commutated Inverters), including 2 sets of 14.5 MW SINAMICS GL150 starting converters) for the blast furnaces, air separation units and sinter plants
• Matching Transformers
• 1 set of Medium Voltage Switchgears
