The 415V, three-phase AC motors range from 15 to 315kW and are being used on Weir Pumps in slag slurry, slag granulation, cooling circuit water and recirculation duties via vee belt drive trains.

Weir Minerals has chosen WEG EFF1 B3 induction motors for 20 pumps commissioned for a Paul Wurth blast furnace being installed at the Vizag Steel Works in Andhara Pradesh, India.

Operational from 2009, the new 3800m3 furnace on the Vizag site will be one of the biggest, most efficient and up to date blast furnaces in India.

The 415V, three-phase AC motors range from 15 to 315kW and are being used on Weir Pumps in slag slurry, slag granulation, cooling circuit water and recirculation duties via vee belt drive trains.

The six high-volume, heavy-duty slurry pump sets are driven via a VVF (variable voltage frequency) drive to match the duty cycles, while the slag granulation water, recirculation and cooling water pump motors employ direct online starting.

"WEG motors have an excellent track record in the metal and mining industries", Russell McCabe, Field Sales Manager at WEG Motors (UK) said.

"Additionally, we have good support services in India and, in fact, are in the process of building our own production facilities".

"This means that world-class Indian industries such as steel making will benefit from a direct presence".

Handling of blast furnace slag is an important aspect of modern blast furnace operation.

Today, blast furnace slag is a saleable product (granulated slag for concrete making) rather than a waste material.
