Durgapur Steel Plant (DSP) unit of Steel Authority of India limited (SAIl) dispatched the first consignment of Metro Rail wheels for Kolkata Metro on 29 June. The consignment was flagged off by AK Rath, CEO, DSP.
“DSP is the only forged wheel producer in the country. We proudly say that the nation moves on DSP wheels. Now Kolkata Metro Railway will also run on DSP wheels,” said Rath on the occasion.
In the first consignment, 46 wheels have been despatched and in the first lot, 73 numbers of OK wheels have been made ready.
The development of wheels for use by Kolkata Metro was successfully done with the complete use of in-house resources. The design of Kolkata Metro wheel is critical due to its complex web profile, which is different from the existing products that are supplied by DSP. The dimensions of these wheels are also different from the existing wheels. This called for new designing of forging dies, rolls and subsequent manufacturing, heat treatment and machining. It was followed by inspection in presence of RDSO for final dispatch.
In the true spirit of ‘Make in India’, DSP envisages to continue developing new products to suit the country’s needs.
