SAIL – DSP despatched 1st consignment of Wheels for Kolkata Metro
Adding another feather to its cap in its endeavor to contribute and actively participate in ‘Make in India’, Steel Authority of India Ltd.’s (SAIL) Durgapur Steel Plant (DSP) despatched the first consignment of metro railway wheels for Kolkata Metro today. Earlier the wheels for Kolkata Metro Rail were being imported. This is an important step towards import substitution and in the true spirit of making in India SAIL envisages developing new products to suit the country’s need.
The development of Kolkata Metro wheel was successfully done with complete 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. These 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. SAIL DSP is poised to meet the entire demand of Kolkata Metro.
