Improvement

in the ONLINE and OFFLINE analysis.

Currently the equipment is being used in Indian Rlys.

03.

2018-19

Safety

Development of Portable Digital Ultrasonic Flaw Detector with A-Scan Storage as per revised specification.

Developed advanced equipment with facilities such as enhanced storage capacity (about 100 Calibrations and 10,000 A-Scan), real time saving and easy logging, saving and transferring the test data to USB device as per revised specification No. RDSO/M&C/NDT/ 125/2004, Rev-II, January-2017

Improvement in features to make it more user friendly,

more storage capacity and OFFLINE

analysis

Currently the equipment is being used in Indian Rlys.

04.

2019-20

Safety

To Develop Digital Ultrasonic Single Rail Tester with colored signals as per revised specification.

Development of  advanced equipment with facilities such as  continuous recording of B-Scan at least 50Km , GPS location,

Facility to Recreation of A-Scan from saved B-Scan etc as per revised. RDSO/ M&C/NDT/128/2007 (B-Scan) Rev-III, July 2017 

 

Improvement in the reliability, continuous recording & storing the test data for traceability and Improvement in the OFFLINE analysis.

Currently vendors have been approved for manufacturing and supply to Indian Railways.

05.

2015-16

Safety

Standardization of LHB wheel specification in IRS R-19(Part-II)

Standardization of solid forged wheel for LHB coaches to reduce the problem of wheel shelling by modification of chemistry (increase of %age of alloy element and increasing web strength to the specification in IRS R-19(Part-II).

Modified wheel properties are targeted to achieve high speed run for more than 150KMPH

Presently it is used in LHB coaches.

06.

2017-18

Quality

Incorporation of EMS, AMLC and auto slag detector in continuous casting of rail blooms manufacturing process.

The internal quality (Homogeneity of inclusion) as well as surface finish is increased with rail blooms casting having facility EMS, AMLC and auto slag detector.  Process. These facilities promote for slag free pouring of steel, clean steel & chemical composition homogenization in the bloom, refinement of the solidification structure and the reduction in the content of inclusions.

Quality of rail steel increases

It has been installed by Rail manufacturer

07.

2018-19

Safety

Manufacturing of high strength 1080Cr grade Rails.

The high strength rail is demanding for higher axle load configuration in the track which combat the rail failure. The grade has been developed in SAIL/BSP.

The rail is higher strength than present 880Cr grade rail.

Weldability of 1080Cr grade rail is to be checked by manufacturer.

08.

2018-19

Safety

Standardization of high strength 350HT grade Rails

Standardization of   high strength 350HT grade Rails to facilitates high speed traffic and higher loading.

The rail properties are targeted to achieve higher speed and 25T loading

Indigenous manufacturer has to produce these rails.

09.

2018-2019

Safety

Development of LHB Wheels at Durgapur Steel Plant for Indian Railways as “Make in India” scheme of Central Govt.

  LHB Wheels as per requirements of IRS: R-19/1993 Part-II, Rev. 4, Corr. 1 of August 2015 has been developed at SAIL, DSP in consultation with M&C Directorate.

 

Steel compositions that has ensuring compliance of mech. Properties as per Corrigendum No. 1 of August 2015 has developed.

1. LHB wheels shall be suitable for a carrying wheelset of 18T Axle load provided with disk brakes for max. speed of 200 kmph + 10%.

 

2. In future, it will be provide import substitute to Indian Railways, thereby saving huge amount of foreign currency and generating employment in India.

3. LHB wheels are designed for coaches of premium trains like: Rajdhani, Shatabdi, Vandebharat express etc. to providing high speed journey solution with comfort and safety to the passengers.

1. Inspection of 1st batch of LHB Wheels (After machining) at Durgapur Steel Plant is completed and furthermore machining of 04 batches of LHB wheels is under process.

 

2. As a chain link, second plant for manufacturing LHB Wheel has been set up by Indian Railways at MCF, Raebareli in collaboration with RINL, Vishakhapattanam. Commissioning of Plant & Machinery got almost completed and production is likely to be started very soon.
