Cast Manganese Crossings
Explosion Depth Hardening of CMS Crossings
VAEVKN are currently approved suppliers from RDSO for the following types of CMS Crossings
- 1:12, UIC 60
- 1:8.5, UIC 60
- 1:12, IRS 52
- 1:8.5, IRS 52
- 1:16, UIC 60
- 1:20, UIC 60
- 1:8.5, IRS 52 Obtuse
- 1:8.5, IRS 52 Meter Gauge
Currently a develepmental order of four more types of CMS Crossing for a complete Scissor Crossover is under execeution
CMS Crossings being used on the track of Indian Railways have the surface hardness of 180-220 BHN and under traffic load leads to metal flow on the top running surface, hence adversely affecting the service life and comforts. In order to seize this tendency of metal flow to crop up appreciated increase in life span and service comforts, the surface hardness of the top surface needs an increase to the range of 330 – 360 BHN, which can be achieved by imparting “Explosion Depth Hardening” (EDH) process.
Through application of the ‘EDH’-process, the total life of the CMS Crossing can reach up to double its conventional life, in addition to the improved dimensional stability and other structural benefits.
In the absence of ‘EDH’ technology in India so far, the above enumerated benefits could not be availed of so far. Now, however this technology is readily available to VAEVKN through its partners VAE and JEZ
