"Our premium heat-treated rail is produced using a unique patented process which ensures it has exceptional wear resistance”
Tata Steel has recently signed a contract to supply highly wear-resistant rail for the Crossrail project in London.
"Our premium heat-treated rail is produced using a unique patented process which ensures it has exceptional wear resistance,” said, Gérard Glas, Rail Sector Head, Tata Steel.
"Rather than using traditional methods of heating and cooling, Tata Steel has developed a system where the rail moves through an induction furnace which uses an electromagnetic field to heat the steel to 950°C. The rail is then rapidly cooled using compressed air. The resulting uniquely low residual stresses provide further protection against risk of rail failure compared to other in-line heat treatment processes," Glas added.
The Crossrail route is expected to serve 40 stations and travel more than 100km from Reading and Heathrow. Tata Steel will supply the project with more than 57km of its heat treated, wear-resistant rail.
“In total 7,000 tonnes of Tata Steel rail will be used to create one of Europe's largest railway and infrastructure projects,” according to the company statement.
