- W2380777632 abstract "Shenyang Hunnan modern tram project is the first modern tram rail transit network in China. Groove rail was adopted in the line project for laying CWR track. However,due to the groove in the rail head,no mature rail welding method was available for groove rail. According to the characteristics of 59R2 groove rail section,a sand block which matches the shape of groove of the rail was designed to solve the difficult problem of groove welding and grinding. Test of slow bend strength,fatigue performance, hardness,metallographic structure,etc. were performed on 59R2 groove rail welding joints,and the results showed that all the performance can meet the technical requirements. The groove rail thermit welding technology was applied in Shenyang modern tram rail welding project and demonstrated its stable quality and convenient construction." @default.
