Rail shoulders are cast in the concrete railway sleepers to fix elastic rail clips and steel rail. According to different production processes, rail shoulders can be divided into cast-in rail shoulder and weld-on shoulder, and both of the two types of rail shoulders have the function of fixing elastic rail clips and protecting the rail clips from being stolen.
Cast in Rail Shoulders
Cast in Shoulder is made by casting from iron, and such shoulder is used by being pre-embedded in the concrete sleepers and works with the elastic clip to fasten the rail.
For materials, cast in shoulder includes 3 types: M.C.I. shoulder by malleable iron and S.G.C.I. shoulder by malleable iron and S.G.C.I. shoulder by spheroid graphite iron.
Main Material Technical Parameter of Cast in Rail Shoulders
| Material | Tensile Strength(Mpa) | Yield Strength(Mpa) | Elongation(%) |
| QT400-15(GGG40) | 400 | 250 | 15 |
| QT450-10(GGG45) | 450 | 310 | 10 |
| QT500-7 (GGG50) | 500 | 320 | 7 |
Other materials available: QT600-3,QT700-2,ZG25,ZG35,ZG45 and so on.
Standard: GB/T 1348-1988, NF EN 1563(1997), ISO1038, DIN 1693, JIS G5502 (2001), KS D 4302, GOST 7293(1985) or BS EN 1563(1997).
Weld-on Shoulder:
Weld-on shoulder is made by hot forging, and such shoulder is used for places where standard sleepers are unable to be easily used so the shoulders need to be welded on the flat steel base plates. In this way, it can fabricates the rail retaining units on both the steel ties and base plates, according to AREMA standard always.
Weld-on shoulders can be applied for clips with a range of 30lbs to 113lbs.
Special rail shoulder
Such kind of shoulder can be produced by hot forging as well, to be used together with rail clip bolts and special rail clips to fasten the rail, with material of low or mid carbon steels.
