Manganese Crossing EHZ CENTRO MN13
The managanese crossing "EHZ CENTRO MN13" is a common monoblock crossing.
The complete central part of the crossing is cast in one block from high-manganese steel. This part corresponds to a monoblock crossing, with the only exception of the length of the fishing table. Closure rails are flash-butt welded to the four ends of the central block using a special flash-butt welding technique (intermediate piece welding). The bearing surfaces (seat of the plates) as well as the complete area of the running and head surfaces are milled and/or planed. The thus achieved manufacturing accuracy facilitates optimal wheel overrun and interchangeability of crossings on existing sets of plates.
Materials and quality inspection:
- Rail in line with rails steel within turnout
- Crossing: High-manganese steel (13% Mn) according to EN 15689
- Visual and geometric check
- Penetration test: Flash-butt weld
- Radiography test: Prototypes
- Mn13 casting according to EN 15689
