COMPRESSED AIR PETROL PRE HEATING EQUIPMENT

This system is designed for pre-heating the rail ends for welding by the alumino-thermic process. The joint is preheated for a moderately low period thereby achieving better metallurgical characteristics by minimizing the width of the heat affected zone.

Preheating time required for SKV Process

Rail SectionPreheating Time
UIC 60 Kg/m 4 minutes
52 Kg/m4 minutes
90 R3 minutes
75 R3 minutes


TECHNICAL SPECIFICATION
Maximum Air Pressure0.5 Bar
Air discharge70 m3/hr
Overall DimensionsL = 1250, W = 500, H = 950 mm.
Operating pressure for preheating0.15 to 0.2 bar
Gross weight113 Kg.

Special Feature & Advantages

Human error is eliminated as the system is mechanized.
System requires considerably less time for preheating of rail ends and thereby reduces the block time.
Improved metallurgical characteristics are created as the heat affected zone in the weld is narrowed.
System requires petrol as fuel, hence oxygen and propane cylinders are not required to be
      carried to site.
