manufacture of Crane rail QU120 QU100 qu80 steel rails B/T 5055-2014 standard
The rails are made of killed steel from open hearth smelting.
A production process that does not produce white spots in the rail should be used.
Mechanical properties
The tensile strength of the rail is not less than 90 kg/mm.
Surface Quality of Grade of 900A Din536 A120 Steel Rail for Gantry Crane
There shall be no cracks, folds, scars, bubbles and inclusions on the rail surface. Indentations, pits and scratches with a depth not greater than the allowable negative deviation value of the rail size and hairlines with a depth not greater than 1 mm are allowed.
There shall be no residual cracks, delaminations and shrinkage holes on the end face of the rail.
The end face of the rail shall be cut straight, and the skew of the end face shall not exceed 5 mm in any direction. Burrs with a length of not less than 4 mm should be removed.
The surface defects of the rail are allowed to be cleaned longitudinally with an air shovel, and the cleaning depth (calculated on one side) shall not be greater than the allowable negative deviation of the size.
Rail surface defects are not allowed to be repaired or filled by welding
Section size of QU100 rail: rail height: 150mm, bottom width: 150mm, head width: 100mm, thickness: 38mm, weight: 88.96kg/
QU100 rail material: U71Mn material, 45Mn material, 50Mn material rail
QU100 rail standard: YB/T5055-93
QU100 rail length: 12 meters/piece, 12.5 meters/piece
shape of Crane rail QU120 QU100 qu80 steel rails B/T 5055-2014 standard
The lateral curvature of the rail shall not be greater than 1.5 mm per meter, and the total curvature shall not be greater than 8 mm.
The total curvature of the rails in the upper and lower directions shall not exceed 6 mm.
The end of the rail should not be bent more than 1 mm within 0.5 m.
The QU120 crane rail is limited by the capacity of the straightening equipment. The degree of curvature is determined by the customer.
The torsion of the rail shall not be greater than 1/10 000 of the full length of the rail.
The asymmetry of the rail cross section and the vertical axis: the bottom of the rail should not be larger than 2 mm, and the head of the rail should not be larger than 0.6 mm.
The bottom of the rail should not be recessed. The center of the rail bottom should not protrude more than 0.5 mm from the two sides.
weight
The rails are delivered according to the theoretical weight.
