An intermittent quenching method for railway wheels belongs to the
field of heat treatment of railway wheels. The present invention is
carried out according to the following steps: S1, heating the
entire wheel to complete austenitization; S2, alternately
performing water cooling and air cooling on the wheel, so that the
entire rim area forms a uniform fine pearlite+ferrite structure;
wherein cooling The process includes the first stage and the second
stage, the water volume V1 in the first stage is less than the
water volume V2 in the second stage, the alternating times of
circulating water/air cooling in the first stage is N1, and the
alternating times of circulating water/air cooling in the second
stage is N2, N1>N2. The invention overcomes the problem of poor
performance of the wheel caused by the conventional quenching
method in the prior art, can effectively avoid the formation of an
abnormal structure caused by the conventional quenching method in
the near surface layer of the tread, reduce the depth of the
abnormal structure as much as possible, thereby effectively
improving the whole life cycle of the wheel Internal service
performance, extending the service life of the wheel.
A railway wheel storage device, the storage device comprises: an
inverted U-shaped pillar with hooks, a plurality of pillars
uniformly distributed on the circumference of the two sides of the
pillar with hooks in the circumferential direction, and a plurality
of pillars distributed in the vertical direction at intervals
between the pillars with hooks and each An annular inner support
frame on the inner side of the column, and an annular outer support
frame arranged at the bottom of the column with hook and each
column; wherein, the column with hook and the bottom of each column
are located in the same horizontal plane, and the outer support
frame is connected with the column with hook and the bottom of each
column. The bottom of the upright column is fixedly connected into
one body; a plurality of inner support frames are fixedly connected
with the hooked column and each upright column to form a
cylindrical whole. When the utility model is used, only the wheel
hub hole of the railway wheel needs to be inserted into the
cylindrical part formed by the hook strut and each upright column
in sequence from the top with the hook strut, and at least 4-5
wheels can be stored, which occupies less space and has high
storage efficiency. The utility model can be widely used in the
storage and transportation of railway wheels and wheel-shaped
accessories with center holes
Strength of carbon steel railroad wheels and axles for train bogies
