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
