company news about What are the advantages of a railway wheel heat treatment furnace?

The company has developed a railway wheel heat treatment furnace, in which the structure of the induction heating device is to set an induction heating coil on the periphery of the tread of the railway wheel, and the inner side of the rim of the railway wheel and the inner side of the rim to the spokes. At the corresponding position of the transition area of the plate, an induction heating compensation coil is set. The invention also discloses a heat treatment process method of the heat treatment furnace. By adopting the above technical scheme, the technological goals of high strength and high toughness of the rim and low strength and high toughness of the web are achieved. The heating speed of the two-phase region is very fast, and the residence time of the austenite region is very short, which is conducive to the uniform refinement of the grains and the improvement of the toughness of the rim. The rapid heating of the wheel rim can be achieved, and the temperature of the web is kept below Ac3 while the rim is completely austenitized. The invention has the advantages of fast start-up, fast heating speed, easy temperature control, high heating efficiency, good process repeatability, good workpiece surface quality, environmental protection and the like.
