Product introduction

This railway wheel applied a new cooling device, cooling method and preparation method belong to the technical field of railway wheels. The device includes a quenching table and a plurality of spray guns evenly arranged along the circumferential direction thereof. The spray gun includes a water outlet panel and a water inlet branch pipe. The water outlet panel is provided with a large spray eye and a small spray eye with different diameters, wherein the small spray eye is independently controlled by a branch pipe, and the large spray eye is divided into upper and lower parts, and the water outlet is controlled by different branch pipes respectively. It can conveniently adjust the strength of the cooling water sprayed to the wheels, and improve the cooling uniformity of the wheel rims in the radial and axial directions. This cooling method adopts the above cooling device to heat-treat and cool the wheels when preparing the wheels, which effectively strengthens the uniformity of the hardness of the wheel rim and improves the performance of the wheels. The preparation method adopts the above cooling method to heat-treat and cool the wheels during the preparation, and wheels with high rim hardness uniformity can be prepared.
