Latest company news about What is the cooling device and cooling method for railway wheels?

The company has developed a railway wheel cooling device, a cooling method and a preparation method, which belong to the technical field of railway wheels. The device includes a quenching table and a plurality of spray guns uniformly arranged along its circumference, and the spray guns include a water outlet panel and a water inlet branch pipe. The water outlet panel is provided with large nozzles and small nozzles with different diameters. The small nozzles are controlled by a branch pipe alone, and the large nozzles are divided into upper and lower parts, which are controlled by different branch pipes. It can easily adjust the strength of the cooling water sprayed to the wheel, and improve the cooling uniformity of the wheel rim in the radial and axial directions. The cooling method adopts the above-mentioned cooling device to heat-treat and cool the wheel when preparing the wheel, thereby effectively enhancing the hardness uniformity of the wheel rim and improving the service performance of the wheel. The preparation method adopts the above-mentioned cooling method to heat-treat and cool the wheel during preparation, and can prepare a wheel with high uniformity of rim hardness.
