[0002] Heat treatment is an important process of wheel manufacturing, among which the quenching process is the key to the whole heat treatment, which is directly related to the comprehensive performance of the wheel. At present, all wheels at home and abroad adopt full tread quenching. In this way, the quenching area is fixed and cannot be adjusted. In addition to the nozzle water cooling, it is also cooled by the quenching water flowing down from the upper part of the tread, resulting in a large difference in the distribution of the strength and hardness of the wheel, which is not suitable for wheels that have special requirements for uniformity of strength and hardness.

The invention discloses an adjustable quenching control device which comprises a nozzle used for quenching and water baffles used for shielding the nozzle to control the quenching water amount and thequenching area, the water baffles are installed on the periphery of the nozzle, positioning rods are arranged on the periphery of the nozzle, and the water baffles are connected to the positioning rods in a sliding manner and can move along the positioning rods. By means of the adjustable quenching control device and the quenching manner thereof, the upper water baffle, the lower water baffle, the left water baffle and the right water baffle are arranged and can move along the positioning rods, and the needed quenching nozzle form is obtained by shielding nozzle holes in different directions.The adjustable quenching control device further comprises supporting frames used for supporting the water baffles, the supporting frames are fixedly installed on the periphery of the nozzle, and thepositioning rods are installed on the supporting frames. Sleeve holes are formed in the two end portions of the water baffles, are fixedly connected to the water baffles and are connected to the positioning rods in a sliding and sleeving manner. The adjustable quenching control device further comprises springs, the positioning rods are sleeved with the springs, and the two ends of the springs areconnected with the sleeve holes in the two ends of the water baffles correspondingly. The invention further discloses a quenching manner of the adjustable quenching control device.
Description
technical field [0001] The invention belongs to the technical field of locomotive wheels, and in particular relates to an adjustable quenching control device and a quenching method thereof. Background technique [0002] Heat treatment is an important process of wheel manufacturing, among which the quenching process is the key to the whole heat treatment, which is directly related to the comprehensive performance of the wheel. At present, all wheels at home and abroad adopt full tread quenching. In this way, the quenching area is fixed and cannot be adjusted. In addition to nozzle water cooling, it is also cooled by quenching water flowing down from the top of the tread, resulting in large differences in the distribution of wheel strength and hardness, which is not suitable for wheels that have special requirements for uniformity of strength and hardness. Therefore, it is necessary to design a device with controllable quenching water volume and quenching area. Contents of t...
