Travel wheel, also known as crane wheel, crane wheel, forged steel wheel, etc., after reasonable quenching and heat treatment, the hardness, toughness, wear resistance, etc. of the travel wheel are increased by 2-3 times.

The main configuration of the travel wheel quenching equipment includes:

1. One set of super audio frequency quenching machine (160kw) 2. Three sets of random inductors (customized according to user's workpiece) 3. One foot switch.

Travel wheel is a classification of forgings, mainly used for gantry cranes - port machinery - bridge cranes - mining machinery, etc. Also known as: crane wheel, crane wheel, port machinery wheel, wheel forging, wheel forging, forged steel wheel, etc.! It is a relatively easy to damage part. According to the use characteristics of the crane, the wheel tread is required to have high hardness, and a certain depth of hardened layer and transition layer (depth>10mm, hardness HRC40-48) to improve the bearing capacity, wear resistance and contact fatigue resistance. At the same time, the base structure is required to have good comprehensive mechanical properties and good organizational state, hardness should be HBS187~229, so that it has high toughness, improve impact resistance and crack resistance. In order to achieve this characteristic, the surface heat treatment of the travel wheel must be in place.

Usually, 120KW quenching equipment is used to ensure the tightness of the travel wheel quenching and improve the surface hardness and wear resistance.

Inductor: using profiling inductor, because the heating is plane or groove quenching, so it is necessary to install a magnetic conductor, the quenching process is heating while spraying water, completed at one time.

In order to ensure the uniform hardness of the travel wheel quenching, the quenching process must be completed with the help of tooling. The function of the tooling is to make the travel wheel do uniform axial rotation, and the rotation can be steplessly adjusted according to the size and requirements of the travel wheel.

The quenching process is that the quenching equipment cooperates with the tooling to scan and heat the surface of the workpiece to be quenched while the workpiece is rotating. The rear part of the inductor is equipped with a water spray device. The rotation, heating and water spraying process of the travel wheel are all controlled by the CNC system according to the process requirements.
