Walking wheels are used to support the weight of tractors and agricultural implements, and to ensure that the machines run along the ground. During the working process, the walking wheel has to bear huge friction force. For this reason, we often use medium frequency induction heating machine for quenching heat treatment to improve the hardness, wear resistance and service life of the walking wheel, and the effect is very good.
After the walking wheel is quenched by the medium frequency induction heating machine, there will be a layer of hardened layer on its surface, about 3-5mm. It is precisely because of this layer of hardened layer that the hardness of the walking wheel is greatly increased, which meets its working requirements. The walking wheels on ordinary tractors can be quenched and heat-treated by our company's 200kw medium-frequency induction heating machine.
Medium frequency induction heating machine is generally used for quenching heat treatment of workpieces with deep quenching depth. When it performs quenching heat treatment on the walking wheel, the heating speed is very fast, which effectively avoids the phenomenon of oxidation and decarburization of the walking wheel during the quenching process, ensures the quenching effect of the walking wheel, and makes the hardened surface of the walking wheel after quenching. The thicker ductile area has better compressive internal stress, which makes the fatigue resistance and breaking capacity of the road wheel higher. What's better is that it can carry out local quenching heat treatment on the traveling wheel, and can also carry out overall quenching heat treatment, which can meet the heating requirements of different customers.
