The crankshaft uses a high-frequency induction heating power supply for improved heat treatment. What is the result?

When the crankshaft is working, the crankshaft relies on the periodically changing fuel explosion in the cylinder to drive the crankshaft to rotate at high speed. The stress it experiences is quite complex. It mainly bears the bending moment and torque of large loads, as well as the wear and tear of bearings. Therefore, crankshafts are often required to have high rigidity and fatigue strength as well as good wear resistance. There are always various defects in the crankshaft when using traditional equipment for heat treatment. Therefore, a new high-frequency induction heating power supply is used for an improved heat treatment process. Today, the editor will not tell you the specific improvement process, but I will tell you the results of the improvement.

Through process improvement and equipment modification, the author used 100 crankshafts to conduct the test. The User Service Science and Technology Committee assigned a dedicated person to be responsible and track the test results throughout the process. The final results statistics are shown in the table below.

After improving the process and equipment transformation, the normalizing hardness of the crankshaft has been steadily increased, meeting user requirements; the implementation of this plan has increased the crankshaft's share in the high-end market and greatly increased product profit margins; this idea and improvement method can be used Parts with similar quality issues.

From the above description, it can be seen that after the crankshaft is heat treated using an improved process, its performance is good and meets its working needs. If you want to know more about the specific crankshaft induction heat treatment process, please feel free to contact us.
