Piston rings are widely used in various power machinery, such as steam engines, diesel engines, gasoline engines, compressors, hydraulic machines, etc. It is the core component inside the fuel engine, and it completes the sealing of fuel gas together with the cylinder, piston, cylinder wall, etc. During the working process, the piston ring has to bear huge frictional force. Therefore, the piston ring is usually required to have high hardness, high wear resistance and long service life in the work. In order to meet the above requirements, our customer purchased a medium-frequency induction heating machine to quench and heat-treat the piston ring, and the effect is very good.
The medium frequency induction heating machine is used to quench the piston ring, the speed is very fast, and the required temperature is reached in a short time, which avoids the occurrence of oxidation and decarburization, ensures the heat treatment effect of the piston ring, and makes the heat treatment There is a thicker tough area under the hard layer on the surface of the piston ring, which has better compressive internal stress, so that the fatigue resistance and breaking capacity of the workpiece are higher, which meets the needs of the work.
The medium frequency induction heating machine adopts IGBT transistors manufactured by German Siemens technology. The equipment starts quickly, has strong heating capacity, fast speed, and stable operation; high power factor configuration, no need to configure other auxiliary devices, and can run for 24 hours under full load. without any safety hazard. Based on this, more and more manufacturers use medium frequency induction heating machines to quench and heat treat workpieces.
