How Does the System Enhance the Hardness and Wear Resistance of Excavator Bucket Pins?

The Induction Power Supply generates high-frequency alternating current, which is supplied to the output transformer further to induction coil. The coil is designed to produce an intense electromagnetic field, which is responsible for heating the surface of the excavator bucket pins inside coil.

A bucket pin is precisely positioned inside the induction coil during the Induction Heat Treating process. Once the Induction Hardening Machine starts up, the induction coil starts moving progressively and electromagnetic field generated by the coil rapidly heats the surface layer of the pin. 

After reaching the desired temperature, the quenching system starts to work. The pin is quickly cooled with quenching media sprayed from the quenching coil, which usually contains a specialized quenching medium such as oil, water or polymer. Rapid cooling of the heated surface helps transform the metal structure and form a hardened layer. The quenching process significantly improves the hardness, wear resistance and overall strength of the excavator bucket pin. CNC Control systems in Induction Heat Treatment systems precisely regulate the heating and cooling processes. Operators can set specific parameters such as heating time, temperature and traveling speed of induction coil, flow and pressure of quenching medium for consistent and optimized hardening pattern.
