Overview of high-frequency quenching equipment for rocker arms
The rocker arm high-frequency quenching equipment is a device that uses high-frequency current to rapidly heat the surface of metal materials, and is widely used in fields such as metal heat treatment, quenching, and heat transfer. This device adopts advanced IGBT modules, which have the characteristics of high heating efficiency, energy saving and environmental protection, and easy operation. Next, we will delve into the working principle, outstanding advantages, technical parameters, application scope, as well as design and manufacturing details of the high-frequency quenching equipment for rocker arms.
working principle
The core principle of the high-frequency quenching equipment for rocker arms is electromagnetic induction. When an alternating current flows through a conductor (usually a copper tube) that is coiled into a ring shape, a magnetic beam is generated. If a metal is placed in it, the magnetic beam will penetrate the metal body and generate eddy currents in the opposite direction to the spin direction of the magnetic beam, that is, induced currents. Induced current can cause metal to generate heat, thereby achieving the purpose of heating.
