| This induction hardening equipment is also called impact hardening equipment or pulse hardening equipment. Our company manufactures and sells equipment that uses high frequency to instantaneously harden materials in units of 1/10,000 seconds. The frequency is 27MHz and the plate outputs up to 5kW instantly, making it possible to harden the tip of the saw blade. It can also be used for metals that require impact heating only at the tip or locally. |
| With this quenching method, there is no need to cool the material by soaking it in water or oil after heating. Since the power-on time is extremely short, quenching can be done as is. Since the frequency is 27MHz, the surface is mainly heated. You can see the metal glow yellow even after heating for just a few thousandths of a second. (The color varies depending on the temperature.) By quenching, the Vickers hardness (Hv) increases to around 1000. |
| The oscillation frequency may deviate slightly from the target frequency
due to vacuum tube self-excitation oscillation. |
