What is a high frequency machine?
The high frequency machine is the induction heating equipment with the highest heating efficiency, the fastest speed, low energy consumption and environmental protection for metal materials. Full name "high frequency induction heating machine, high frequency machine and high frequency heating machine, high frequency induction heating equipment, high frequency induction heating equipment, high-frequency heating power supply, high frequency power supply, high frequency welding machine, high frequency induction heating machine, high frequency induction heater (welding), etc., and intermediate frequency induction heating equipment, ultra-high frequency induction heating equipment, etc. It is widely used.
What is the principle of the high frequency machine
1. The high frequency current flow of the high-frequency machine is wound into a ring or other shaped heating coil (usually made of red copper tube). Thus, a strong magnetic beam with instantaneous change of polarity is generated in the coil. If the heated object such as metal is placed in the coil, the magnetic beam will penetrate through the heated object. In the interior of the heated object in the opposite direction of the heating current, a large eddy current will be generated. Because there is resistance in the object being heated, a lot of joule heat is generated, causing the temperature of the object itself to rise rapidly. To achieve the purpose of heating all metal materials.
2. In the high frequency machine, by a set of unique electronic lines, the 50Hz low-frequency ac power input from the external power supply will be converted into high-frequency ac power above 20000Hz; After the high-frequency current is added to the inductive coil, the principle of electromagnetic induction is used to convert it into a high-frequency magnetic field and act on the metal object in the magnetic field. Using eddy current effect, generated in the metal objects is proportional to the magnetic field strength of the induced current, the current in the metal flow in the body, can with the help of the inherent internal resistance, using the current heating principle to generate heat, the heat is generated within the object directly, so, this way of heating, fast speed, high efficiency. If needed, it can melt any metal in an instant. Moreover, its heating rate and temperature are controllable.
The principle of high frequency machine is widely used. The high frequency machine is the induction heating equipment with the highest heating efficiency, the fastest speed, low energy consumption and environmental protection for metal materials.
