What is an intermediate frequency furnace What is the difference between an intermediate frequency furnace and a high frequency furnace-Kehua

Corresponding equipment is used in metal processing and smelting. For example, intermediate frequency furnaces and high-frequency furnaces are the most commonly used equipment, but the difference between these two types of equipment is still very large. Next, Kehua will tell you what an intermediate frequency furnace is. What is the difference between an intermediate frequency furnace and a high frequency furnace? What is an intermediate frequency furnace and a high frequency furnace? It converts the three-phase power frequency alternating current into direct current after rectification, and then converts the direct current into an adjustable intermediate frequency current, which supplies the intermediate frequency alternating current flowing through the capacitor and the induction coil, and generates high density in the induction coil. The magnetic line of force is cut, and the metal material contained in the induction coil is cut, resulting in a large eddy current in the metal material. Kehua believes that the medium frequency induction furnace has the advantages of high thermal efficiency, short smelting time, less burning loss of alloy elements, wide range of smelting materials, less environmental pollution, and can accurately control the temperature and composition of molten metal. What is the difference between the intermediate frequency furnace and the high frequency furnace? Under normal conditions, the current frequency is between 100 and 500 kHz; 2. The higher the frequency, the lower the heat penetration capacity; 3. The effective hardening depth of the intermediate frequency furnace is 2 to 10 mm, and the main application range is the requirement for quenching The hard layer requires deeper parts; the effective hardening depth of the high-frequency furnace is between 0.5 and 2 mm. 4. The intermediate frequency furnace can be used to smelt various metals ranging from five kilograms to sixty tons; high-frequency induction heating is suitable for smelting precious metals ranging from one to five kilograms. 5. The intermediate frequency furnace is large in size and mature in technology; the high-frequency furnace is small in size, fast in operation and cheap in price. Although the intermediate frequency furnace and the high frequency furnace are both commonly used smelting equipment, the difference between the two is obvious, such as price, volume, smelting efficiency, etc., there are great differences.
