High Quality IGBT Induction Heating Machine Induction coils
Induction coil design
It is within the induction coil that the varying magnetic field required for induction heating is developed through the flow of alternating current. So coil design is one of the most important aspects of the overall system. A well-designed coil provides the proper heating pattern for your part and maximizes the efficiency of the induction heating power supply, while still allowing easy insertion and removal of the part.
Induction coils are normally made of copper tubing - an extremely good conductor of heat and electricity - with a diameter of 1/8" to 3/16"; larger copper coil assemblies are made for applications such as strip metal heating and pipe heating. Induction coils are usually cooled by circulating water, and are most often custom-made to fit the shape and size of the part to be heated. So coils can have single or multiple turns; have a helical, round or square shape; or be designed as internal (part inside coil) or external (part adjacent to coil). There is a proportional relationship between the amount of current flow and distance between the coil and part. Placing the part close to the coil increases the flow of current and the amount of heat induced in the part. This relationship is referred to as the coupling efficiency of the coil.
1. It adopts the most advanced MOS, IGBT frequency conversion control technologies to ensure the high efficiency and maximum output power.
2. It has the constant current and power control function, which can significantly optimize metal heating process, realize the high efficient and fast heating and bring into play the superior performance of the products.
3. It has the function of three-stage time setting represented by heating-heat preservation-cooling. Furthermore, the power for heating and heat preservation is available for independent regulation, which can facilitate the heating and heat preservation, which is applicable to places requiring bulking and repeated heating.
4. A maximum ten types fault protection and display of over-current, over-voltage, water shortage and phase missing can provide higher reliability and durability.
5. It is safe and reliable, and requires no equipments of ten thousand voltage, and thus can ensure the safe operation.
6. The comprehensive full load design is available for 24-hour continuous operation.
7. It is available for ultraviolet temperature detection, which can realize the automatic control of temperature, improve the heating performance and simplify the manual operation.
