What should be considered when purchasing an induction heating furnace medium frequency induction heating power supply?

Time: 2019-05-15

Only the induction heating furnace intermediate frequency power supply is purchased, and the capacitor and induction coil or heating furnace are designed according to the customer's heating workpiece and heating requirements. Therefore, customers who order or consult need to provide the following information:

(1) The workpiece material to be heated, size, shape and size: large workpiece, bar material, solid material, induction heating equipment with high relative power and low frequency; small workpiece, pipe, plate, gear, etc., select relative power Small, high frequency induction heating equipment.

(2) Depth and area required for heating: deep heating depth, large area, overall heating, should use high-intensity, low-frequency induction heating equipment; shallow heating depth, small area, local heating, low relative power, high frequency Induction heating equipment. The heating rate required for the required heating rate is fast, and an induction heating device having a relatively large power and a relatively high frequency should be selected.

(3) Continuous working time of equipment: continuous working time is long, relatively inductive heating equipment with slightly higher power.

(4) The purpose of heating and heating temperature, as well as heating time requirements; is it diathermy or surface heating? If the surface is heated, what is the depth of heating? and many more

(5) Connection distance between the sensing component and the device: the connection length is long, and even the water-cooled cable connection is needed. The induction heating device with larger power should be used relatively.

(6) Is there any limit to the way and size of the induction coil? For example, from internal heating or external heating? Is the induction loop closed or open? Is there any metal material that is easy to sense within 100mm around the induction coil? and many more.

(7) Process requirements: Generally speaking, quenching, welding and other processes can be relatively small in power selection, higher in frequency selection; annealing, tempering and other processes, with higher relative power selection and lower frequency selection; red flushing and heat For calcination, smelting, etc., a process requiring good heat transfer is required, and the power should be selected to be larger and the frequency selected lower.

(8) Material of the workpiece: The relative power of the high melting point of the metal material is larger, the relative power of the lower melting point is smaller; the power of the smaller resistivity is larger, and the power of the larger resistivity is smaller.

(9) Is there any specific requirement for the frequency?

(10) Heating atmosphere: Is it still in the vacuum furnace? Is there a protective gas?
