What is Induction Hardening?
Induction heating machine is widely used in much different kind of industrial metal hardening and forging field. So, what is induction hardening? How can induction heater be able to achieve the purpose of metal hardening? Now, let’s just spend a few time to get through the following information about induction hardening.
Induction hardening is a form of non-contact heat treatment that uses electromagnetic induction to produce heat in metal parts internally. A strong alternating magnetic field surrounds a conductive metal piece, producing an electric current that creates heat in the surface of the material being treated. After the metal is being heated, then it will be quenched, forming a martensitic structure on the surface which is tougher than the base metal.
KEXIN induction hardening machine is mainly and commonly used in carbon and alloy steels. Following are the advantages of using induction hardening:
- Fast Speed of process – There is no required holding time; thus, you will get the higher production rates.
- Variable hardening depths as per customers’requirements.
- There is no decarburizing and scaling
As the induction hardening process is entirely electromagnetic in nature, different settings may be manipulated to suit different steel bar diameters and desired case depths with very good precision. It is quietly important for some metal parts which require external toughness to hold shapes, which range from gears, shafts, and springs to knives and blades, etc.
Induction hardening results in materials with a high level of surface hardness, which is capable of handling extremely high loads. It is particularly useful for parts that experience impact forces and torsional loading. Typical applications of this nature include suspensions, engine components, and powertrains. It is because magnetic fields can also be confined to specific areas, the induction hardening process can be used for selective hardening of certain parts.
Kexin has over 10 years of experience in metalwork, including induction heating and furnace treatment, manual and CNC machining and welding. We have strict documentation of all processes and adherence to different customers’ specifications, so that to produce exact duplicates of specific parts, resulting in good business relationship with our customers.
