INDUCTION HARDENING

Induction hardening is a process that is used to harden, bonding or soften metals or other conductive materials.

The induction heating systems do not burn as traditional fossil fuels. Induction is a clean, non-polluting process that helps protect the environment.

In induction hardening the steels used usually contain a carbon percentage between 0.30% and 0.70% (“hypoeutectoid steels”).

This process is based on Faraday’s law implies that when an alternating current is applied to the primary of a transformer an electromagnetic field is created. When the secondary is introduced in this field an electric current is induced.

In a basic configuration of induction hardening, a power supply generates an alternating current through an inductor within which the part to be treated is placed. The inductor acts as the transformer primary and secondary circuit as the part. When the metal part is crossed by the magnetic field,”Foucault” currents are induced in them flowing against the electrical resistivity of this. This creates a localized and precise heat without direct contact between the part and the inductor. This effect occurs both magnetic parts as nonmagnetic and is known as the “Joule” effect.

Induction Hardening can be done in two ways:

In STATIC: Consists on locating the piece opposite the inductor without dragging during operation.

PROGRESSIVE ( By Parade): Consists on tour the part performing continuous operation or moving the workpiece or inductor.

ADVANTAGES OF INDUCTION HARDENING

1/ You can treat a particular part of the piece (Quenching Profile).

2/ Power applied Management. Frequency control and heating times.

3/ Control of cooling parameters.

4/ Energy saving.

5/ Temperature control and location

6/Possibilities of Harden different dimensions of parts and inner diameters.

7/Different types of frequency and power depending on the required lid depth.

Nuestra historia

APRIM is established in 1965 with a core activity focused on the manufacture and machining of parts and assemblies destined for the Automotive Industry and Transport, APRIM then begins production. Over time, APRIM has evolved to offer a wide diversification of services including manufacturing and assembly kits sets with not only mechanical components, also pneumatic, electric, electronic, etc.
