Induction Hardening- An Efficient Heat Treatment Method by hkksew3563rd


									Over the past few decades or so, there has been a pervasive technological growth in
almost every sector. Notwithstanding the industry new innovations and unique new
devices have changed the way we look at things across all industries and verticals, be
it information technology, health, or for that matter heavy metal. This growth trend
has also brought a new and valuable heating technology called induction hardening
that is now popular all over the world. This new technology is used to harden metal
components, and although it is not a difficult process there are things that have to be
kept in mind to conduct the process successfully.

Of course, there are host of other treatment methods used to heat metal, for example
annealing, tempering, homogenizing, carbo-nitriding, are all processes that can be
used to harden wrought iron, steel, alloys, die steels, etc. But, induction hardening
probably is the most effective method. In this type of heat treatment the chemistry of
the metal component becomes a deciding factor in hardening or quenching the metal.
Before beginning the process it is important to take note of the optimum temperature
that needs to be delivered to it; also, if the metal is prone to cooling down too fast.
Mostly, this process is used to harden steel and steel alloys. The process involves
heating the metal by inducting high temperatures to it and consequently quenching it
with a solvent, so that the core of the metal remains soft giving it flexibility, while the
surface becomes hard. The aim is to significantly improve the durability of the metal
and to make them suitable to be used in the production of springs, gears, and shafts
for the heavy industries.

Principally, there are two ways of conducting the induction hardening process, the
traverse hardening process and the single-shot hardening process. In the traverse
hardening process the metal object that has to be heat-treated is passed through an
induction coil several times in a series, while a quenching spray is simultaneously
used to layer the surface of the metal with a solvent liquid. This process of hardening
is used across industries to manufacture a variety of shaft type metal objects like
steering components, power tool shafts, and drive shafts. Also, this process is
instrumental in manufacturing metal objects that have a sharp edge, like lawnmower
bottom blades, hacksaw blades, paper knives, and leather knives. Quench rings are
used in this process as an integral part of the system.

Single-shot hardening process also uses an induction coil. But in this process, the
metal object is inserted in to the coil and either held still or rotated for prefixed time
duration. In the industry this process is used to harden small tools, the edges of
complex shaped tools, and the flat-faces of tools like hammers. For the standard
induction hardening procedure a high frequency power source and a work coil that
generates alternating magnetic field are required to be able to successfully conduct
heat treatment on a work object that conducts electricity. The process can be intricate
and if you’re looking for a company that provides these services be sure to only
employ a company that has a valid license and uses the right kind of equipments for
the purpose.
 Induction hardening is a standardized industry procedure for the heat treatment of
metal objects. provides professional and customized service
solutions for all kinds of requirements related to the treatment and hardening of metal
tools and gears.
