Howtomakepremiumproduct.
And charge premium prices.An integrated induction hardening and tempering solution let you easily produce premium grade
chaina product that commands premium prices in international markets.
In a globalized economy ull o low-priced commodi-
ties,theabilitytomakepremium-gradeproductsis
crucialtoremainingcompetitive.Forchainmakers,
this means producing chain to the tough standards
set by the liting, oshore construction, logging, ship-
ping and fsheries industries, etc.

An optical heat sensor measures chain temperature. The
sensor is just one of many quality assurance features
available for an EFD Induction chain treatment solution.
The control screen gives a full visual overview of the chain
heat treatment process. All aspects of the process can be
controlled from the control panel.

Morechain.
Moregain.An in-line hardening/tempering system rom EFD In-
duction streamlines production. The chain loads di-
rectly rom its magazine into the system, and emerg-
es at the other end as hardened and tempered chain.

need or chain storage and transportation. Features
such as control plates and guiding cones at the coil

The speed and quality o the induction heating pro-
cess is ensured by sophisticated yet easy-to-use con-
trolsoftware.Fromasingleinteractivepaneltheop-
erator is, among other things, able to control heating
parameters, line speeds and quenching systems.
The control systemwhich eatures a multilingual
control panelcan store data or more than 100 di-
erent chain types.

equipment changes are necessary.
Our heat treatment systems typically include two
cooling systems: one or the induction heaters, one
or chain quenching. Both systems use normal ac-
tory water in their primary cooling circuits. The sys-
tems are low maintenance, low pressure solutions

den pressure drop in the mains water supply. Op-
tional lters areavailable thatcontinuously remove
scaling rom the quench water.

hands-on training at the start-up of
a new chain heat treatment solution.
Above, chain is extracted from its
magazine. It will emerge hardenedand tempered from the end of the
line and be automatically fed to a
waiting magazine or pallet.
