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-

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.

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.

The speed and quality o the induction heating pro-

parameters, line speeds and quenching systems.

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

tional lters areavailable thatcontinuously remove

scaling rom the quench water.

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.
