▲ ▲ QED galvanising and Galfan lines
QED specialises in equipment for
heat-treating, cleaning and coating of
steel wire. Custom designed and built,
its high-speed lines are for galvanising,
Galfan®, patenting, annealing, and oil
tempering processes.
Combining innovative design concepts
with 30 years practical experience, QED
has developed a range of products and
equipment that is both technologically
advanced and ruggedly dependable.
With a view to improved efficiency and
to minimise environmental impact, QED
has developed the dual loop pressure
control combustion system. This system
maintains a steady output with precise
air-gas ratio. This patented combustion
control system is now used on all its
multiple burner furnaces.
QED has recently upgraded its proven
fluidbed technology with proportional,
closed-loop feedback and mass flow
controls.
The Siemens PLC-based system provides
much higher thermal efficiency and
lower fuel costs than previous systems.
Its fluidbeds operate from DV=120
to DV=240 and from 1.5t/h to 8.0t/h
production with satisfied customers on
six continents.
The latest development in galvanising
furnaces is the advanced recuperative
technology mark 4 immersion burner.
This offers dramatically higher
combustion efficiency from a double
pass pre-heat design with extended
heat-transfer area.
Constructed of stainless and high nickel
alloy steels, this modularly constructed
burner offers an extended operating
lifespan and reduced maintenance.
In addition to the fuel savings, the
new burner runs with a cooler skin
temperature providing a more pleasant
working and maintenance environment.
The company also supplies the latest
development in HighTurbulence® pickling
and galvanising technology. Its multiple
stage cleaning systems have high
turbulence acid that greatly accelerates
the pickling process. Now with computer
control, nitrogen wiping in galvanising
and Galfan offers significant savings and
accurate coating weights.
