QED Wire Lines Inc, Canada, specialises in
the treatment of steel wires. After being
drawn to the required size, wire will
usually need some type of heat treating,
a cleaning process and the application of
a coating.
Heat treatment can take the form of
annealing, stress relieving, patenting or
oil tempering, depending on the carbon
content and the required tensile. QED
Wire’s FastHeatTM Fluidbed furnace is
used to heat treat multiple strands of
drawn wire, and offers increased furnace
efficiency due to the newly developed
‘Production Proportional Algorithm’
used on the company’s PLC-controlled
furnaces. The algorithm provides tighter
control of fluidisation rates in proportion
to changing production loads.
Advantages of QED’s fluidbeds include
rapid heat-transfer to the wires, reliable
performance, high thermal efficiency at
full production, quick start-up and shut-
down, multiple zone control and flow rate
control, and a double sand return system.
For surface treatment, QED provides high
speed cleaning and descaling solutions
with its HighTurbulence® Pickling System.
This fumeless system provides an
environmentally friendly replacement for
older cleaning baths.
The patented special nozzle configuration
produces highly turbulent acid throughout
the processing tray that accelerates the
pickling process and shortens immersion
lengths, and the multiple stage design
uses the acid more efficiently, resulting in
lower acid and waste treatment costs.
Wire coating can take the form of
phosphate, borax, aluminium, zinc or
Galfan®. QED’s ceramic lined Galvanizing
and Galfan® furnaces are supplied with
fuel efficient patented burner pressure
control systems. The company also offers
advanced wiping systems: both vertical
pad wiping and the latest generation
nitrogen wiping systems are available in
modular units, ensuring high wire speeds
and production flexibility.
