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.
