equipment for wire treatment

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. Heat treating, cleaning and coating

QEDWire’s 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.
