Furnace specialist, QED QED Wire Lines Inc is a long-standing specialist in furnaces for heat-treating and coating steel wire, where multiple strands travel through the equipment at relatively high speeds.

To improve efficiency, and minimise environmental concerns, QED has developed the dual loop pressure control system – a new system of burner control that maintains a close air to gas ratio while allowing for stopping and starting burners without changing ratios. This system has proved so successful that the company has received a US patent for the technology. QED Wire Lines now uses this combustion control system on all multiple burner furnaces such as oil temper lines, patenting and autenitising furnaces as well as galvanising and Galfan coating furnaces. Another specialism is the Fluidbed heat-treating furnace, a technology well

proven for in-line annealing, stress relieving, tempering and quenching. For increasing numbers of users who run their lines twenty-four hours a day, seven days a week, even small maintenance items can be a problem. With QED design these maintenance areas are all but eliminated. New QED furnaces have a fuel injection system that avoids the need for distribution plenums, porous bases and a new proportional control system to improve efficiency. The previous heat loss problems, due to poor sealing of the threading openings, have been eliminated with a new labyrinth seal system. The improved design minimises sand drag out and greatly improves the sand handling technology. In a niche market, all furnaces are custom designed to suit the individual user and application.
