steel wire. Its leading-edge furnaces are custom built for multi-strand annealing, stress relieving, patenting and tempering processes. With patented ow technology, its uid systems integrate cleaning e ciency with high wire speeds. QED’s rugged liquid metal furnaces apply heavy and commercial coatings of zinc, aluminium and Galfan®. With a bed of ne aluminium oxide particles and precise air and gas control, QED’s uid bed furnaces o er an environment-friendly heat-treating solution in an energy-e cient package. The uid bed’s rapid heat transfer results in a shorter furnace length, providing more compact and easier-to-operate process lines. The addition of pulse- ring technology to QED’s mu e tube austinitising furnace improves the thermal e ciency and increases temperature uniformity, due to the higher average ame velocity and superior convective heat-transfer. Pulse ring also o ers a higher turn-down ratio, lower NOx emissions, and more exibility in burner and zone control. An S7 Siemens PLC is at the heart of its furnace control systems. Programmed

The latest development in ceramic-lined furnaces is the Mark 4 advanced recupe- rative technology immersion burner. This burner o ers higher combustion e ciency from an extended double pass pre-heat design. Constructed of stainless and high nickel alloy steels, the burner has an extended operating lifespan and a cooler skin temperature. QED’s latest wire cleaning equipment is a dual-stage pre-cleaner with ultrasonic transducers. The laser-cut stainless steel tank incorporates new temperature and level control features. The wires exit the cleaning section into a triple water rinse with four-stage suction wiping. The HighTurbulence™ pickling system optimises uid ow to breakdown the static boundary layer surrounding the wires and to rapidly remove scale. With multiple cascading stages, this e cient system lowers acid consump- tion and minimises waste treatment requirements.

with user-friendly software and advanced combustion algorithms, the furnace control delivers precision gas ow and accurate temperature control. Among other developments is a web-enabled system for smartphone monitoring and remote troubleshooting of control panels. With a view to improving e ciency and minimising environmental impact, QED developed the dual loop pressure/ temperature combustion control system. This patented system maintains a steady output with precise air-gas ratio on all of the company’s multiple burner furnaces.
