QED presenting pulse-firing muffle tube furnaces at Interwire

As a muffle furnace manufacturer QED austenitizes or anneals multiple wire strands in a protective environment thereby eliminating most scale formation on the wire. The QED Muffle Furnaces are heated by high velocity burners mounted along both sides in a staggered pattern, and firing both above and below the muffle or tube field.

The addition of pulse-firing technology to QED’s muffle tube austinitizing furnace improves the thermal efficiency and increases temperature uniformity. This is owing to the higher average flame velocity and superior convective heat-transfer. Pulse firing also offers: a higher turn-down ratio, lower NOx emissions and more flexibility in burner and zone control.

QED specializes in equipment for in-line heat-treating, cleaning and coating of steel wire. The leading edge furnaces are custom built for multi-strand annealing, stress relieving, patenting and tempering processes. With patented flow technology, the fluid systems integrate cleaning efficiency with high wire speeds. QED’s rugged liquid metal furnaces have proven the test of time applying heavy and commercial coating of zinc, aluminum and Galfan®.
