QPT series is a new type of annealing (normalizing) furnace derived from QT and QZT types. lts proprietary energy-saving technology and faster annealing process can save approx 1/3 of the energy as compared with QT or QZT types, and save approx 1/2 of the energy as compared with bell furnaces or pusher furnaces. It can be heated by natural gas or coal gas etc. This type of furnaces are applied for continuous annealing (normalizing) treatment on alloys of bearing rings, hardware tools, tubes, rods, coils, strips, balls and toolings , as well for pre-heat treatment on precisely forged, cold-formed and cold rolled parts.
