Paragon HT Series Heat Treating FurnaceThe Paragon HT Series will save machine shops valuable time with a furnace at their disposal in their own shop. You will no longer need to send a die out for heat treating, wait for its return, and then send it out again for additional heat treating.
Solid constructionThe door swings open with a one-handed operation. A counter-weight handle holds the door securely closed. The door has a vent hole, so you can see inside the furnace during firing. Metal covers close the vent holes when not in use. (Always wear Paragon firing safety glasses when looking into a hot furnace.) The furnace is insulated with refractory firebrick. The elements are mounted in dropped, recessed grooves machined into the firebrick. This groove protects the element for long life and low maintenance. Elements are simple to replace. You can thread new elements into place following clear instructions in the manual. The door is mounted with a heavy-duty hinge for a smooth opening. A micro-switch shuts off the power to the elements when the door is opened. We use high-temperature wire in the switch box for long life. A heat shield, mounted between the switch box and furnace, helps keep the switch box components cool even during extended operation. To further dissipate heat, the switch box is extra large and generously ventilated.
Printed instructionsYour furnace includes a wiring diagram, programming instructions, and basic heat treating manual. The manual is written in plain English for the beginner.
Optional gas injection flow meterDuring heat treating, scale forms on the surface of the steel. One way to eliminate most scaling is to wrap the steel in stainless steel foil. Or you could install the gas injection flow meter on your furnace. The meter regulates the flow of inert gas, such as argon, inside the furnace. The gas displaces the oxygen to prevent most scaling.
