An electric box furnace, currently headed to a Midwest equipment provider, will ultimately be installed at a Snap-on production facility that services tool and die support within the company’s production line.
The model QDD29 economical dual-chamber heat treating and tempering oven from L&L Special Furnace has a compact over/under design that saves floor space and provides reliable heat treating in-house.
The top chamber is primarily deployed for heat treating tool steels at temperatures up to 2200°F; the tempering chamber is suited to temperatures up to 1250°F and has a recirculation baffle that makes it suitable for small aluminum work as well. The hardening and tempering chambers have interior dimensions of 12” wide by 8” high by 24” deep, with total external dimensions of 55” wide by 70” tall by 56” deep.
The QDD29 is controlled with digital single setpoint controls along with overtemperature protection. Solid-state relays drive the heating elements in a control circuit.
