Lucifer Furnaces, Warrington, Pa., announces that it has delivered an air recirculating oven, a salt bath pot furnace, and a quench tank to Vermont Custom Gage LLC, a subsidiary of Vermont Precision Tools Inc., Swanton Vt. The new equipment will be used in the production of small steel component parts of its measuring (gage) equipment.
The oven, a 4000 series model 48-R36 with working dimensions of 24x24x36 inches, heats to 800°F and will be used for tempering. It is insulated with 6.5-in. multi-layered lightweight firebrick and block insulation, and a roof lined with ceramic fiber modules. The oven features a stainless steel liner that isolates the workload from the heating elements and directs airflow in a horizontal pattern.
A high CFM fan assembly mounted through the oven rear wall circulates air over heating elements and back through the work chamber. The horizontal swing door is mounted with heavy duty hinges, 6 inches of insulation, and two cam latches for a secure seal. After pre-heating, parts will be loaded into the salt pot furnace, model 2055-1624, and then oil quenched in a Lucifer Quench Tank, QT-2020, complete with air mixer, heater and soak timer.
Next, the tools will be loaded into the 4000 series, model 48-R36 oven to be held at a constant temperature over a period of time to stabilize the structure of the steel.
