Lucifer Furnaces Pot Furnaces for Aerospace Applications

 

Lucifer Furnaces, Warrington PA, has designed a multi-unit modular Pot Furnace system for a major Aerospace Manufacture in the US.  The end user is adding these furnaces to existing Lucifer Pot Furnaces in order to increase heat treat capacity.  Each of the 4 Model 2057 Pot Furnaces is connected to a single freestanding NEMA 1 control panel.  Each furnace is heated electrically with 18 KW of power to heavy duty coiled elements in removable holders on all 4 side walls.  Roof and side covers bolted to the frame of each furnace can be removed for easy service access.  The units are insulated with 5” of multi-layer insulation consisting of dry-fit hot face lightweight firebrick backed by cold face mineral wool.  A vestibule at the top of each furnace reduces heat loss between the pot wall and firing chamber.   The 10” ID x 10” Deep pots are constructed of RA300 alloy with 3/8” thick walls designed with a flange for sealing against the roof plate to minimize heat loss.  Controls onboard include Honeywell DC3500 digital multiprogrammable cascade controllers which automatically interpret multiple thermocouple readings and adjust the inside/outside pot temperature to achieve the desired set point.  Additional energy efficiency and power uniformity is maintained with SCR power units.   Temperature is monitored with control thermocouples in the firing chamber between the heating elements and pot wall as well as separate sheathed thermocouples located in the pot.    An overtemp system adds a safety feature by allowing for unattended operation and automatic shutdown in the event of an overtemp excursion.

Lucifer Furnaces ships 7th Large Dual Chamber Furnace to OEM in USA

 Lucifer Furnaces has shipped a 7^th large Dual Chamber 8000 Series Furnace to a US auto manufacturer.  Each chamber is 24” H x 24” W x 36” L.  This heavy duty Furnace-over-Oven features 12-gauge sheet steel construction with reinforced members for a solid framework.  The upper hardening chamber heats with 45 KW power to banks of elements on sides, door and back.  The heating elements are designed with heavy gauge wire mounted in removable holders.  The upper chamber cast hearth plates support the workload and can be easily replaced without disturbing the heating elements.  The lower tempering oven with 20 KW power features a stainless-steel liner shielding heating elements from the workload.  This liner was designed as a 3-sided liner with a cast hearth plate for durability.  A high cfm, ½ hp fan recirculates air past the elements and back through the chamber in a uniform pattern.  This unit was customized with a free-standing control panel providing the ability to separate control operation from the furnace environment.   Each chamber has been outfitted with Honeywell Multi Program Controllers with a High Limit Backup Controller to prevent temperature excursion events

Lucifer Furnaces delivers customized Recirculating Oven to Auto Supplier

 Lucifer Furnaces recently delivered a large 4000 Series Oven to a leading Automotive Supplier in the U.S.  Model 42-T36 has a chamber size of 30”H x 30”W x 36”L, heating to 1200°F with 35 KW of power.  This model is complete with a high CFM rear mounted fan assembly to recirculate the heated air uniformly throughout the chamber.  A stainless-steel liner isolates the heating elements from the work area and directs air forward over the heating elements and back through the chamber in a horizontal pattern for uniform heating.  This furnace was customized with a heavy duty cast work tray which sits on the floor of the chamber inside the liner area to support the workload and protect the floor brick.
