Lucifer Furnaces delivers custom Box Furnace for precision metal stamping operation

Lucifer Furnaces has delivered a general purpose box furnace to a manufacturer of precision metal stampings in the Midwest, USA.  Model HL7-M24 has chamber dimensions of 12”H x 18”W x 24”D and heats to 2300°F. Powered at 15 KW, heat is supplied through easy-to-replace coil wired heavy duty heating elements in V grooved radiant  panels on sides, back and door of the furnace. Insulation includes 5” of hot faced insulating firebrick with cold faced mineral wool block behind.  The roof is lined with ceramic fiberboard to eliminate cracking potential.  A 1” thick cast hearth plate protects floor insulation and provides a flat work surface.  This furnace was customized with an air operated vertical lift door activated via foot treadle enabling the door to raise to any height.  Safety features include a microswitch to auto-disengage power to heating elements when door is opened.  Temperature is controlled with a Honeywell digital time proportioning temperature controller supplemented with an overtemp controller to guard against high limit excursions.   Other special features include 3 timers -a Soak Timer for regular timing functions, an Input Timer for lower temp operation and a 7 Day Timer for auto furnace start up/shutdown.  The furnace will be used to heat treat D2 and A2 steel under air atmosphere. This furnace is part of Lucifer’s standard, general purpose, Series 7000 box furnace lines.

Lucifer Furnaces customizes box furnace for extra heavy loads for auto safety products manufacturer

Lucifer Furnaces, Warrington PA, has designed a furnace to meet the heavy loads of a supplier of automotive safety equipment. Model DL7-R24, a box furnace with a chamber size of 24”H x 24”W x 24”L was customized to support a 1000 lb. load of molds for heat treating at 750°F.  Starting with a reinforced angle iron steel frame with heavy gauge sheet steel facing welded to form a rigid unit, the furnace is lined with 6 ½” insulating firebrick and mineral wool block on side walls and below hearth.  Ceramic fiber pyroblock modules line the roof.  Coiled wire heating elements in easy-to-replace holders are located on both side walls as stacked arrays.  A special 1 ½” thick hearth plate was designed to sit atop heavy-duty piers to support the load, protect the floor insulation and provide a flat working surface. Safety features onboard include an auto-disengage feature to shut off power to heating elements when door is opened to eliminate electric shock hazard.  Controls include Honeywell DC2500 microprocessor based digital time-proportioning temperature controller programmed with a single setpoint heat ramp.  The furnace, part of Lucifer’s Series 7000 general purpose box furnaces, will be used for annealing steel and stress steel relief of die cast tool.      

Have you replaced your thermocouple lately?

Your furnace environment is wearing on your thermocouple, and a failed thermocouple can shut down production.  Don’t risk losing your product – and losing revenue.  Don’t put your production schedule on hold.  Replacing a thermocouple is easy and inexpensive.  Great idea to keep a spare in your shop!

Thermocouple failure happens – they get damaged, sheaths fail, they short out.  Contamination, corrosion, oxidation can all occur from normal heat treating.

Remember, your thermocouple tells your controller how much heat to supply to your product in the chamber.  Keep your product safe!  Keep your furnace from melting down!  Replace that old thermocouple today!  

US Auto Parts Manufacturer orders Lucifer Fiber Lined Box Furnace

Lucifer Furnaces, Inc. received an order for an electric ceramic fiber lined box furnace from a leading US stamping manufacturer of automotive products.  Model LI7-M18, with a chamber size of 12” W x 18” L x 18” H, quickly heats to a uniform 2200°F.  A hotface of 2” ceramic fiber insulation with 3” coldface mineral wool block insulation around the entire chamber maximizes heating efficiency with low power input.  Ceramic Fiber insulation, with low heat storage and low thermal conductivity combined with high thermal shock resistance, allows faster heat up/cool down cycles, reducing wait times between loads resulting in increased production.  Heavy gauge coil wound Kanthal A1 iron-chromium-aluminum wire heating elements are supported on ceramic rods effecting rapid heat up.  Elements, mounted on both side walls, can be easily replaced individually, savings costs.  A 1” thick hearth plate protects the floor insulation and supports up to 40 lbs. per square foot of hearth area.  Temperature is monitored by a rear mounted Type K thermocouple and regulated by a Honeywell DC2500 microprocessor based digital time proportioning temperature controller.  An insulated horizontal swing door with a tight seal comes standard with safety switch. Ceramic Fiber lined furnaces are general purpose box furnaces for batch heat treating in air atmosphere.
