Lucifer Offers Line of Protective Atmosphere Elevator Quench Furnaces for Heat Treating Applications



May 16, 2005 -- A comprehensive line of protective atmosphere elevator quench furnaces, combining pre- heat section, hardening chamber, cooling vestibule and quench tank in one integrated unit, is available from Lucifer Furnaces, Inc., Warrington, PA.
   
The furnaces, which are designed for 2100 degrees F operation, are available in eight standard sizes, ranging in workload capacity from 15 to 55 pounds. Furnaces in the series (#7022 EQ) are ideal for low production, scale-free applications.
   
To guard against exposure of the workload to the oxidizing effects of air, the system features:
   
- A continuously controlled atmosphere -- from hardening chamber through vestibule to quench tank -- to maintain workload protection throughout the heat-treating operation.
- An inner, vertical lift door separating the work chamber form the vestibule.
- An alloy retort, gasketed to the inner door assembly, to segregate atmosphere and workload from the refractory and heating elements.
   
The series is available with a number of options, including pusher rod assembly, air- operated doors, fan-or-water-cooled vestibule, quench tank agitation and heating, sight ports, flowmeter and regulator.
   
Other options include:
- Flammable/combustible atmosphere operation -- with the addition of required safety equipment.
- Fully automated operation -- with the addition of sequencing timer, push rod assembly, and automatic door and elevator operations.
- Continuous feed operation with pre-heat section, hardening chamber, and vestibule in a straight through configuration.
   
All furnaces are standard with digital temperature controls and are completely pre-wired, tested and shipped ready for connection to user's power and atmosphere supply. Furnaces operate on 230 or 460 supply voltage; control system on 115 volts.
