High temperature recirculating ovens
A new line of high temperature recirculating ovens (4099 V Series), engineered for the heat treatment of large workloads, is offered by Lucifer Furnaces
Furnaces in the series (#7022 EQ) are ideal for low production, scale-free applications.
To guard against exposure of the workload to the oxidising 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 460V supply voltage; the control system is on 115 volts.
