Series 5000 EQ - Heavy Duty Elevator Quench Controlled Atmosphere Furnaces
Elevator Quench Furnaces designed for 1900°F operation combine a hardening chamber, elevator vestibule and quench tank in one complete assembly. The workload is processed in the furnace chamber, transferred into the holding vestibule and lowered by an air-operated elevator into a quench tank while the parts are protected by atmosphere during the entire cycle. The furnaces are complete with an alloy muffle which separates the atmosphere and workload from refractory and elements, and an inner door which separates the furnace chamber from the vestibule section. An outer door provides a positive seal against the vestibule. The EQ Models operate under a positive flow of protective atmosphere to minimize scale and oxidation on most tool steels. This design achieves lower dew points, reduces atmosphere consumption and shortens purge time.
Ruggedly constructed and rated for work loads up to 40 lbs. per square foot of hearth area. All models are completely wired, test fired and shipped ready for connection to main power and regulated atmosphere pressure of 5 PSI. Simple, safe, dependable operation. Available in 18 standard sizes. All models will operate with inert atmosphere. Flammable atmosphere may be used with the addition of Atmosphere Safety System per NFPA Code 86 C.
