PROCESSING FURNACE SYSTEMS
Automatic Processing
Furnace Systems (APF) and Ceramic Processing Furnace Systems (CPF) are from the Astro
Division of Thermal Technology. They provide fully automatic, unattended operation at
temperatures to 2000° C. Parts processing may be cycled in under two hours with rapid
temperature ramp up (>100° C/min) and ramp down (>300° C/min).
These systems may be configured as a hydrogen furnace, a vacuum furnace,
or both.
Hot zones are designed to operate
in wet or dry hydrogen, fully dissociated dry ammonia, inert gases, nitrogen, or vacuum.
The large surface area heating elements provide excellent temperature uniformity within
the working volume. Molybdenum sheet, molybdenum wire mesh, or tungsten wire mesh heating
elements are used, depending on the operating temperature. A variety of work volumes,
temperatures, and processing capabilities are offered to match the system to the
customer’s requirements.
The APF/CPF systems are cold
wall, radiation shielded, bell-style batch furnaces. The double-wall, all stainless steel
furnace chamber hydraulically lifts off the base plate and hearth, providing full work
area access for loading parts and instrumentation. The furnace system uses a
microprocessor for digital temperature control and processing sequences. More than 25
separate, complete processing programs may be held in memory at one time. Programs are
easily entered and may be modified during operation on a temporary or permanent basis.
After loading and starting, operation is fully automatic. An audio/visual alarm signals
the end of a cycle.
