Crucible Furnace
Model 1700°C, Top or Bottom Loading
The
Model CF56724C Crucible Furnace is used for high temperature research under
three methods of processing: air, controlled atmosphere, or vertical tube
orientation using an interchangeable vestibule as an insulating sleeve (which
requires a vertical tube adaptation kit).
Graduated density Moldatherm® insulation combined with
a unique right-angle bend heating element, sidewall mounted, delivers excellent
chamber uniformity, fast heat-up and recovery, and energy conserving performance.

| PROCESSING OPTIONS | |
| In addition to air processing, the 1700°C
crucible furnace can be used for atmosphere processing using an inverted
ceramic crucible over the load forming a muffle. Inert gas is supplied
through inlet and outlet tubes (customer supplied). Gas flow is controlled
via an adjustable N2 flowmeter, included. For use in a vertical tube configuration, either air or controlled atmosphere processing, the furnace requires an optional Adaptation Kit ordered to match the size of the desired process tube (customer supplied). |

| VERTICAL TUBE ADAPTATION KIT | ||||||||
| The Vertical Tube Adaption Kit creates a 1700°C tube furnace with air or inert atmosphere control using the Model CF56724C crucible furnace as the heating source. Each field installed kit (see ordering chart) is selected based on intended process tube size, and includes two tube vestibules (D), two tube insulating sleeves (B) with cover plate (C) and outlet plugs (A). Process tube and atmosphere piping are not included. Contact us for more information. | ||||||||

| CONTROLLERS | |||||||||||||||||||||
| 1700°C Controller, Programmable, With Communications | |||||||||||||||||||||
|
Lindberg/Blue M 1700°C Programmable Controller provides 300 programmable segments for a variety of ramp (up and down) and dwell (timed holds) settings. Controller will accept up to 30 individual programs with up to 99 segments per program. The controller visually displays ramp rate, dwell time, program segment and percent power output. A holdback feature allows the operator to set a -process vs. setpoint" temperature value which, when exceeded, holds the program to allow the process to catch up. The controller includes an advanced self-tuning feature which automatically sets the best PID settings for the thermal process. Two digital displays simultaneously indicate actual temperature and setpoint temperature. High limit overtemperature protection is standard. The control console includes a circuit breaker, power module, transformer and cooling fans. Controller includes RS485 data port (communications card and port) for connection to remote computer, allowing modification, interrogation and data transfer of all instrument control and configuration parameters. Software not included, but is available as an accessory. |

| Option B Overtemperature Control (OTC) | |||||||||||||||||||||
| Adjustable digital overtemperature control, factory installed on selected control consoles with "B" designation; see chart. Protects furnace and load in the event of primary control circuit failure. Overrides main controller, assumes temperature control and shuts off power to furnace if high limit is reached. Manual re-set required for safety. Operates via signal from independent thermocouple. | |||||||||||||||||||||
