Series 653 High-Temperature Furnace Operation 31
Operation
Prior to performing a materials test at high temperatures, familiarize yourself
with the operation of the other components that make up the complete testing
system.
Adapting furnace
insulation
Before using the 653.01 or 653.02 furnace, you must file holes in the upper and
lower layers of insulation to accommodate the ends of the specimen. These ends
extend outward from the furnace toward the grips. Filing the insulation produces
dust. Be sure to use proper filing methods when working with or handling
furnace insulation.
Proper furnace use
• To reduce the possibility of damage to or destruction of the furnace, make
sure that the hydraulic control electronics are set for appropriate
displacement limits.
• When maximum operating temperatures are to be used, note the maximum
recommended heating ramp is 100°C (212°F) per minute.
• The heater elements are designed to operate at temperatures between 100°C
(212°F) and 1400°C (2552°F). Using the furnace above 1400°C can
significantly shorten the life of the heating elements and insulation.
Improper use can shorten the life of heater elements and insulation
components.
Do not open the high-temperature furnace while it is hot or operating. Allow
sufficient time for the furnace to cool before opening the furnace. Rapid
cooling reduces heating element life.
Avoid contacting the heating elements when installing a test specimen or test
fixtures. The heating elements are easily broken.
Avoid contaminating the heating elements with foreign substances which can
reduce service life. Wear gloves if it is necessary to handle heating elements.
Explosions in the furnace can cause death or serious injury.
Do not use this furnace to heat materials that pose hazards of explosion,
implosion, or the release of toxic or flammable gases
