Industrial Furnaces Terms
–
The processes of heating, holding temperature and cooling in order to
accomplish a specific objective with the material being heated.
– A structure
that can be developed from the hot rolling of steel, resulting in a layering
effect.
– Annealing
done in an extremely hot atmosphere that prevents the occurrence of discoloration
and may reduce oxides.
– Heating the surface
of steel in contact with carbon-rich solids, liquids or gases in order
to add carbon to the material.
– Making the
surface layer of a steel material substantially harder through heat treating.
– The separate
sensor or instrument of a piece of thermal processing equipment which
controls its own temperature individually.
– A process
that is used to deter cracking or hardening or to achieve a desired microstructural
result. The controlled cooling process involves cooling the material from
an elevated temperature in a selected method.
– Stresses
resulting from irregular temperature distribution during cooling.

– Enclosures that are used for a wide variety of process heating
applications.
– Heating material
or products prior to a subsequent thermal or mechanical treatment.
– Quickly cooling
from a high temperature.
– Placing parts on a
rack or tray prior to heat treatment in order to prevent heat-related
distortions and to keep the parts separated.
– A term describing
materials that have a very high melting point, making them ideal for linings
of furnaces and kilns.
– Surface flaking or
chipping resulting from improper heat treatment or material dissociation.
– A quick cooling
process in which spray nozzles are used to spray water or other liquids
on a part.
– The
process of heating a part to slightly above its normal operating temperature
and then cooling it to room temperature. Stabilizing treatments are done
prior to finishing the part to final dimensions and for the purpose of
ensuring dimensional stability.
– A heat treatment
done at low temperatures in order to balance stresses in a cold-worked
part without decreasing the mechanical strength imparted to the product
through the cold-working process.
– Heating and
holding the desired temperature long enough to reduce residual stresses,
then slowly cooling.
– Heating at a
temperature above the point where equilibrium phase transformation should
occur but without actually making a transformation.
– A device that
measures temperature through thermal electromotive force.
–
The temperature equilibrium at which a change in the phase occurs.
– A quick cooling
process using water as the quenching medium. Water quenching is inefficient
at the beginning, or hot, stage of the quenching process.
