"rave-minerals" Process Temperature Control Rings
(PTCR) from 850°C up to 1750°C |
특징 및 용도 (Features & Applications)
■ PTCR: What it is
The PTCR ring is a highly accurate ceramic temperature
indicator which records the true heat treatment received by the fired product.
PTCR rings take account of both radiated and transferred heat, as well as the
effects of temperature over time. lt conveniently allows this recorded heat
exposure to be expressed as a single number - ring temperature (RT) - which is
practical and easy to work with.
PTCR rings can be used in both batch and continuous kilns & furnaces; they
are used in a range of atmospheres including oxygen, nitrogen, air and vacuum.
Five different PTCR types are available - standard height is 7.0 mm (3,5 mm also
available) - covering a range from 850 to 1,750°C. Ring types are identified by
color coding and batch and type numbers pressed into the ring.
■ PTCR: How it works
When exposed to heat in the kiln &
furnace, the PTCR ring contracts - and continues contracting as the top
temperature is maintained over the time. The degree of contraction is almost
linear over the complete operating range of the PTCR, providing a practical
measure of the accumulated heat to which the ring - and the fired products -
have been subjected. The amount of contraction - the amount by which the ring
diameter has shrunk - is measured with a numerical or digital micrometer. This
measurement can be converted to 'ring temperature' for ease of comparison and
correlation to the firing process (temperature tables are supplied with the
rings).
