“测温环FERRO 美国测温环总代理 北京宏富信”详细介绍
Method of use
PTCR rings can be placed at almost any location in the kiln, on kiln furniture, trolleys or transports. The use of both multi-location and
multi-level positioning is recommended, as this provides the most insight into the heat treatment distribution within the kiln.
The contraction of the PTCR diameter reflects the actual heat treatment at the point where the ring was located in the kiln. The diameter
is easily measured using a PTCR micrometer - only a single measurement is required (as shown).
PTCR micrometers Numerical (N) and Digital(D) have an integral, ergonomically designed solid base with a ring positioning chuck, which ensures the ring is always correctly positioned in the micrometer. This design not only simplifies the measuring process, but also
improves the repeatability and reproducibility of ring temperature measurement.
Converting to ring temperature
The measured ring diameter is converted to ring temperature using the conversion table enclosed in each packing unit. Each table is
specific to the particular batch of rings, for accuracy and convenience.The ring temperature is a practical single number which is useful for comparison purposes - for instance to relate the recorded heat treatment to the firing process and defined standards - so that any required adjustments can be made. It does not necessarily reflect the actual kiln temperature; the PTCR acts as an accumulator, measuring the total heat treatment over time, rather than the maximum temperature attained.
Establishing a standard ring temperature
In order to make ring temperature comparisons between different firings, a standard ring temperature must be defined. This is done by
including PTCR rings in a series of firings, and relating their ring temperatures to the quality of the products produced.
The ring temperature which corresponds to products fired to the correct specifications can be used as the standard.
