The LB 352 Mold Level gauge has
become the standard for measuring mold level in the steel
industry.
Continuous Casting Level Measurements
The measuring system detects the actual level
within a measuring range of approx. 100 to 300 mm. In connection
with downstream control, automatic
casting and fully automated cast-on becomes possible in many
continuous casting facilities.
When designing the level
gauging system, the special features of the production process
and possible contingent conditions should be taken into account,
in addition to the actual measuring task. Therefore, full information and
dimensional drawings should be provided.
The Mold Level Gauge LB 352 operates according
to the radiometric principle, utilizing the physical law that
Gamma radiation is attenuated as it passes through matter. Since
source type, wall thicknesses and radiation path are constant,
the measurement can only be affected by the mold level. All
other physical properties, such as temperature, dirt and vapor
have no influence. Since the absorption law follows an
exponential curve, the measuring effect with typical mold
dimensions becomes practically independent of the interference
factors mentioned
above.
As a consequence, the radiometric measuring
method features a high level of operational safety and requires
practically no maintenance, even under difficult operating and
ambient conditions. The use of scintillation counters as
radiation detectors and careful project engineering ensure that
the lowest possible source activities and the best shielding
will be used. The radiation exposure of the operating staff will
clearly stay below the extremely low values permitted by law,
which are about as high as natural environmental radiation.
Adaptation to Mold Construction
Careful adaptation to the mold construction
allows you to keep the source-detector distance at a minimum and
reduce the wall thickness to be irradiated. Consequently, a
lower source activity will be required and the measurement
geometry is optimized.

The LB 352 contains a variety of highly
sophisticated scintillation detectors. Depending upon the
particular mold level application, Berthold Technologies will
specify the correct detector and crystal size for your
individual application.
