The quickest mould level sytem
of measuring steel meniscus
Precise and quick measurement of mould level lays the foundation for the production of high quality steel and the reliable prevention of the overflow and breakout of steel. The castXpert LB 452 has been setting industry benchmarks for years, delivering highly accurate and stable mould level control.
- The world’s fastest response – with the extremely short cycle time of 5 ms
- Fully compatible with electromagnetic stirrers and brakes
- Reliable and extremely robust mould level measurement
- Highest safety, designed according to IEC 61508 (SIL Standard))
- Highest accuracy

Measuring the true steel level in closed casting
Determining the powder thickness
Our advanced detector delivers real-time, highly accurate measurement of both molten steel level and powder height in one compact unit. Using ten scintillation crystals combined with advanced algorithms, it uniquely separates molten steel from the casting powder layer with unmatched accuracy.
- Prevent overflows, minimizing strand breakouts and costly downtime
- Exceptional mould level stability, ensuring consistently superior steel quality
- Process automation by integration of automated powder feeder
Mould powder measurement cycle of 250 ms

State of the art steel level control technology

Full steel level control of the production process
Our mould level measurement solutions are designed to run at an exceptionally short cycle time of 5 ms, allowing for perfect control of the casting process – both at automatic start-up and in normal operation. Extensive self-diagnostics as well as plausibility checks of calibration and measurement ensure the highest process precision and product quality. Each steel control system measures up to four strands simultaneously. Also each measurements channel is equipped with its own dedicated processor and power supply. Thus, all four channels work independent of each other and high process reliability is guaranteed.

CONTROL UNIT WITH TOUCHSCREEN
castXpert LB 452

Extremely fast
The unique short cycle time of 5 ms provides the ideal basis for reliable control.
Detector status
Detector temperature and status are continuously monitored and displayed.
Safety
Comprehensive self-diagnostics and plausibility checks of measurement and calibration ensure the highest process reliability.
Highest accuracy
By using several calibration points, non-linearities of the calibration curve are eliminated completely, and high accuracy can be achieved over the entire measuring range.
Designed according to IEC 61508 (SIL Standard)
Easy to use
The large colour touchscreen makes operation and calibration particularly easy. The ability to select from different operating languages facilitates ease of operation. Regardless of where the system is installed.
Automatic start-up
Benefit from faster response times during start-up of casting, by the ability to set a smaller time constant in the low measuring range.
4 measuring channels
Up to four strands can be measured simultaneously. Each measurement channel is equipped with its own power supply and CPU. Therefore, the channels are independent of each other and high process reliability is guaranteed.
Monitored current output
Continuous monitoring of the current output ensures highest reliability and signal stability. This plausibility test is patented.

Whitepaper
Measuring the steel level in continuous casting
Radiometric based mould level measurement is the dominating technology for measuring the steel level in continuous casting. Herein we discuss performance, statistical variation, influencing factors, source selection, and a recent development that enables the simultaneous measurement of casting powder layer thickness.
