State of the art steel level control technology

Full steel level control of the production process

Our mold 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.

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.


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.


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 that recent development has brought the ability to also simultaneously measure the thickness of the casting powder layer. Continuous casting improves quality and reduces the production costs considerably. These advantages, as well as the improvement of the process in general, have led to the fact that today almost all steel production is done through continuous casting.
