Designed for all casting applications

GAMMAcast detectors are characterized by their excellent sensitivity, leading to a significant reduction of source size. The robust detector design and the PlugProtect cable connection ensure highest mechanical stability and longest lifetime.
As a direct request from several key-customers in the steel industry, we have also offer a shorter version of the LB 6760 GAMMAcast detector.


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.
