MEASUREMENT TECHNOLOGY

Mold level measuring principle by Berthold!

Gamma radiation is attenuated as it passes through the mold. This attenuation is measured by a detector. The extent to which the radiation is attenuated depends on the mold level. The higher the level of molten metal in the mold, the less radiation will reach the detector. In this manner, the mold level can be reliably monitored – irrespective of dust, temperature and vibrations. The radiometric measurement is maintenance-free and applicable for all mold types and sizes. Beside the typical installation on slab and billet casters it is also successfully applied on beam-blank and round casters.

AOS - Activity Optimized Source

In this particular type of rod source the accu­racy in the upper part of the measuring range can be increased significantly by optimizing the distribution of activity. Especially for small for­mats the statistical noise is minimized, without increasing the overall activity of the source.
Or if you are content with the accuracy? In this case AOS can be used to reduce the source activity while maintaining the same accuracy. Depending on the application, the use of smaller shields is possible. In many cases the more cost-efficient lead may be used instead of tungsten.
