9th ECCC European Continuous Casting Conference – ECCC 2017

For decades most radiometric sensors have been based on photomultiplier tube technology. Berthold Technologies GmbH has lately implemented the new silicon photomultiplier technology in radiometric sensors for mould level measurement. By multiple silicon based photomultiplier chips in an array, numerous benefits have be achieved. The strong temperature dependency of the silicon...

Process stability during continuous casting is an essential criterion for the production of high quality stainless steels. In particular the meniscus, which is the most sensitive zone of the whole strand, has to be in a steady shape and position. As the liquid core of the strand acts like a hydraulic hose, each radial movement of the strand shell is inducing a feedback on the mold level...

Steel meniscus fluctuations and level deformations in CC mold are one cause of the defect occurrence on slabs and later on coils. Slivers, which are one of the most costly defects observed on coils, are partly due to slag entrapment in CC mold. Actually, a strongly deformed meniscus and sudden meniscus level fluctuations favor the slag carry-away into the steel and entrapment of slag droplets...

Summary (200 to 300 words) should be concise and contain all sufficient information for a fair assessment: An essential part in the continuous casting process is the mould oscillation, crucial for flawless mould lubrication and final surface quality. Oscillation parameters, such as stroke and frequency need to be adapted to the casting speed, steel grades, casting modes etc. The first...

In order to improve operational safety and at the same time process stability and product quality, new technologies have been developed and implemented in Continuous Casting to eliminate the use of hydraulics in the casting platform area. This paper outlines the developments and technical solutions in continuous casting for hydraulic-free casting platform operation for e.g.: • Accurate...
