9th ECCC European Continuous Casting Conference – ECCC 2017

With the increasing demand on casting process stability, product quality and output, there is a strong need for advanced mould monitoring techniques. Key subjects are meniscus stability, mould fluid flow and mould temperatures. This paper describes the development and application of Fiber Bragg Gratings (FBG) for mould temperature monitoring on a broad face at a slab caster of Tata Steel...

Against the background of the decisive role of heat transfer in the continuous casting mould for product quality a CFD model was developed, verified with industrial trials and applied for the adjustment of the cooling conditions in the mould. The numerical model included melt flow and solidification as well as a completely resolved cooling system, i.e. copper mould walls and cooling water...

A new advanced radiometric sensor for mould level measurement in closed stream casting has been designed by SMS Concast. The unique feature is to determine both the real position of the steel meniscus and the thickness of the lubricating powder on top. Compared to the conventional instrumentation this refined setup overcomes the limitation of measuring only a single intermediate level with no...

The key impact of mold powders on steel quality is well-recognized. However, manual feeding is still a widespread practice, leading to powder thickness variations, meniscus instability and poor process reproducibility, with negative effects on steel quality. Dedicated technologies for automated powder feeding are therefore crucial. A new mold powder diffuser with built-in optical sensor for...

The key technologies and development process for high speed casting technology were described by the study on the No.3 high-efficient slab caster of Shougang Jingtang Company. Within more than one year of technical research, some measures were applied to solve problems such as insufficient mold cooling, mold level fluctuation, and slab bulging. As a result, the casting speed successfully...
