SUMMARY:Review of powder thickness control approach for submerged casting stream
DESCRIPTION:During the last years, the importance of powder feeding has become more and more central for the optimization of the continuous casting process with submerged stream. A first technological step ahead has been the introduction of the powder feeder enabling to keep constant the addition of lubricating powder and keep homogenous its distribution.
A huge added value is given by the powder thickness control in close loop. This is possible thanks to the integration in the system of a dedicated sensor which operates by comparison with the main sensor for steel level control. The advantages of this solution are several, as keeping constant the thickness of lubricating powder, reducing the steel level fluctuation, reducing break-outs risks, reducing powder entrapments into liquid steel.
The solutions for the powder thickness control here reported are classifiable in two families: sensors to be installed on the casting floor (as for example laser triangulation) and sensors installed in the mould assembly (as UT-POWDER installed in the water jacket/backplate).
The sensor for powder thickness control installed on the casting floor presents the advantage that one sensor is common for more casting sizes, but there are limitations due to geometrical dimensions, to steel level sensor characteristics, and also to the operativity, being installed on the casting floor.
The UT-POWDER, ergolines solution installed in the mould assembly, presents several advantages such as non-interference on the operativity of personnel on the casting floor, a wider application range, and the possibility to gather some additional information as thermal profile in the meniscus area.
