Unpredictable slag carry-over from ladle to tundish represents a serious problem, which can lead to either steel impurity or poor ladle yield. Ergolines VSD gives the right balance.
VSD, vibrational slag carry-over detection sensor. The system early detects slag carry-over from ladle to tundish, thus allowing the operator, or an automatic control system, to shut-off the ladle, preserving steel purity in the tundish.
The threshold of intervention is user-programmable so as to allow a choice between steel purity and yield of the ladle.
VSD is based on vibration measurement techniques by means of tri-axial high-precision accelerometers and sophisticated digital signal processing.
